The only notable characteristic of Twilight world is it's remarkable averageness. This averageness has made it a perfect home for a unique diversity of intelligent races on its four continents: Amet, Hadira, Xi'lan and Gashuk. Many of the peoples living on Twilight world like the Elves and Dragonborn are not native. These circumstances have created a perfect environment for strife, unlikely alliances and more than its fair share of divine meddling. The culmination of said meddling being Nightfall resulting in The Reckoning. Post reckoning the remains of Areth's army made a deal with The Circle of Kiral giving them a new home on Amet, over the following centuries they were joined by refugees Xi'lan and formed the great metropolis New Amet. The invention of the Spelljammers heralded The Diaspora from the crowded world as the High Elves and Drow have already departed completely along with many smaller groups of pioneers from other races. Many other larger groups and races are making preparations to leave as soon as they find a new habitable world.
