Aiur is a huge world located on the fringes of the Milky Way Galaxy. It was engineered by the Xel'naga and left to itself for a long period of time. When the Xel'naga returned, they discovered the Protoss on the world. They guided protoss to evolution, albeit too fast. As a result, they were forced to flee, and the Protoss fell into a racial madness-fueled conflict called the Aeon of Strife.
Aiur was devastated in the Aeon of Strife but after the period ended, it began to steadily recover.
The Fall Edit
Aiur was attacked by the Zerg Swarm in an attempt to consume and assimilate the entire Protoss species. Though the Overmind was destroyed by the mighty high templar Tassadar, who sacrificed his life in a kamikaze strike using dark templar energy, it was at best a pyrrhic victory: the Swarms had infested most of the planet, killing 70% of the Protoss of Aiur and ruining much of the landscape. The Zerg have scoured almost all non-Zerg life from several continents. The jungles are now littered with ash, broken war machines, and corpses.
The planet was abandoned shortly thereafter through a Warp Gate which connected to the Dark Templar homeworld of Shakuras. Hundreds of thousands of Protoss died during the evacuation. Some protoss were stranded on Aiur, and others volunteered to remain behind in order to defend the Aiur end of the Warp Gate.
The Warp Gate was destroyed when the United Earth Directorate invaded Aiur in their quest to arrest Terran Dominion emperor Arcturus Mengsk. The stranded protoss belonged to several groups; one led by Fenix and Raynor, as well as the Shel'na Kryhas and the Tal'darim. The latter, serving a mysterious Benefactor, learned strange powers.
Four years after the Brood War, Aiur is still occupied by the Zerg. While they have stopped killing each other, they still wander Aiur like "discarded tools" and have stopped spawning minions. The Shel'na Kryhas and Tal'darim clung to life on the ruined world, fighting and avoiding conflict with the Zerg. The arrival of a preserver, contained within the brain of terran archaeologist Jake Ramsey, brought great changes to both groups of Protoss. The former attempted to flee through the disabled Warp Gate, while the latter splintered as they learned the truth behind their mysterious Benefactor. Members of both groups banded together to attack the Benefactor, most giving up their lives using a powerful psionic technique to hold the Benefactor off.
