Rrask is a brutish-looking thri-kreen of a sandy complexion and imposing stature. His powerful limbs and sharp claws lend themselves to an intimidating predatory image as he stalks the land on his stilt-like legs. Despite his size, Rrask moves with alarming purpose and grace and his graspers can quickly find purchase at alarming speeds like the praying mantis he resembles.

His large, glassy eyes seem to carry a raptorial glint, but his disposition is rather difficult to gauge on a surface level. His insectoid face seems to twitch and jolt at random directions, and when spoken to he seems either unwilling or incapable of talking.
