Qujaga is an oceanic planet in Tormented Space, covered entirely in water. The waters of the planet-wide ocean contained chemicals that had healing properties. It was, for many cycles, believed to be uninhabited until it was revealed that the surviving Eidelons dwelled there. They lived on a small island that was cloaked using a concealment canopy.
Unfortunately, not long after this became known, the Scarrans sent a force to the planet to eradicate the inhabitants. The survivors were evacuated from the planet, which was ultimately destroyed by the gravitational force of John Crichton's wormhole weapon.
Qujaga appeared in an episode of the fourth season of Farscape and in Farscape: The Peacekeeper Wars.
