Brutes

Every army needs its seige weapons, every city needs its heavy construction units. In infernus, these are the Brutes.  8 foot tall creatures of muscle and bone, of sharp protrusions and horn, these very intelligent beings are kept in check by a loyalty inherent to their kind.
To mistreat a Brute is a massive faux pas, and likely to result in grevous injury to the person in question. 
With intelligence and strength on their side, it is their low numbers, slow breeding cycles and extreme fragility as young that stop them from becoming the ruling class of demon in Infernus.

Brutes in Levis

Due to Xylos' invasion in (date tbd) and then the second invasion in (at least 2 generations later), there exist 6 Brutes on the Levis side of the realms. While one of the Brutes has become warlord of a raiding party in the south of the Forbidden Forest, a second retreating into the mountains to the east of Natare, 4 of the Brutes remain unaccounted for, which is a surprising development for beings so large.
