In an effort to isolate Yuuzhan Vong communication technology and use it to her advantage, Jaina Solo sought out Khal during the Yuuzhan Vong War. To achieve results, a captured pirate named Crimpler, who had a coral implant in his neck, was "experimented" on into a near-death state. After two days, Khal got the desired results, and gave them to Jaina to use.
