It is situated in Blackwind Valley in southeastern Terokkar Forest, only accessible to players who have a flying mount or Druids who have learned Flight Form. It is made up of four Veils: Veil Ala'rak, Veil Harr'ik, Lower Veil Shil'ak, and Upper Veil Shil'ak. At its center is Terokk's Rest, the site where the arakkoa lord Terokk can be summoned back into the world.
