Hi everyone,

For all of you who have been patiently awaiting some sort of news about the CBG's future, this will be a long-overdue announcement. After a long period of discussing and trying out a few things (interlaced with banter and truly epic discussions on the Discord server), we've decided that we are in fact going to build a new forum to let us continue to operate with more-or-less the same format, rather than try and transition to something such as a sub-Reddit. Here's what this means:

  • We'll be locking down the current forums shortly into read-only mode, to avoid missing new work that might get posted, and to avoid accidentally destroying the data.
  • The plan is to transfer as much of the existing content as possible. In a best-case scenario this means that we'll get a mostly-seamless transfer of the content to an updated forum that you'll be able to log into like normal and continue posting. Worst-case scenario, we end up having to lock down the old forum as an archive for reference, but you'll have to restart/rebuild any threads for settings etc.
  • Nomadic and I are going to generate some backups and see what things look like after working through the data. Once we've determined which of the above scenarios has come to pass, I'll open up the new site and help people start signing up/logging in (I'll make sure anyone who requests it has their account reserved, too).

In the meantime, you can find us on Discord (use that link to be invited; you'll need sparkletwist or I to add you to the Members group there to see channels other than #general-chat). If you have any questions, ping us there or email me at tvgamblin @ gmail . com.


Homebrews (Archived) / Re: the decaying world of Elyden
« Last post by vorropohaiah on March 25, 2019, 11:33:53 AM »
How's this for thread necromancy?

I've been beavering away at the world for some years now, creating a LOT of maps, history and lore, with an eye towards printing two books (mostly for my own amusement, though some internet-dwelling people have shown an interest in them): an Encyclopaedia and an Atlas.  

