Keres is a 5'10" man in his mid to late twenties. His blonde wavy hair sits in that style where you can't be sure if it's been carefully manicured to look messy, or if he rolled out of bed and left it how he found it. His eyes are dark, and seem to be constantly and intently watching his surroundings.

He is usually found well-dressed in pants and shirts that are tailored to his slim figure. More often than not he wears the same black, double-breasted trench coat, with a fur-lined hood sitting on his shoulders. At first glance the buttons appear to be faux ivory, but on closer inspection reveal themselves in fact to be bone. From what kind of animal, though, is unclear.

On his left ring finger sits an elegant diamond ring, not the style usually worn by a man. During times of stress or intense thought, he is often seen fiddling absent-mindedly with it.

His Immediate Nimbus draws the colour out of the world around him, leaving it in a bleak greyscale. His Signature Nimbus gives off a smell of lingering rust that cloys to the back of the throat, while unintelligible whispers can be heard just behind the ear.
