Templar archives

The Templar Archives are dark, mysterious buildings that serve as training centers for the legions of both the High Templar and the Dark Templar. These honoured warriors, charged with wielding the awesome psionic powers of their race, use the Archives to directly commune with their ancient ancestors and thereby gain knowledge inaccessible to ordinary warriors. Due to the fact that both the High and Dark Templar's Templar Archives look identical suggest that the exterior design of the building is very old, dating back to before the Dark Templar were expelled from Aiur. After Tassadar reunited the High and Dark Templar they became able to share Templar Archives.