Some things to know about Elyden
  • 1) Decay: Elyden is a dying world. The seas are slowly retreating, Ice in the north and south poles Is growing every year and the sun is slowly goring weaker. Empires built atop the ruin of older empires are crumbling to decadence and greed. Resources are waning. Life is cheap (to the common folk, at least).
  • 2) Ancient: We are now in the Fifth Age, which is around 5,000 years old. Most Fourth Age and early fifth Age nations are ruined and unknown to unlearned people, their ruins either forgotten and consumed by the elements or serving as the foundations for today’s cities. The Third Age is considered near-mythical and is the basis for many folk tales and legends, with fantastical races and beasts that are now extinct.
  • 3) Demiurges: Elyden (and the universe that supports it) was created by 22 Demiurges (gods) whose hubris led to their fall and banishment to the mortal realm, where they each became leader (some willing, others unwilling) to a mortal tribe (of which humans are one). Most demiurges are now ‘dead’ (death to a demiurge is similar to a coma, their dreams and nightmares manifesting in the land surrounding them). The Demiurges sired scions, the descendants of which still possess traits and powers from their demiurge sire. Few scion-born know of their divine heritage and what powers or traits they have are so diluted as to not be of import.
        The Demiurges are largely forgotten, remembered or worshipped as corrupted versions without most known the truth (save one, who has cunningly adopted the human race as his own and become the Undying Machine – god of the nation of Korachan, interred in a life-support machine deep in the Karkharadontid desert – a site of pilgrimage to his faithful). More on the Demiurges can be found here.
  • 4) the Materia Omna: the chaotic matter from which the Demiurges shaped the universe. Their stirring caused this chaotic sea to divide into two – the Firmament above and the Atramenta below. These are collectively known as the Materia Omna and are the fuel that power acts of shaping (magic). The two opposing energies manifest on Elyden through two antipodeal fonts – the Black Fountain and the Meniscus, for the Atramenta and the Firmament, respectively. More on this here.
        The Firmament and Atramenta also leak into the material realm, resulting in tainted regions that are quantified in varying degrees, from mild to those that are so inimical to life, warping the natural laws of the world in strange ways, as to be shunned by mortals.
  • 5) Dreams: dreams are tangible forces thanks to the actions of the Demiurges. They can be planted, read, examined and altered by Oneiromancers. They can also be travelled to and explored, though dreamrealms are dangerous and mutable, subject to the dreams and nightmares of the Demiurges. They can exist in one of two forms – either as physical tangible places that can be mapped and explored (insofar as a mutable dreamland can) through mundane means; or they can be otherworldly realms that can only be reached through astral projection or Oneiromancy.  
  • 6) the otherworld and otherworlders: death is not final in Elyden. Following death a persons soul enters a gestative period of arbitrary length, with the spirit dwelling in a timeless astral plane known as the otherworld. This realm can be travelled to by some shapers, and is used for long-range communication. Amongst other things. Following this period the spirit is reborn as an otherworlder – an alien aloof being that returns to the material realm. Mortals claim these beings are considered as angels or demons, their purpose unknown, but thought to either aid or hinder mortals. The truth is unknown and though the varying breeds have been catalogued under strange taxonomies, they remain oddities of the otherworld, rare, despite it being accepted as fact that each spirit eventually becomes an otherworlder.
  • 7) Halfbloods: Some otherworlders can breed with mortals, leading to so-called halfbloods – beings with one foot in the material and another in the otherworld, belonging to neither. They appear alien and have strange wondrous abilities, that dilute with each generation. Some halfbloods have risen to positions of power, either ruling, or founding great hoses and dynasties that last millennia, inbreeding and seeking out otherworlders of their lineage to preserve their bloodline  
  • 8) Technology and Technarcana: The heart of Elyden is the Inner Sea, and the nations surrounding it are post-industrial. Aside from steam engines and other technologies common in the real world around the Victorian era, there is also technarcana – machines and engines that use the Atramenta and the Firmament to function. These can take the form of scrying pool, far-range communicators, body orthoses akin to power armour, iron-mantles surgically grafted to shapers backs to aid them in their shaping, and so on.
        With regards to real-world technologies, the main anachronism is the absence of trains (though there are electric trams in the larger cities). In their place are ambulants and conveyors – tracked vehicles that range from personal carriers and huge land-ships that crawl across the wastelands of the world. The printing press, steam mills, forges, photography, bicycles, single tracked motorbikes, primitive telegraphs metal-hulled steamships, rubber tyres, sewing machines, stainless steel, concrete, typewriters, repeating rifles and revolvers (but no machine guns), artillery, blimps (rare), electricity (relatively rare, only common in high-class districts of larger cities), phonograph & voice recordings.
        Notable absences include railways, radio, though technarcane replacements may exist, but not widespread.
  • 9) YEAR 4007 RM: the present day is 4007 RM (the Reign of Malichar)

I'll be adding more details over the coming days.

I've also made some maps, including the examples below:

Great Lakes Earth Map

In the event anyone asks--dark brown are the mountains, light brown are the resulting uplands and black are the original extent of flood basalt lava provinces visible today and with no consideration of erosion.

Let us say that, in the future, some scientists have created satellites capable of something that seems science fiction for now — punching the walls of the universe to study an alternate reality. By that scenario, some hundreds of “alternate Earths” from hundreds of alternate universes would already have been discovered and meticulously studied. As much as half of them would still be ruled by humans, unfolded by events that turned out differently. One universe, for example, had an Earth where 9/11 never happened, or where the outcome of the Revolutionary and Civil Wars ended up differently.

One of the most interesting to note was a planet that scientists call “Alternate Earth 111”, known to the public as “Great Lakes Earth”.

Because at first glance, it seemed that almost every continent is dominated by lakes, even those larger than the Great Lakes that we have in North America.

The Americas
The Appalachian Range used to exist, but all that remains nowadays are their metamorphic bedrocks. Since then, the Atlantic Coast is a labyrinth of islands, straits, channels and sounds, making New England the eastern equivalent of the Inside Passage, caused by five million years of being repeatedly scraped and bulldozed by ice. The terrain is not quite dramatic, the tallest above sea level being only 122.2 feet (37.25 meters.)

