Kalakar Six

Kalakar Six was a volcanic moon located in Dromund Kalakar, part of the Outer Rim. The surface was covered in lova. During the Great Sith Civil War, The Sith Empire build a research facility on this moon, however, a incident happened which killed almost everyone in it. Survivor's included The Dark Hero, Scarlet, X1-Z6, and R1-R6. When Darth Namla, Naiko and their forces arrived to kill the remaining survivors, they destroyed the support beams holding the place together and the facility was destroyed.

Thousands of years later, Darth Vader came her to hunt down a group of Rebels who seemed to have obtained the Death Star Plans. There were no Rebels but instead a clone of Darth Maul.
