Medium Aberration (Kobold) Fighter 3
Tazex the Everchanging was King of the Kobolds, leading his tribe to perform many raids against local caravans and merchants. Somehow, he ended up heavily mutated, being larger than normal, having four arms, and possessing the ability to breathe fire. The party defeated him, but he melted through the floor, and so may be back some day. He held Idruma for ransom, placing him in one of the cells.
He eventually returned as the Red Talon for the final battle, hoping to finally get revenge on the scales and recover his crown. He was defeated, and his death provided a clue as to the identity of Klorphaxius/Malevictus.
