The Square of Hierarchy was a location on Coruscant after its vongforming into Yuuzhan'tar, on the former Calocour Heights. During the Battle of Yuuzhan'tar, Nom Anor resumed his guise of Yu'shaa and defected over to the side of the Shamed Ones at the Square. The Garrison of Warriors from Shimrra's Citadel tried to herd them to the Place of Bones from the Square, but Jedi Knights and troops from the Galactic Alliance came to the aid of the heretics.
