The Twilight Council is a structure on the Protoss Technology Tree, which requires a Cybernetics Core before it can be warped in. The Twilight Council enables research of the Charge, Blink and Resonating Glaives upgrades. It also unlocks the Templar Archives and Dark Shrine structures, which in turn unlock the High Templar and Dark Templar units, respectively. Additionally, the Twilight Council is a requirement for the second and third Protoss Ground Weapons, Ground Armor and Shields upgrades at the Forge.
