Lusankya, a private prison controlled by Ysanne Isard, was situated inside the Executor-class Star Dreadnought also named Lusankya. This massive vessel was concealed beneath the urban environment of Coruscant. Within this dreaded clandestine prison, Isard employed brainwashing techniques on her prisoners, transforming them into secret agents who would be activated at a later time. To disorient those attempting to flee, the Star Dreadnought was constructed with an inverted orientation, using artificial gravity to make floors appear as ceilings. The interior of the prison was designed to resemble a mine, with stone cladding, leading prisoners to believe that escape attempts would lead them to the surface, when in reality they would only venture further into the Star Dreadnought, which was under the control of Isard's staff.
