The Opawang appears to be a normal man of middle years with a waxy, almost translucent complexion. Muscles and bones can be seen beneath the skin in bright light, and the Opawang's eyes glow with an unearthly radiance when he is angry (similar to the wu jen fiery eyes spell--and with the same effect).
The Opawang also has absolute control over the spirits, greater and lesser on the island of Akari. He holds the spirit of the island itself, Harooga, prisoner in his Dead Land domain. All spirits on the island of Akari are uncooperative to those other than the Opawang and his Ochimo (who are referred to as a single being). This is by command of the Opawang.
