Armanite

Armanites were a form of demon that raced across the blasted fields of the Abyss. They relished destruction.

The first armanites were centaurs that had stumbled upon a portal to the Abyss. After time spent in the realm of demons, they abandoned their proud heritage, taking up lives as abyssal mercenaries and being transformed into demons.

Known Armanites
The demon lord Graz'zt was known to employ a group of eight armanites - four white and four black ones - to draw his carriage.
