Fighting Fire with Fire
The characters are taken to meet DreadEye to formalize their service to Malal. There were no contracts signed in blood. DreadEye ChaosVexer merely took them at their word. Though “WORDS” have their own power.
DreadEye is a greater Deamon. He was once a human that served Malal so well that when he died he was allowed to accend to Malal’s plane and was granted much greater power. The monolith they visited summarized his service to his lord.
