Have you ever wondered what goes on inside of a GM’s brain? Well, today we’ll find out! 

MEGA MASTER MINDGEON is an adventure that will take you through cerebral twists and turns you never thought you could explore! The GM’s mind is now a slave to itself, trapped in a loop of stagnant and repetitive thoughts. This prison is represented in the way it knows best: a DUNGEON (of course)! If once the forces of good and evil provided balanced ideas for creating adventures, NPCs, objects and fantastic places, today evil devils and demons populate and direct the entire neural complex like a factory. Little remains of the GM’s own consciousness and the forces of good embodied by celestial beings are survived only in small pockets of resistance in remote corners of the mind. 
What can the PCs do to save the GM from his own fucked-up brain?
