The Sorcerer-Kax-Agi the Burning Gold

Despite the many sorcerers that exist in Ku'Eza, there is one man of mysterious power known only as The Sorcerer. He is mentioned in historical text, religious script, and even children's stories. There are many small villages and towns that say they've had contact with someone who uses that moniker. He is always described as either a wonderful helper, a quiet hero, or pleasantly terrifying. The strangest thing about this mystery man though, is that no one can remember what he looks like.
The Sorcerer is one of the original 8 Kohsen, though he lives with this truth hidden from the world. He doesn't much care for many of his siblings, believing that those whose names now hold reverence carry too much risk of becoming divine. He avoids their annual gatherings as often as he can, much to their ire.
