Cyclops of the Labyrinth, also called the Demonic Jailer, is a demonic guardian of the Omniporal Labyrinth. Its red eye radiates a weakening energy, and it carries a whip of dark energy with which it chains its prey. Its body resists nonmagical damage.
The group defeated it during the first incursion into the Labyrinth. After its fall, the refugees it held captive were freed and led to the exit thread; some recognized their rescuers.
