Around 4 ABY, the Director of Imperial Intelligence Ysanne Isard, using a Spaarti cloning cylinder from the late Emperor Palpatine's storage, grew a clone of herself on her Executor-class Star Dreadnought Lusankya, which was hidden beneath the surface of the galactic capital of Coruscant. Isard constantly updated the memories of the clone, who was kept in a state of suspended animation, to ensure she would believe herself to be the real Isard upon awakening. After the New Republic conquered Coruscant with the help of the elite starfighter unit Rogue Squadron, Isard retreated to the planet Thyferra, establishing a regime there.
