Corrupted Custodian

Franklin 'Frank' Miller had been Bingham Creek High's custodian for twenty-three years when he discovered the leather-bound grimoire hidden behind a loose brick in the boiler room during routine maintenance. Thinking it was just another student's forgotten prop for the drama club, he stored it in his supply closet until prom night, when curious students found it while looking for extra decorations. The ancient text's power overwhelmed Frank first as he tried to intervene, twisting his decades of institutional knowledge into a roadmap for hell's invasion through the school's very infrastructure.

The Corrupted Custodian manifests with a twisted mop that drips black ichor, leaving trails of corruption that warp reality around them. His key ring jangles with skeletal fingers that unlock any door, while his maintenance cart now carries vials of concentrated hellfire and cursed cleaning solutions that dissolve flesh. He can phase through walls using the school's blueprint knowledge and commands lesser demons through the intercom system, his voice distorted by static and ancient tongues. The scent of industrial cleaner mixed with brimstone follows his presence.

Hell's head custodian maintains order in the chaos, ensuring the demonic takeover proceeds according to the ancient texts' specifications. He coordinates the possession of strategic locations, from the gymnasium where the portal first opened to the administrative offices where survivor resistance organizes. His intimate knowledge of every crawlspace, ventilation shaft, and utility tunnel makes him the perfect overseer for hell's logistical needs, while his twisted dedication to 'cleaning up the mess' of survivors drives his relentless pursuit.
