The Aptorian demon is a creature from the Shadow Realm described in the Malazan Empire series of books by Steven Erikson. It is a three legged demon, with a massive fasceted eye, and this is my take on it. Kalam is also a central character that features in many of the books, and notably has a story arc with the Aptorian demon.
This is a tiny pencil sketch, when I say tiny, it's about 2 inches across, which I made in the margin of a notebook sometime in 2013. For once it scanned better than the sketch actually looks, it has not been modified in any way other than a slight contrast increase.
