The Nightlands

The sun has been gone for centuries. Most of the species who live here have lost all record of their past before the Nightfall. Light only comes once every five turns in the form of the aurora-like Upper Lights. Only the screaming, possibly living energy clouds nicknamed banshees keep the ocean from freezing over. Glowing crystals sprout from the ground. Ruins appear and disappear from the ever-shifting landscape. The omnipresent flow of magic has left many areas twisted, alien, or just skirting around what should be the laws of physics. The earth and seas only provide a shallow barrier from the endless void. Eldritchly powerful Elder Beasts stalk the world, returning in new and even stronger forms whenever they are killed. And something even greater may soon awaken.
And yet, life goes on.
