QI'tu'

Qui'Tu was a Klingon term for paradise and the afterlife.

Sybok believed a planet in the Great Barrier, known to the Vulcans as Sha Ka Ree, Humans as Eden and Romulans as Vorta Vor, was the location of Qui'Tu. 

By 2374, Quark had sold several maps allegedly showing the location of Qui'Tu.
