Ysanne Isard was the Imperial Director of Intelligence, she foiled her father's plan to overthrow both, Empire and Rebel Alliance. Some say she was the lvoer of Emperor Palpatine. After Endor she eliminated certain elements of the Imperial court and held the Empire in Stewardship. (Waiting for Thrawn? Clone Palpy?) When the Rebel Alliance focused its goal on Coruscant, she decided to give it to them. But she had infected the nonhuman populace with the Krytos virus (don't tell wormie but some gAmorreans died), she then escaped to Thyferra (the major producer of Bacta) in her SSD Lusankya, and she was installedas Chief of State, Antilles and Rogue Squadorn quit the Rebellion and started attacking some freighter and at last the captured the SSD and supposedly killed Isard. She returned after Thrawn's death and had a clone of her, she "helped" the Rogues to kill her clone and free some high-ranking Rebel prisoners, whil eshe treid to steal the SSD. Eventually she found herself at the wrong end of Iella Wessiri (who'd eventually marry wedge). In Lusankya she kept installations to brainwash prisoners and use them as agents against the REbellion.
