I think he's looking for "The plane of Ooze…" Which is nothing more than a pocket dimension on the Ethereal Plane or Border Ethereal, i.e. The plane of Entropy is the start and ending of existence for the "Prime Worlds".

The Rift, can be "The Astral Plane", "The Ethereal" or the Space between two "Crystal Sphere's", which exists in "The Well of the Worlds". In which case:
Just think of this guy as a Mid-evil spaced - out - Hippy. :lol:
