Dragon
An extremely large, powerful, winged reptilian creature. Long-lived and intelligent, they come in two general varieties, the good metallic and the evil chromatic. Dragons typically live in isolated areas and keep vast hordes of treasure.
About 600 years ago, the dragon gods Tiamat and Bahamut reached an accord, ending the conflict and division between dragons and allowing all of them, along with most dragon-kin and dragon-related beings, to transcend into a higher reality, leaving the multiverse forver. Nowadays, they are considered myths and children's stories.
