Star Trek Expanded Universe

Rura Penthe was a prison colony of the Klingon Empire located on an asteroid in the Beta Quadrant of the Milky Way Galaxy. Surface conditions were harsh and frozen, the actual colony was subterranean, where prisoners mined dilithium. The gulag had existed since at least the early 22nd century, and was known throughout the galaxy as "The Aliens' Graveyard." (Star Trek VI: The Undiscovered Country, ENT: "Judgment")

Prisoners who grievously misbehaved were exiled to the surface, where nothing could survive for long. A magnetic shield surrounded the colony and served as a transport inhibitor, preventing escape. (Star Trek VI: The Undiscovered Country)

Mirror universe[]

In the mirror universe, Rura Penthe was a tropical resort planet. In 2410, Captain Oroku Seifer, Lieutenant commander Kugo, Lieutenant Kayl and Doctor Lox took an impromptu vacation and transported over to it from the USS Phoenix-X. (Star Trek: Phoenix-X: "Gender Swap", "Myths and Lore")
