Grilgrimm is tall and thin with long black hair, brown eyes, a thin face and crooked nose. He tends to adorn himself with warg fur and studded leather. He is a master archer, though at close range he prefers to use a dirk.
Grilgrimm is a very quiet ranger from Uur-bek, who is friends with Doc, Rombour and Skyrlandus. Not much of his backstory is known, as he prefers to stay silent most of the time.
