There's an unusually small number of people moving about in the hallways.
She gets to wait about fifteen minutes before Lingormr emerges from his office. "The study room is a bit of a walk from here," he says, then leads her through a winding, maze-like mess of narrow corridors with thin slits in the walls that Kaede can't see through. At the end is a heavy door flanked by two guards. Lingormr steps up to it, and something happens - the quality of the air changes slightly, and then the door swings open as if of its own accord.
Beyond is a decent-sized room. In the middle is what must be the jewel - a softly glowing ball the size of Kaede's thumbnail, on a string of painted wooden beads. The jewel is held in a light clasp. Kaede can feel it from here; it's like the sensation of Tetsuma flaring their chakra, but more. Like a fire held in a too small a container.
There are workstations about the room, and three of the mages are busy at work.
