Kalakar Six was a volcanic moon of Dromund Kalakar in the Outer Rim. It was covered in lava flows, its crust riddled with magma tunnels. Kalakar Six was a Dark Side nexus which was once occupied by the Sith Empire. It was located in the same system as Dromund Kaas, the location of the Dark Force temple of the Prophets of the Dark Side. Rumors held that around 100 BBY, the moon's dark side nature attracted Baron Yorn and his followers from Coruscant, who set up a fortress with the intent to conduct experiments there. However, a supply ship later noted that everyone there had vanished, except for Yorn, who had gone mad, tearing out his own eyes and tongue. Derriphan Academy
