Yugoloth

A type of fiends native to the Blood Rift. They were neutral in the affairs of the other fiendish races, interfering only when they saw a situation that might be profitable or a potential for the advancement of their own schemes.

The yugoloths were manipulative, secretive, and mercenary by nature, often acting as soldiers for deities in their own private wars, or even at times aiding both sides of the Blood War.
