Keowik Okolaye is a mage who, like many such in Graypool, draws on the energies of nature for much of his power. He puts this power, however, to an unusual use: Okolaye specializes in replacing limbs and parts of the body with substitutions made from natural materials. He offers this service to others, for suitable payment, operating out of a storefront made to look like a tree stump. While he can replace perfectly healthy organs, more often he is called upon to provide prosthetics for limbs that have been badly damaged or severed. His fees are comparable, if not less, than would be typically charged to regenerate missing parts, and his methods offer certain advantages, most notably that the magical proshetic can easily be enchanted with additional powers—though Okolaye does charge extra for that. By default, the prosthetics look like the constructions they are, made of stone or wood or whatever other materials he chooses to use, but—again for an additional fee—he can mold and color the prosthetics to look almost human if his customers so desire.

In fact, Okolaye can replace more than individual parts. He can transfer people's souls into whole new artificial bodies, made of the same materials as he uses for prosthetic limbs, and with the same advantages and drawbacks. Generally he is asked to do this only for those who are mortally wounded or terminally ill, but if a perfectly healthy person wants to get an artificial body, he has no reason to deny them. In fact, Okolaye himself inhabits just such an artificial body. Most of his body he has modeled to look like his former fleshy body did, albeit much younger than that body would now have been, but the limbs and eyes are (intentional) giveaways... and in particular the extra arms he's decided to give himself.

Keowik Okolaye is—or was, and currently mostly appears to be—a compact young man with light red-brown skin and long, black hair. He has a broad nose with an almost semicircular profile and round cheeks that he often puffs even rounder when he's exerting himself. His most distinctive features are his four arms, none shaped quite like a human arm and each clearly of a different material, and his odd eyes, with metallic gold irises and light green corneas that glow in the dark. Okoloye has a clear and somewhat deep voice and often hums to himself, or even sings under his breath when he's not in the middle of a conversation. Except on formal occasions, he seldom wears more than a soft leather kilt and sandals.
