He appears as a tall tiefling whose body is composed partly of living smoke and partly of carved ebony flesh. The smoke moves like slow waves across his shoulders and coils into shapes that sometimes resolve into dreadlocks of vapor. His emerald eyes gleam as if set in glass, and thin tendrils of green smoke curl from his nostrils whenever he smiles. His bloodshot sclera contrast with the calm, knowing light in his pupils. When he walks, each footstep leaves a faint ring of ash that fades after a few heartbeats. Unexpectedly, when he stands perfectly still the smoke briefly condenses into the silhouette of a small goat that then dissipates.
