Different from other known dungeons, where spawning monsters can fight for the throne of Dungeon Master, the Crystal Mirror Dungeon could choose for itself and had a unique but simple way of selecting one.
Among all the Envy of the individuals who entered the Dungeon, it would choose and create a Visage of the strongest Envy with the sole purpose of protecting the Core and eliminating anyone who tried to approach it without proper authorization.
The fact that the Dungeon Master had changed from the gold-rank warrior adventurer of a few hundred years ago to an unknown girl meant that the latter was stronger than the former.
Whose Envy the Visage girl was supposed to represent wasn't important right now. What mattered was that the Crystal Mirror Dungeon recognized the girl as stronger than Brandon's Envy—the Soldiers' Commander—or Sylvie's Envy, which was Ellric's mother.
