Protoss commanders can research additional upgrades for their units at the twilight council when playing in the Co-op Missions mode of Legacy of the Void.Alarak builds a "death council" instead of a twilight council, a variant of the building with identical stats and position in the tech tree, but with a Tal'darim skin instead of the standard one.
The following section contains information from a previous version of StarCraft II which is no longer valid.
The twilight council was initially built as a placeholder tech building to visually signify the tech path chosen by a protoss player. The three diamonds had glyphs which would appear depicting the robotic, high templar or stargate high-end technology. The role overlapped the buildings which already signified those technology unlocks (the stargate, robotics facility and templar archives) so the function was changed so the building unlocks unit abilities instead. As one of the later protoss structures developed in the game, the twilight council features more white surface detail to break up the prodominant gold/teamcolor treatment that had been used on the other protoss structures.
