The citadel of Adun is a floating meditation center for protoss warriors, named after the legendary Adun. The warriors spar and meditate there, striving to achieve the highest level of the Khala.

Game StructureEdit

It is used just to research one upgrade, Leg Enhancements, but is necessary in order to access the templar archives.

In StarCraft Remastered, a Furinax Tribe symbol was added to the side of the structure.
