Soul Broker

Soul brokers are demons in disguise that wander the mortal realm looking to make deals with mortals for their souls. They approach the desperate and grieving with propositions to save their dying friends and family, or grant them great wealth or skill. Once a deal is made, a contract is signed and can never be undone unless the broker literally eats the contract itself.

The contract is written in an ancient demonic language, and with special ink that comes from the nine hells, over a predetermined amount of time the ink transfers directly to special contract in the demonic vaults, so once the ink on the written contract disappears, the contract is complete and the soul is claimed.

The brokers themselves used to be mortals, usually dabblers in dark arts and shady merchants who begin to deal in morally volatile goods. Most soul brokers are trying to buy or bargain themselves out of their own troubles with the underworld. They operate with minimal power borrowed from great Demon lords of the Nine Hells, who value souls more than anything.

If the broker ever does eat one of their contract, they gain further debt to their patron demon lord, thus they will usually only do so under threat of death which would hasten them to their eternal punishment as a lowly demon under their lord's brutal reign.
