Sebaceans

Sebaceans are a fictional space-faring humanoid species featured in the US/Australian science fiction television series Farscape. They are one of the dominant life forms presented on the show and are represented by characters such as Officer Aeryn Sun, Captain Bialar Crais and Commandant Mele-On Grayza.

Outwardly, Sebaceans appear no different from a baseline Earth human and in fact, are descended from ancient Earthlings. Another race of aliens, the Eidolons, took members of Earth's humans from their home world and over the course of centuries, they evolved into the present day Sebaceans. Physiologically however, there are radical differences between Sebaceans and humans. Though they have stronger physical attributes and more acute senses, Sebaceans are extremely susceptible to heat. Intense amounts of heat will cause a Sebacean to slip into a delirium, which is ultimately fatal.

More than any other race in the universe, Sebaceans are genetically compatible with other races for the purposes of producing offspring. Officer Aeryn Sun had a child with Earthling John Crichton. The pregnancy no small degree of complication however, as Aeryn's baby had to be physically midwifed through a surrogate vessel - the Hynerian Rygel XVI. The Peacekeeper commander Scorpius is a hybrid of two seemingly incompatible races - Sebacean and Scarran. Because of their differing biology, Scorpius is forced to inject a heating/coolant cylinder into his head at regular intervals or else he will die.

Sebaceans comprise the majority of a totalitarian regime known as the Peacekeepers. The Peackeepers are a territorial military dictatorship for hire who are at odds with several rival species, most notably the Scarrans. The Peacekeeper militia is one of the strongest in the galaxy, made up of massive command carriers and squadrons of Peacekeeper Prowler ships. Raised from birth to lead a military lifestyle, a Sebaceans first and last duty is to the Peacekeepers.
