Gate of Souls
Another class of ethereal plane that some have speculated about, and other claim to have seen, are the Heaven’s of various deities that no longer manifest on the Prime. None have ever managed to establish a reliable portal to them, and the descriptions given by those few plane walkers that claim to have found such a realm are considered inconclusive. Were these really realms in their own right or simply stable patches of Prime ruled more directly by a deity? Perhaps even some deep elemental zone or demonic plane.