While our Rockies stand no taller than 14,440 feet above sea level, the tallest peak in a Great Lakes Rockies is measured to be 20,310 feet. Back home, our Rockies formed between 80 and 55 million years ago through the Laramide Orogeny, the subduction of the North American and Pacific plates at a shallow angle. Their Rockies first formed 55 million years ago as the result of a collision between eastern and western North America. They stopped becoming active as recently as nine million years ago. Since then, a series of faulting had shed off the mountains’ sedimentary skin and exposed the tougher granite-and-gneiss core. No wonder, then, that transdimensional explorer Mark Greene called the Great Lakes Earth Rockies “a single, continuous spine of breathtaking Tetons.” West of the Rockies stands an uplift varying in elevation above sea level between 2,000 and 13,000 feet (between 610 and 3962 meters.)

Minor differences in geological history could create major differences in geographical shape. Without the Cascades or the Alaska Range, the distinctively whiplike Alaskan Peninsula simply does not exist. The area we’d recognize as San Andreas (Baja Peninsula and southwestern California) is fused into what we’d call southeastern Alaska. Evidence in the rocks beneath the soil shows that San Andreas did indeed collide with Alaska only 24 million years ago, but the mountain-building period did not last long, and the peaks were reduced into quarter-mile-tall hills.

The Black Hills of South Dakota don’t exist on Great Lakes Earth. The Ozarks, larger in area and elevation than back home, are the closest analogy. The tallest stands 7242 feet (2207 meters) above sea level. They started life as a dome of granite that, over millions of years, had been replenished with fresh supplies of magma. This allowed the crystals that made the granite dramatically larger, making the rock itself a lot harder. After 2.2 billion years under the surface, the dome popped above sea level only as recently as 20 million years ago. Even though rain and river played a part in carving the dome into numerous spires, pillars and gorges, the real player in shaping the Ozarks is lower air pressure, exfoliating the surface into pieces like layers of onions.

True to the spirit of the planet’s name, North America is full of large lakes. The largest of which is Agassiz. In fact, it is the cornerstone of all of Great Lakes Earth’s great lakes — enormous depressions, tectonic rifts or volcanic calderas reshaped and filled in by ice, rain and river. To have an idea on the shape, size and scope of Agassiz, we must look at the familiar faces of the Great Lakes — Superior, Michigan, Huron, Erie and Ontario — and then flood off the entire basin. This is Lake Agassiz, 95,000 square miles and 5500 feet at its deepest. Agassiz started out as an impact crater 600 miles wide by an iron asteroid approximating 75 miles in diameter which slammed on that spot 230 million years ago. The crater, quickly filled up by basaltic lava, wouldn’t become a lake until the ice bulldozed the flood basalt away during the Pleistocene glaciations.

West of the Rockies, there are even more lakes—Bonneville, Carson, Olympia, Hamilton and Red Deer. All of them formed separately late during the Cenozoic as tectonic weaknesses sank the land, sometimes to the point below sea level. Further shaping the lakes were the last five million years of ice ages strengthening and weakening the freeze-thaw cycles. As a result, not only do they have their distinctive shapes, they are also deep. Bonneville, the deepest, is currently over a thousand feet deep.

What we’d presume to be the Brooks Range in northern Alaska actually isn’t. The Murchison Mountains, as we call them, are actually volcanic peaks standing 14,411 feet (4392 meters) above sea level at the tallest. They stand at one of the points where the Arctic Plate sinks beneath the Laurasian Plate.

The Yellowstone mantle plume is still present. Except that instead of Wyoming’s northwestern corner, it can be found in northeastern California. The upland itself covers an area of 5,000 square miles and stands almost like an island between the surrounding lakes and lowlands.

