Twilight is a reference to a combination between the Khala and the Void. Few characters have wielded it, due to the history of animosity between the Khalai and the Dark Templar. Wielding the power can be extremely dangerous. Tassadar, one of the few characters to do so, is sometimes known as the "Twilight Messiah". After the Great War, the union of Khalai and Nerazim on Shakuras became known as the Twilight Council.
