Aasim is large for a human standing several inches taller than 6 feet, and of stocky build. Of course, he isn't actually human, having blue hair, blue eyes, and blue skin. And his hair seems to move in the wind, even when the air is dead calm.

He wears hard wearing clothing with a pouch and  dagger at his belt, and often has a spear he uses for a walking stick, but doesn't seem to own any other possessions, other than the odd bit of jewelry.
