Kobold
Kobolds are reptilian humanoids that worship and serve Dragons, considering them demigods. Kobolds inhabit Dragon's lairs when they can, but more commonly can be found in dungeons, gathering treasures and trinkets to add to their own tiny hoards.
A few Kobolds are born with leathery wings and can fly. Known as urds, they like to lurk on high ledges and drop rocks on passersby. Although the urds' wings are seen as gifts from Tiamat, the Dragon Queen, wingless Kobolds are envious of those gifts and don't get along with the urds.
