Cathuria

A legendary paradise sailors speak of but none can verify, situated past every charted dream-country and, on the one occasion someone sailed far enough to test the rumor, apparently past the edge of the ocean itself.

Whereabouts: Somewhere beyond the basalt pillars of the West, according to sailors' report; no vessel that has sailed for it has ever been confirmed to arrive.

Access: By ship, past every other dream-land on record, over a stretch of ocean that the one detailed account describes ending in a waterfall pouring the world's seas into open nothingness.
