Hordebreaker

Many folk of the Silver Marches harbor a special hatred for the tribes and hordes of humanoids that constantly threaten to destroy the civilized way of life in this region. This antipathy is so great for some that it borders on paranoid obsession, and these folk sometimes swear enmity against one or more races of humanoids that gather in large groups—specially those that gather in the mountain hordes. In the opinion of these fanatics, there is no greater danger facing the world than the ever-growing humanoid horde menace, and they believe it’s up to them to fight it. 
The hordebreaker is a person who makes destroying the horde threat her life’s work. She trains long and hard to make herself the perfect engine of orc destruction. Often such individuals have suffered personal losses at the hands of humanoid hordes. Whatever the motivation, the hordebreaker’s mission to destroy orcs and other such creatures is her reason for living.
Most hordebreakers are barbarians, and many of them hail from those Uthgardt tribes that consider the orcs their traditional enemies, particularly the Sky Pony tribe. They sometimes work with other hordebreakers, but they tend to be loners: A life of singleminded hatred is not well suited to close companionship. Some hordebreakers attach themselves to adventuring parties if such groups are likely to encounter orcs or are engaged on a mission that will undermine an orc horde’s plans.
