Battle of the First Overmind (Shadow Hunters)

The Final Battle of Aiur was a decisive battle which ended with the death of the Zerg Overmind and the sacrifice of the Protoss hero, Tassadar.

Assault on the Overmind
After be released from the Conclave prison, Tassadar put his attention to defeating the zerg. Zeratul revealed what he had learned when he killed the cerebrate Zasz on Char. The zerg were creations of the xel'naga and the Overmind was determined to complete the grand experiment of creating the perfect life form. Stopping the Overmind was imperative not just to ensure the survival of the protoss, but of countless other life forms as well.

The comrades planned to reduce the zerg defending the Overmind allowing the Dark Templar to kill two of the cerebrates. They hoped those deaths would distract the Overmind long enough to allow them to strike the Overmind directly. As a twist of fate Gorn, the cerebrate Fenix had unsuccessfully attacked earlier, was one of the targets.

Tassadar's forces were joined by sympathetic judicators who brought with them Arbiters. The attack was successful. Slain by the Dark Templar the cerebrates could not be reincarnated, defeating their respective broods once for all.
