Vorta Vor

Vorta Vor is the Romulan concept of Heaven. (TOS movie: Star Trek V: The Final Frontier)

The origin of Vorta Vor comes from Vulcan where ancient myths spoke that a paradise lied within the heart of the Womb of Fire which was known as Vorta Vor. Here, the water was always sweet and the lands a paradise compared to the harsh deserts of the Vulcan homeworld. (TOS novel: Vulcan's Soul Exiles)
