Warning: Spoilers ahead. Unless you've read up to Volume 17: Alicization Awakening - Chapter 20: Each of Their Battles, continue at your own risk.

On a related note, and sorry if this is going slightly off-topic here, but according to defan's translation the four Super Accounts were designed for direct operations ("miracles") on Underworld and its inhabitants: Asuna (Stacia) can change the geography; Sinon (Solus) can destroy mobile units; Leafa (Terraria) can recover durablities; and Subtilizer (Vector) can control Underworld Residents' Artificial Fluctlights, i.e. edit the AI subjects' memories and relocate them.