Five million years ago, the oceanic Panamanian Plate had been invaded on both fronts—by the Caribbean Plate in the northeast and the Pacific Plate in the southwest. This uplifted the basaltic slab to above sea level and had volcanoes guarding the plateau. The Twins, as they are called, are still active. One twin is currently 6,684 feet above sea level, the other 9,698 feet. Curiously, the Twins make up the coastline of Central America on Great Lakes Earth, which makes sense considering their young age. What doesn’t make sense is how they could be so tall in so short a time. The same problem is said of the Andes, which also make up South America’s entire western coastline. But if we look at a bathymetrical map, we start to understand why—from Argentina to Guatemala, the Pacific Plate is paralleled by the younger, narrower Nazca Plate. It first formed only ten million years ago and uplifted the Andean coastline for five million years before reaching the Panamanian Plate. This double-subduction may explain why the Andes, 25,122 feet above sea level and still rising, as they have been for the last 45 million years, had such devastating eruptions in the last 10,000 years, with an average of one eruption measuring eight on the VEI every thousand years.

Andean uplift notwithstanding, there is a transition between northern and southern South America—a transition separated by 2,891 feet of elevation. That is because from 250 to 200 million years ago, South America’s southern half was part of an uplifted plateau much like Tibet back home. The more recent uplift of the Andes nearly attempted to resurface that past.

Questions follow:

Are these changes enough to spare northeastern Nebraska from the onslaught of Tornado Alley without sacrificing the Midwest’s prairie fertility in the process?
Will all these lakes and rivers (not pictured) turn the Wild West into a greener Eden?
How much of the Amazon Basin will be contained within South America?
What kind of landscapes should I expect to see in Argentina and Brazil?

Physically absent in the supercontinent are Turkey, Iran, and the Low Countries (Belgium, Netherlands, Luxemburg and Denmark). Back home, Scandinavia is one of Earth’s recognizable peninsulas. On Great Lakes Earth, the body we’d recognize as the Baltic Sea is actually known as the Baltic Plain. It is all that’s left of a mountain-building process from 250 to 200 million years ago that connected Scandinavia to the rest of Europe.

Long ago, the British Isles used to be an extension of mainland Europe before splitting off 100 million years ago. Proof — the very shape of the sea that we back home would call the Low Countries.

The dominating feature of Asia is a large region of basaltic rock, the Siberian Traps. It formed as a series of eruptions spewed out lava 60 to 43 million years ago. Since most of northern Asia was a receding series of shallow seas at the time, the eruptions resulted in only two types of lava—pillow lava (underwater lava that is low in both gas and viscosity) and block lava (what could happen when lava that is high in viscosity but low on gas erupts underwater.) In time, as sea levels kept on receding, the lava eruptions shifted to columnar (like the Giant’s Causeway in Northern Ireland back home), lava-fountain and dome-building. Each eruption could last anywhere between 10,000 and 60,000 years, with breaks varying between 30,000 and 80,000 years. When the last eruption had finished, seven million square miles of Eurasia were buried under four million cubic miles of lava.

Eurasia is subject to Great Lakes Earth’s largest sea, one that we used to have back home — the Tethys. Back home, the Mediterranean has an average depth of 1500 meters and a maximum of 5267. The Tethys’ depth is 1205 meters on average and 7,000 maximum. Even so, the ratio between deep and shallow water is remarkably similar to that of the Mediterranean — more or less than 45% of the sea is no deeper than 200 meters (the required maximum depth for a sea to be “shallow”). It’s also connected to two oceans with two different personalities — the Indian to the east and the Atlantic to the west. What we’d recognize as the Arabian Peninsula is, on Great Lakes Earth, an extension of northeastern Africa, erasing both the Red Sea and the Gulf of Aden out of existence. This further widens the passage from the Indian Ocean to the Tethys.

The island of Newfoundland is the southeastern extension of Iceland. It stands at a point where a stationary mantle plume, loaded with silicon, stands at a crossroads between the Mid-Atlantic Ridge and the edge of the Arctic Plate. Unlike our Iceland, in which the Ridge has split it in east-west, the Iceland of Great Lakes Earth is split in a north-south division.

In Asia, what looks to us like Borneo is a big extension of eastern India, erasing the Bay of Bengal from the map. Sumatra is an extension of India’s western coast. The rest of Indonesia, as well as the island chain of the Philippines and the Malay Peninsula, don’t exist.

