Sebacean

Sebaceans are an engineered race of humanoids also called Peacekeepers.

Their history begins roughly twenty seven thousand years ago, when a race called the Eidelons were trying to bring peace and order to the universe. However they were often met with aggression and violence but being peaceful they were unable to defend themselves. So they travelled to the edge of the galaxy and discovered a primitive race (Terrans) and found them to be extremely adaptable, so having made either choice they made alterations to the DNA of those they took back with them and created the Sebaceans.

From their actions along side the Eidelons they earned the name Peacekeepers. Several thousand years ago the Eidelons disappeared and soon, without the guidance of the Eidelons the Sebaceans took to keeping the peace the only way they knew how - down the muzzle of a weapon.

Physiology
Though externally identical to humans they do differ from them in various ways: for instance above a certain temperature (45 or 55°C) they have an extreme intolerance for heat which sends them into a permanently vegetative state. Another feature is the ability to "pause" pregnancy for a long period of time, potentially over a year. They are also subjected to a painless birth.

They are capable of interbreeding with other races such as Luxan's and Scarrens but the practice is normaly frowned upon due to a doctrine of racial purity. Few Hybrids ever make it to adulthood due to death by Peacekeeper hands or conflicting accepects of their duel parentage.

The Peacekeepers
Through the decades they developed into a mercenary protection force in which planets or even star systems would bid for their military services. However once under the protection of the Peacekeepers they are often duped into a more permanant arrangement, sometimes ending in the world(s) being totally handed over to the Peacekeepers. This essentially makes the Peacekeepers similar in a way to mankind's many mafias.

Although originally comprised of Sebaceans the Peacekeeper Corps has expanded to include various other species (though whether or not these species volunteer or are forcibly incorporated is not clear).
