Rifts: How the New West Was Won.
The Blood axes are the Orc/Goblin/ugly other D-Bee gang, the more street toughs than anything. they like to extort money from pretty humans. They are the rebel gang, and pretty much are filled with non-humans. As you might guess axes are a favourite weapon, and a bloody hatchet is their normal warning of trouble or war. They tend towards to Black leathers with crossed blood axes painted on.
