Nakrah

Nakrah is a member of a group of dragons called the First Brood. These were the first dragons created by the gods and were not held by strict classifications like metallic or chromatic.
While Tiamat allied herself with the devils, and Bahamut with the heavens Nakrah refused to fight her brethren at all. She instead retreated to the isle of Koier and slept. She woke when the Nine set foot on Andorra, but kept her existence hidden until the Saints of the Wyrd found her. She had a soft spot for the Penyu, who would sometimes be swept unto her shores, leaving their eggs there before passing on.
Nakrah is associated with the astral plane, especially Sigil where she has resided since the War of Ascension. She values knowledge and balance above all things.
