During the briefing, Magellan picked up a transmission on the hyper-waveform emitter, which he showed to Mengsk and the commander. Somehow protossPraetorMojo was able to contact him telepathically from a stasis cell. Mojo advised rescuing a number of protoss whom Schezar had imprisoned in the vicinity of the cerebrate. He also advised not killing the cerebrate, as this would cause the zerg to run rampant and overrun both forces.
Mengsk ignored the request, but Magellan chose to honor the protoss and rescue them. He later traveled to Aiur, seeking to rescue the protoss Praetor, Mojo, from the same Scavengers, in which he succeeded.
Magellan (along with Kazansky, Mojo and a number of other terrans and protoss) participated in an assault on Schezar's main base on Aiur along with its associated cerebrate. He quickly detected the presence of a strange breed of ultralisk, the torrasque. Mojo informed him it could reincarnate from death, but Magellan noted its genetic similarity to Schezar's pet cerebrate. He believed killing his cerebrate would prevent the Torrasque from reincarnating. Magellan was last seen attacking the Schezar's Scavengers base on Aiur, seeking to destroy its enslaved cerebrate and Torrasque. His forces were successful.
Reduces the hit points of biological units near the targeted unit (and the targeted unit itself if it is biological) by 250 over 30 seconds. Mechanical units are immune, but biological units passing near an irradiated mechanical unit will still be affected.
