Tiamat

Tiamat is the name of a powerful draconic goddess in the Dungeons & Dragons role-playing game . The name is taken from Tiamat, a goddess in ancient Mesopotamian mythology who is substantially different (and does not have multiple heads).

Tiamat is a queen and mother of evil dragons and a member of the default pantheon of D&D gods . Tiamat was also named as one of the greatest villains in D&D history in Dragon #359, the magazine's final print issue.

She was given the name Tiamat after the dragonlike Babylonian goddess of the salt waters.

The character was introduced to the game in its first supplement, Greyhawk (1975), by Gary Gygax and Rob Kuntz. In this book, she was only known as "the Dragon Queen" and "the Chromatic Dragon." She was described as she is now, but she did not yet have a personal name.
