- "Rattatak is a world of warriors and soldiers. For eons, we have battled one another for the right to rule. We knew nothing of the outside galaxy or your Republic, but still found new and inventive ways to kill one another."
- ―Osika Kirske
Rattatak was a dry, arid, mountainous planet covered in red rock, judging by its appearance from orbit. Most settlements appeared to be hewn into the rock itself. Rattatak's climate was too harsh to sustain widespread agriculture.
Rattatak was one of the unexplored planets in the galaxy. Isolated, the Rattataki fought each other as well as at least one other sentient species in never ending battles. Their way of fighting evolved over the centuries, ranging from melee weapons to blasters.
Soon, a "warlock" fell from the sky, claiming to be an emissary of the Galactic Republic. On sight, they attempted to kill him, but he escaped and found Asajj. Finding that she was strong in the Force, he began training her as his Padawan. Together they united armies and brought peace to the planet. Unfortunately, the warlords feared them and united together to kill the pair; they only killed the master. In her rage, Asajj captured and/or killed every warlord responsible for her master's death and established a totalitarian regime over the planet.
Most of the planet was subjugated by the Stunger state.
It was here that Count Dooku first discovered and recruited Asajj as he watched her emerge victorious at the gladiatorial death matches of The Cauldron. He introduced her to Darth Sidious who gave the dark side warrior her first assignment, which was to kill Anakin Skywalker, only to test the boy on whether he would be the perfect Sith apprentice. Later in the Clone Wars, Obi-Wan Kenobi was transported to Rattatak by Asajj after her victory on Jabiim.
The planetary judicial system is centered around the gladiator games; those convicted, or even merely believed, to be guilty were summarily thrown into the gladiator pits for the remainder of their lives, short as they might be. The Rattataki are believed to have descended from an ancient Old Republic expedition, while the rest of the population are from hundreds of Unknown Regions worlds. Mercenaries often come to this world, but are stranded by the planet's failed infrastructure. Most animal species have been hunted into extinction, but a few alpha predators still roam the wastelands.
Behind the scenes
Rattatak is misidentified as "Rattaka" in The Life and Legend of Obi-Wan Kenobi.
On the profile page for Rattatak in the Essential Atlas, it is erroneously said to be in the Unknown Regions.
