This young half-elf carries himself with purpose and will. He's well-built, the result of years of training and discipline. His firey red hair grows long, and he usually has a faint stubble to go with it. His armor and the lengthy blade he carries with him are always well kept, though with minimal decoration.
(To avoid a long list of lights for now I'll simply say Cas is bi, though prefers women, and a switch.)
