Lusankya
this planet was supposedly the site of an Imperial prisoner reconditioning facility used by Ysanne Isard. It was later revealed, after the New Republic liberated Coruscant, that Lusankya was simply a prison facility built into the carcass of the Super-class Star Destroyer Lusankya, which was buried beneath Imperial City. The prisoner barracks, interrogation facilities, and office spaces were located within the Star Destroyer, while a mining operation was established in the crust of the planet. It was here that Isard interrogated and tortured her prisoners, all the while conditioning them to react to certain code phrases. When she was satisfied that the prisoners were ready to be released, she removed any memories of their captivity except for the fact that they were at Lusankya. Then, when the prisoners later heard the code phrase, they began mumbling about "Lusankya" before becoming living time bombs and causing great amounts of damage, usually to New Republic locations. If a prisoner could not be turned to her conditioning, they were consigned to the mines, breaking big rocks into smaller rocks for months and years on end. This was deisgned to break any non-cooperative subjects until they might be trainable in the future. The mines were constructed with a gravity-inversion field in place to disorient the miners. The entire complex was located near the Galactic Museum.
