An old planet with life; in its current geological epoch, almost all of its continental plates have sunken down below the surface of its oceans, leaving behind scattered, isolated rocks that were once great mountaintops, and three defiant plates that still remain at least somewhat surfaced.The Lowlands-
an expansive region of great plains and open prairie with some scattered coastal and montane temperate forests - it is the most widespread region on the Mainland. It is the home region of Sinking World's only sapient species and is inhabited by a number of agrarian cultures.The Midlands-
a mixed region of mountainous terrain and lush river-valleys, while Sinking's World only sapient species originated in the Lowlands, it does not rule from there. The Midlands is the home of a number of advanced industrial cultures, capable of extensive maritime exploration.The Highlands-
a region of labyrinthine foothills and low mountain ranges, the Highlands is home to a number of agrarian and hunter-gatherer warrior cultures which remain isolated from the rest of the Mainland. It is guarded against the rest of the continent by the 'Great Squid' - a mountain range named as such because, starting from its base in the Lowlands, when viewed from high above the world, it appears to be a great squid with protruding tentacles, and is spewing forth a great volume of ink.The Hinterlands-
A cluster of uninhabited islands, the wildlife of the Hinterlands is very alien to that of the Mainland, as it has been separated from life on the primary continent for somewhere around 200-400 million years without any contact. The Hinterlands is actually the highest point of a great submerged landmass, and its study by Mainlandic naturalists from a variety of universities is cause for great, almost continuous scientific breakthrough.Old Nook-
An extremely isolated, lush, intimidating tropical island, 'Old Nook' was first recorded by famous maritime explorer Cosrius the Brave but was discarded as a fable until a lost Imperial fleet - blown into the Great Expanse by a cyclone - returned to the Mainland with official documentation and specimens as evidence of the expedition. The sailors reported a jungle rich in truly otherworldly plants and animals and vast cyclopean ruins, forbiddingly ancient, made from an oily black stone - vast in scale, and overgrown with plant and animal life - left behind by an unimaginably ancient civilization; probably older than any mountain, older than the Mainland's native intelligence itself. A disturbing thought. As an old 'nook' or 'cranny' from an ancient, truly otherworldly landmass lost to the waves, multiple attempts after its rediscovery were made to rediscover Old Nook - only a handful of which has returned in success, while many of which haven't returned at all, leading to a theory that Old Nook actually rapidly shifts positions out in the Great Expanse by anomalous means.The Great Expanse-
the general name for the vast, unbroken expanse of salt water surrounding the few refuges of terrestrial life left on Sinking World. Those unfortunate or foolhardy enough to venture out into the Expanse either receive the nickname 'the Brave' or 'the Foolish' depending on whether or not they simply return. The Great Expanse is not the realm for sailors and ships; it is the realm of ancient, colossal sea monsters - eons-old - vast sea serpents, giant squid, and other marine behemoths that eventually consume all that stray too far from the sight of land...
This is a random map of an odd world I worked on for personal amusement; I actually started working on it back in 14 November, 2017. I'll admit, in hindsight, this post looks pretty barren.
I may work on fixing that.
