otherworld

Now the glass mountain is a well-recognised form of the Otherworld prison.

The most persistent British belief, however, was that after death the soul passed to an Otherworld.

Besides a belief in a land of the dead, the Celts had an Otherworld to which favoured mortals might penetrate.

On the other hand, the Otherworld becomes the Underworld, because of the subterranean burial of the dead.

The Otherworld, shrouded by mist, was upon the same plane as the terrestrial, or sometimes co-extensive with it.
