The Adan'f is a reptilian race similar to the S'Kra Mur. They were created by the Dragon Priests out of the Shalswar, and because of this they worship the Dragon Priests as gods. They are cursed by the Immortals because of their artificial creation. Adan'f wear armor, carry weapons, and some even cast spells. Their home is in the Whistling Woods and Ice Caves out the south gate of Shard, and their curse prevents them from leaving the general vicinity of this area for extended periods.
