Limbo

Limbo is an eternal, repeating dark void found between everything. It is the necessary interim that is passed through for a split second during teleportation.

It can be reached permanently by a bungling of the teleportation spell.

Granny Limbo's Cottage
The only permanent resident of Limbo is a woman called Granny Limbo.
