Vanqor had two red moons that orbited in tandem. It was a planet full of deserts, canyons, and highlands. It was primarily populated by Humans as well as wild beasts known as gundarks. A few years prior to the Clone Wars, Vanqor's inhabitants began a conquest that led to them controlling the entire Uziel system, except for the planet Typha-Dor.
Despite the lack of resources, it was able to create a massive amount of power for itself through cunning use of the resources it had and skillful conquest of those with resources, in contrast to planets like Typha-Dor and others that had large amounts of resources but no drive to succeed.
Vanqor was defeated by strategic maneuvering of the Typha-Dor fleet that allowed it to surrounded the much larger Vanqor fleet, partially with its own fleet and partially with Typha-Dor's two moons. The Vanqor capitulated without a fight rather than face the destruction of most of their military. A ceasefire was worked out with mediation from the two Jedi.
Early in the Clone Wars, Kenobi and Skywalker accidentally returned to the planet while pursuing the Separatist leader, CountDooku. They crash-landed on a desolate plain, and were attacked by a female gundark while tracking Dooku through a cave. Though nearly suffocating from a poisonous gas, the duo were saved by Ahsoka Tano and a detachment of clone troopers. Dooku slipped away from them by hitching a ride with a Weequaypirate gang who had landed to scavenge his crashed solar sailer.
Later, contact with the Venator-class Star DestroyerEndurance under the command of AdmiralShoan Kilian was lost as the vessel violently entered into the atmosphere of Vanqor following the sabotage of the engines by Boba Fett after his failed attempt on High Jedi GeneralMace Windu's life to get vengeance for Windu's killing of Boba's "father", Jango Fett at the Battle of Geonosis. While the crew evacuated the ship, Kilian remained onboard in the belief that an admiral must go down with his ship.
Jedi KnightAnakin Skywalker and Jedi MasterMace Windu descended to the planet in Jedi starfighters to look for survivors. However, the surviving crew had been slaughtered and the officers, including AdmiralKilian, taken prisoner by Boba Fett and his company of bounty hunters. Boba rigged his father's helmet on the bridge of the downed cruiser with a bomb inside it, and Skywalker and Windu were trapped under debris by the resulting explosion. Thanks to the efforts of Skywalker's astromech droid, R2-D2, the two were rescued by Ahsoka Tano and Plo Koon, summoned from the Jedi Temple. Boba and his retinue, however, got away with the hostages aboard Slave I.
