Influenced Region—Armoury!
In the centre of the ivory sand was a vortex, built out of a dense sand cluster. Swirling voids appeared in the intersecting paths of multiple streams of ivory sand merging into the cluster. These voids were gates leading into the interior of the cluster, where the Spirit Weapons were stored.
Every single Spirit Weapon was contained by a small vortex of ivory sand, maintained by the formless power of psychokinesis ever-present. The ivory sand was merely the medium in use, while the true Influenced Region was the mass of psychokinesis that had coagulated within the cluster.
Originally, shining in the centre was the Major Treasure of Weapon, constantly using its influence to build the Armoury. Now, it had completed its purpose as Armoury was finished. The moment this was done, it ought to have shone its pillar of light, sparking the start of the Third Major Disaster.
