Jarells are large humanoids with great strength. They have mottled skin, which is predominantly purple and white, but include blue patches on the arms and forehead. Cranial ridges are present on their heads, starting at the brow and running over the scalp to the back of their heads. Instead of a mouth, Jarells possess multi-tentacled mouthparts. Several small bony growths sprout on their elbows, and their fingers terminate in sharp claws.
