Poster Antechamber

Room 1 - This room has many posters similar to disney haunted mansion, cartoony scenes representing D&D style gore and traps. Double doors are locked on the opposite side of the room with and enter at your own risk sign above them.
As you enter the large doors leading into this room you see another set of doors on the far end.  The room is about 20 feet by 20 feet so not that large.  Around you leading up to the tall ceilings are huge posters that depict several different scenes.  A Mimic slowly crunches on a fighters head in a slow gif like animation on one.  The next is a paladin cowering before a doll that stands menacingly above him, her eyes pulse with a glowing animation.  One just has a jester dancing back and forth slowly.  The next one is a monk in a big iron pot being boiled alive by little imp creatures who dance around it.  The last is a Rogue being digested slowly by a cute Gelatinous cube that has a little smile face on it and the rogue inside bobs up and down. 
As you get closer to the far doors they open on their own...