Back home, the Himalayan range in Asia is impressive enough. On Great Lakes Earth, they are even more so. The highest peak, Kailash, stands 33,500 feet (10,210.8 meters) above sea level and still rising. If the base of Mauna Kea in Hawaii were above sea level, this would have been its equal. Their Himalayas are older than ours, if the differences in height suggest anything. Ours first formed 50 million years ago. Theirs rose from the plains between 65 and 70 million years ago.

65 million years ago, sub-Himalayan Asia was subject to a series of lava eruptions lasting a total of 30,000 years. When it was all over, the lava covered a thickness exceeding one mile, an area of one-and-a-half million square miles and a volume greater than one million cubic miles.

The islands of Japan on Great Lakes Earth are the result of subductive hot spots, stationary mantle plumes standing in the intersections of colliding plates, as well as a confusing labyrinth of fault lines. Japan, consisting of six large hotspots, stands three miles southeast of the Laurasian Plate and five northwest of the Pacific Plate. The fact that the mountains make up the coastlines suggest that Japan on Great Lakes Earth formed very recently—no longer, it’s been surmised, than 11 million years. Like the Andes, Japan was subject to massive, earth-destroying eruptions.

The Alps remain tall, as they are back home. However, they are formed as the result of a piece of Africa, known to us as Balk, colliding with southeastern Europe 40 million years ago. Currently, the range’s highest peak, Olympus, stands 22,838 feet (6961 meters) above sea level and is still rising. Behind the Alps is a plateau that covers lands we’d recognize as Romania, Moldova, Slovenia, Austria, Slovakia and Hungary. Also, Balk’s terrain on Great Lakes Earth consists of plains and hills rather than mountain ranges like back home.

The Scandes, stretching the length of the northern Scandinavian coast, are the results of ocean/continent collisions — volcanoes. They are also taller than they are back home — 18,510 feet (5642 meters) above sea level and still rising.

The Ural, Caucasus, Pyrenees and Apennine mountain chains used to exist on Great Lakes Earth, but not anymore.

Questions follow:

With open connections to both the Indian and the Atlantic, what would the Tethys’s personality be?
Will a higher Himalayas — which means a higher Tibetan Plateau — pose any noticeable differences on India’s climate and precipitation, as well as Tibet's ecosystem?
Would adding Borneo and Sumatra pose any difference to the climate and landscape of the Indian subcontinent?
With the rest of Indonesia, the Philippines and the Malay Peninsula out of existence, how would this absence affect ocean currents?
How would all this added water affect the Mediterranean Basin as well as the Indian monsoon?
Concerning the Siberian Traps, 40 million years of erosion would mean an altogether different Russian landscape, no doubt, but to what extent? Would we still see vast, singular bands of boreal forests and steppes, or would we expect to see Russia hosting a wider variety of habitats?
Would a larger Deccan Traps pose any difference to the 65 million years of erosion?
How would the changes in mountain building and coastlining affect the climate and landscape of the rest of Europe?

To the naked eye, you may not see any difference between our Africa and theirs. However, like some of the other continents, Africa has its share of great lakes — Chad, Congo and Makgadikgadi. Lake Makgadikgadi, the southernmost, is also the youngest—100 feet (30 meters) at the deepest and formed as water flowing from the Aden Bahçesi inundated a series of fault lines only three million years ago.

The Atlas Mountains used to exist on Great Lakes Earth, but not anymore.

The defining mountain range of Africa is the Aden Bahçesi, which first formed 45 million years ago as the Indian Plate sank beneath the African Plate. Currently, the tallest peak stands 21,810 feet (6647.7 meters) above sea level and still rising.

Lakes Chad and Congo had a shared history. They originated less than 200 million years ago as a series of horsts and grabens that would quickly be inundated aftewards. It wasn’t until 80 million years ago, when the seafloor slowed down and sea levels began to recede, that perhaps the deepest points on Great Lakes Earth during the Cretaceous period, became surrounded by dry land. In time, freshwater diluted the lakes, pushing the salinity deeper and deeper. Today, Lake Congo to the south is 5387 feet at the deepest, the bottom 150 feet being brine. Lake Chad to the north has a maximum depth of 4820 feet, with the Pharaoh’s Brine taking up the bottom 67 feet.

