Korrick is hot-tempered, quickly aroused to anger, though he is usually a "merrier sort", according to Aurora.
As centaur is a broad-chested man, shirtless and bearded, heavy-browed and fierce-looking with heavy and equine forelegs. He had Clydesdale-sized hooves.
As a unicorn, he looked like a Budweiser horse, he was about eighteen hands high, maybe more. he had a broad chest, four heavy hooves, forward-pricked ears, and a long equine face. he didn’t have a coat. he just had a smooth and slick-looking carapace, all chitinous scales and plates, mixing colors of dark green and midnight black. The hooves were cloven and one spiraling horn rose from its forehead, three feet long and wickedly pointed. The spirals were serrated on the edges, some of them covered with rust-brown stains. A pair of curling bighorn sheep looking horns, curved around the sides of his head from the base of the horn. Seemingly eyeless, instead leathery chitin where they should have been, and his mane was of rotted cobwebs.
