A hulking creature with four legs and three arms, a Hruul is a formidable foe. Standing 18 feet tall on average, muscles standing out like fleshy boulders, and wielding a giant stone axe in one hand with a club in another, there are few who would dare to stand their ground when attacked. It is not known if it possesses the faculty of language, but a hruul is known to shake saplings with the terrible roars that issue from its sharp-toothed mouth.

There seems to be a crude form of hierarchy among groups of hruul, though exactly how it functions is not unknown; however, it is clear that the larger the hruul, the more deference it is given by its kind and that they are sometimes seen cooperating in coordinated ways.
