Mask
Sereno Blackwood looks like a fairly normal (okay, if a bit scrawny and geeky) Latino in his early 20s, dressed in fairly casual attire, always with black slacks (never jeans) and a colored shirt that looks halfway decent with the stupidly frilly yellow apron he wears while cleaning. Short, messy, black hair that is just gelled enough to give it a bit of character, olive skin, with a kind pair of eyes, the right brown, the left a bright green, like springtime grass.

As a Wizened, Sereno looks on the verge of exhaustion, the shadows on his face made more extreme and his skin the color of very aged parchment. His hair takes on the sheen of ink as well, and he looks sickly, starved. Still, his eyes are warm and friendly, with a spark in the green eye and those with a nose can recognize the smell of wood pulp and budding flowers around him, even when he tries to hide it with cologne.
