Rattatak

Rattatak was a blood-soaked wasteland located on the far fringes of the galaxy. So mired in pointless warfare, bloodsport, and other horrible events was the planet, that it was literally covered in a blood-sand slurry. This caused the world to glow red when seen from space.

History
On this planet, Count Dooku first encountered the Sith-wannabe Asajj Ventress, who "proved" herself by first beating the snot out of various gladiators, then satisfying the old fart. Thereafter, she became one of his bitches Sith minions, tasked with stalking hunting down and killing Anakin Skywalker and Obi-Wan Kenobi.

After the Clone Wars, the planet was held by the Galactic Empire, which had stationed only a token force of stormtroopers there. Why? Because Rattatak was so piss-poor, the Rebels would never want to waste men and materiél to "liberate" it. At the time of the Battle of Endor, the occupying force consisted of the 140-trooper strong Pavan Platoon. After realizing that Emperor Palpatine had bought the farm, the entire unit vanished, leaving the planet to fester and rot.
