Stolas is an anthropomorphic owl demon. He is tall and slender, with a white, heart-shaped facial disk and small black beak, resembling that of an owl. He has two pairs of almond-shaped red eyes, one set atop the other, with no visible irises or pupils, albeit white highlights do occasionally appear when he is excited. Stolas gives the immediate impression of someone regal and ostentatious, as would be expected for a royal of his station. He dresses in clothing befitting his role.
