Frieren led Albedo back to Strax's main mansion without explaining anything else along the way.
The two crossed the entrance hall, passed through the library, and continued into a corridor used mostly by the servants. Albedo knew that part of the mansion, but she had never noticed anything suggesting the existence of an underground passage. Frieren stopped in front of a wall covered by an old tapestry, pulled the fabric aside, and pressed three different points between the stones.
Runes appeared on the wall.
Albedo watched the formation recognize Frieren's mana, confirm a second signature hidden inside the crystal she carried, and finally analyze her own demonic presence.
"How long has this existed?" she asked.
"Since shortly after the mansion was rebuilt."
"And no one noticed?"
"Monica knows."
"Naturally."
