Tiamat

Appearance
Tiamat is a massive dragon with five heads, each head is the color of a chromatic dragon and has all of the powers of one of their kind.

Her hide is multicolored, with aspects of each of the chromatic dragons, and her tail is tipped with a venomous stinger reminiscent of a wyvern.

History
According to legend, Tiamat and Bahamut were the first children of the World-Shaper Io. Like her brother, she is one of the oldest creatures in existence.

Dogma
Tiamat is an unforgiving goddess, inciting her followers to spread evil and worship her evil children. The lesser races are all subservient to dragonkind and must pay homage, respect and worship to her.

Relationships
Tiamat loathes her brother Bahamut and nothing gives her greater joy than the destruction of his champions.
