The Garden of Aiur was formed at the end of the Aeon of Strife, established as a center for peace, tranquility and reflection on the ways of the Khala. After Aiur fell to the zerg however, it became a focal point for pitched conflicts between the zerg, mercenary terrans and the few remaining protoss forces who remained on their homeworld. Ironically, this could be said to have benefited the garden, the blood of the fallen 'feeding' it.
The garden serves as a multiplayer map for StarCraft, supporting up to eight players. It is an adaptation of the map Garden of War from Warcraft II.
