The Khala

The Khala, or "The Path of Ascension", was the religious law of the Protoss in StarCraft, established after the era called the Aeon of Strife that followed the departure of the Xel'Naga. Khalai society was divided into castes, and the Preservers maintained the telepathic network that unified the Protoss. Before the Brood War, Protoss society was split between the Khalai and groups such as the exiled Nerazim and the heretic Tal'Darim. In Legacy of the Void Amon seizes the Khala and controls the Protoss through their nerve cords, so Artanis and other Protoss have their nerve cords cut to break free of it.
