The Underworld Entrance is the entrance into the Underworld of the Realm of the Dead. The entrance is a huge tendon-covered skull. The hideous skull-shaped formation's mouth is the doorway the Underworld below. The door appears to be made out of tendon-like filaments whih retract to 'swallow' the souls which enter. It is the portal through which all souls must pass to enter the Underworld. It is guarded closely to prevent any mortal man from getting in... or any soul from getting out. Living skeletons are gathered around the entrance.
