Hierarchy of Hatred
this was Booster Terrik's name for the methodologies used by Ysanne Isard. He developed the hierarchy with the help of Mirax Terrik and Iella Wessiri, after it was revealed that Isard was working for Prince-Admiral Krennel. However, when Whistler and Gate returned from the loss of Rogue Squadron over Distna, they realized that they were working with two Isards: the real thing, which had agreed to help the New Republic bring down Krennel, and the clone, which was working for Krennel. The hierarchy involved setting up the parameters around which Isard would retaliate for certain actions. It was based on historical data, and allowed them anticipate Isard's reactions to given situations.
