Limbo

Limbo is a place where volunteers are sent during the Teleportation Trick. It was used as a dimension to transport a volunteer during the act, when ready the volunteer would be returned to another Teleportation Box.

Location:
It is an unknown dimension between the Teleportation Boxes used in the Teleportation Trick. The only way to enter Limbo is to either press the Skull Button on the Control Panel inside the boxes or (if caught) Orpheo will perform the Teleportation Trick which will send Terry and Alex there. Once in Limbo there's no escape (except when pressing the Skull Button in the Defective Teleportation Box which will return Terry after 1 to 2 minutes).

Effects of the Curse:
Since Orpheo's Curse was cast, the Teleportation Trick that was performed on the Theatre Stage would go wrong. Meaning that any volunteers would be sent to Limbo and lost forever.

The first person to be lost and sent to Limbo was Elizabeth (Orpheo's Assistant and youngest daughter) because Mary (Orpheo's Eldest) was hateful towards her sister. After that, any volunteers of the Teleportation Trick would be sent to Limbo forever while the curse is in place.