Questions follow:

Are any of these changes enough to turn North and South Africa from desert to more verdant habitat, like savanna?
Would having a tropical megalake be enough to pose a noticeable difference to the equatorial climate of the Congo rainforest?

First and foremost, it’s not called “Australia” in Great Lakes Earth, but rather “Sahul”. The first major difference is the presence of Lake Eyre, a body of fresh water over 460,000 square miles in area and 49 meters at the deepest.

The northern and eastern coasts of Sahul are worth noticing. To the northwest, it looks as though the two main islands of New Zealand are glued into the mainland. It’d also look as though someone were shoving the island of New Guinea down the throat of mainland Australia, known geographically as the Gulf of Carpentaria. The northern and eastern extremes of Sahul are defined by volcanic mountains, the tallest standing 18,500 feet above sea level.

The final difference is that Sahul is much further south than Australia. So much so, in fact, that by comparison, the distance between it and Antarctica is cut by half.

Questions follow:

Will the Outback still be desert?
In the same scenario, Indonesia and the Philippines don’t exist. What kind of ocean current(s) would one expect to see influencing Sahul?
What kind of climatic and ecological influences would we expect Lake Eyre and the continent’s closer proximity to Antarctica to create?

Pole to Pole
Compared to our oceans, the Arctic Ocean of Great Lakes Earth seems to have a little elbow room. The reason — the Atlantic on Great Lakes Earth is wider than ours by over 1350 miles. Africa, Eurasia and Sahul have, compared to our Old World, moved that far eastward, creating a landbridge that connects Asia to North America, erasing the Bering Strait off the map and shrinking the Bering Sea. To that extent, it would be like turning the Russian urban locality of Egvekinot (66.3205 degrees North and 179.1184 degrees West) into the next-door neighbor of Teller, Alaska. But that is in our eyes only. On Great Lakes Earth, North America has always been a part of Laurasia for 250 million years.

The island of Greenland looks, to us, rearranged to the extent that Mont Forel, the island’s highest peak, is located in 90 degrees North — the North Geographic Pole.

There is a final difference, one that applies also to the Southern Ocean surrounding Antarctica. The ratio between average depth and maximum depth is the same as back home, but the numbers are different. Back home, the Arctic’s average depth is only 1205 meters, almost 4,000 feet, whereas its deepest point is 5,625 meters, 18,456 feet. The Southern Ocean averages 4,000 meters deep and has a maximum depth of 7,235. On Great Lakes Earth, the averages for the Arctic and Antarctic oceans are 1652 and 5280 meters, respectively.

Then, of course, there is the Arctic Plate, something that doesn’t exist back home. Horizontally cutting Iceland in half, we can find the border straddling the coasts of Baffin Island, Alaska, and Scandinavia, creating the Scandes and the Murchison mountains.

Questions follow:

How would these differences affect ocean currents and polar landscapes?
Could any of these changes have influenced the global average temperature and precipitation? If so, to what extent?

Ocean Deep
Back home, the Pacific Ocean, the largest of the five, has an average depth of 4028 meters, 15,215 feet, and a maximum of 10,924 meters, 35,840 feet. On Great Lakes Earth, the Pacific’s depth averages 3854 meters — 12,644 feet — and the maximum is now 7455 meters, 24,459 feet.

Back home, the Indian Ocean averages around 3963 meters deep with a maximum depth of 7258. That’s 13,002 and 23,812 feet, respectively. On Great Lakes Earth, the Indian Ocean averages around 3605 meters (11,827 feet) deep and has a maximum depth of 5625 meters (18,454 feet).

The Atlantic Ocean back home has an average depth of 3926 meters, or 10,950 feet and a maximum of 8605 meters, 28,320 feet. On Great Lakes Earth, its average depth is now 4001 meters (13,126 feet), and the maximum is now 7455 meters, the same as the Pacific.

Questions follow:
Would the changes in depth affect ocean currents, therefore the global climate?
