Nirvana

Nirvana is a hidden refuge accessible to Priests which their angels may deliver them to in times of trouble. It is a single chamber, appearing as a flat, grey expanse, utterly featureless save for a lone monolith of grey stone. Nirvana is both the name of the arrival point and the name of the plane itself.

An adventurer without Spirituality cannot journey to Nirvana alone and may only tread there lightly; the planar wards reject non-priest adventurers who enter the realms there, transporting them to outside the cave.
