Hall of Infinite Doors

You use the green key to open up the door. As you enter the next room you see that the wall is lined with coffins and in the center of the room there is a massive furnace. A strange bald man with a hunch back is lifting up one of the coffins and feeding it into the furnace. It seems that he is cremating the coffins and their contents. The strange man turns around as soon as he finishes feeding the coffin in and asks with an angry tone, "What the hell do you want?"
