Gor

The most common type of Beastman is the Gor. Large, powerful, and numerous, they form the spine of any herd. Whilst their appearance varies a great deal, all combine some bestial features with those of a man. It’s the horns that all Gors have that separate them from lesser Beastmen. Horns are the ultimate signs of rank and power, and their leaders always have the largest and most spectacular horns, which they always paint with blood, dung, or dyes to strike fear in the hearts of their enemies.

Though Gors are taken as a whole breed in themselves, they are creatures of Chaos and prone to a wide variety of mutations. Some Gors have the head of an insect or even a horse, an abundance of limbs, lashing tails, and just about any other hideous combination. Still, there are three major categories of Gors that bear mentioning.

Bovigors
Bovigors are those Gors who have cattle horns on their head and may have the entire head of a bull or ox. Bovigors are highly competitive and see themselves as superior to all other Gors. Most have little use for thinking, preferring instead to use their mighty strength to solve problems.

Caprigors
More common than all other types of Gors, Caprigors have curling or straight horns on their head, like a goat or ram. Most Caprigors may have the entire head of a goat, and if so, they also have matching goat legs.

Truegors
A Beastman that has fine horns and no other mutations is called a Truegor. Truegors have either Human or goat legs. These rare Beastmen are the most intelligent and strongest of all of their kind, almost always rising to positions of great honour within the herd.
