Yugoloth

Yugoloths are fickle fiends that inhabit the planes of Acheron, Gehenna, Hades, and Carceri. They act as mercenaries and are notorious for their shifting loyalties. They are the embodiments of avarice. Before serving under anyone’s banner, a yugoloth asks the only question on its mind: What’s in it for me?
Spawn of Gehenna. The first yugoloths were created by a sisterhood of night hags on Gehenna. It is widely believed that Asmodeus, Lord of the Nine Hells, commissioned the work, in the hope of creating an army of fiends that were not bound to the Nine Hells. In the course of making this new army, the hags crafted four magic tomes and recorded the true names of every yugoloth they created, save one, the General of Gehenna. These tomes were called the Books of Keeping. Since knowing a fiend’s true name grants power over it, the hags used the books to ensure the yugoloths’ loyalty. They also used the books to capture the true names of other fiends that crossed them. It is rumored that the Books of Keeping contain the true names of a few demon lords and archdevils as well.
Petty jealousies and endless bickering caused the sisterhood to dissolve, and in the ensuing power grab, the Books of Keeping were lost or stolen. No longer indentured to anyone, the yugoloths gained independence, and they now offer their services to the highest bidder.
Fiendish Mercenaries. Summoned yugoloths demand much for their time and loyalty. Whatever promises a yugoloth makes are quickly broken when a better opportunity presents itself. Unlike demons, yugoloths can be reasoned with, but unlike devils, they are rarely true to their word.
Yugoloths can be found anywhere, but the high cost of maintaining a yugoloth army’s loyalty typically exceeds what any warlord on the Material Plane can pay.
Being self-serving creatures, yugoloths quarrel among themselves constantly. A yugoloth army is more organized than a ravening horde of demons, but far less orderly and regimented than a legion of devils. Without a powerful leader to keep them in line, yugoloths fight simply to indulge their violent predilections, and only as long as it benefits them to do so.
Back to Gehenna. When a yugoloth dies, it dissolves into a pool of ichor and reforms at full strength on the Bleak Eternity of Gehenna. Only on its native plane can a yugoloth be destroyed permanently. A yugoloth knows this and acts accordingly. When summoned to other planes, a yugoloth fights without concern for its own well-being. On Gehenna, it is more apt to retreat or plead for mercy if its demise seems imminent.
When a yugoloth is permanently destroyed, its name vanishes from every Book of Keeping. If a yugoloth is re-created by way of an unholy ritual requiring the expenditure of souls, its name reappears in the books.

The Books of Keeping.
When all four copies of the Books of Keeping disappeared, Asmodeus and the night hags lost control of their yugoloth creations. Each Book of Keeping still exists, drifting from plane to plane, where the brave and the foolish occasionally stumble upon them.
A yugoloth summoned using its true name, as inscribed in the Books of Keeping, is forced to serve its summoner obediently. The yugoloth hates being controlled in this manner and isn’t shy about making its displeasure known. Like a petulant child, it will follow its instructions to the letter while looking for opportunities to misinterpret them.
