In 2259, when Psi Corps held its annual convention, the Mix's president, Arthur Malten, and his assistant, Emily Crane, devised a plan to take over Psi Corps. Creating a fake Martian radical group called Free Phobos, they staged a bombing at the Royal Tharsis Lodge on Mars, where the convention was scheduled to take place, causing the venue to be changed to Babylon 5. They staged another bombing there, for which the station's resident telepath, Talia Winters, was framed. The bombing killed several high-ranking officers from the Psi Cops and badly wounded Alfred Bester. In the ensuing chaos, Malten attempted to have a bill pushed through that would cause Psi Corps to become part of the Mix.
However, Malten and Crane's plans were foiled by Michael Garibaldi and Harriman Gray, and both were killed - Crane was executed by a vengeful Bester, while Malten, in a grim irony, was killed by Martian radicals who took a dim view of his fake radical group.
