Celotene

Celotene, or Crucible as it was called centuries ago, used to be a land ringed by mountains, with the land in between being completely flat metallic slabs. Before Recondite settlers, this land used to have regular sunlight, though rainclouds could never quite climb over the mountain ranges. The recondite settlers found a way in through the mountains and built their cities on the southern point of this land. Their secondary city, Bemons, they built into the southern mountain range, to mine the ore there and to search for something as ordered by the Council. In normal circumstances, or if settled by any other people, this settlement couldn't have been able to thrive, but the recondites are an ingenious lot. They built great magical crystals, called Aeternalith and Vitalith, to sustain their bodies indefinitely and to sustain any imported wildlife likewise. The downside to these contraptions was a great black smog that rose to the sky, unable to escape the cage of mountains surrounding it, that eventually blackened the Sun and coveved this land in perpetual darkness. From this the land derives its name, Celotene, meaning "Dark Skies" in their arcane tongue.    The Recondites expanded slowly through the centuries, growing their imported forests and mining ever deeper into the Stagnates mountain range, until one fateful day Bemons disappeared, finally found some months later on the northern end of the continent with its people slaughtered, and the unfortunate disaster known as the "Aeternalith Disaster" changed this place again forever. The great crystals that granted the Recondites immortality, sabotaged it is said, are broken as is the smog that covered the land for centuries. Sun shines on Celotene again.
