“The emperor put as many magi as he dared trust to work on both magical problems. He believed that Layinisa might hold his empire after his death, but if she were infertile, that would only delay the collapse, and he didn’t want to be yet another emperor whose empire died with him. In the end, it was Layinisa herself who discovered a way around the rings’ bond.”

“She did?” Vi asked.

“Don’t get excited. Now we’re here, say nothing until we reach the library.”

They walked silently through the dark halls of the Chantry. Vi wondered for a moment that the building was beginning to feel like home. The dim magical torches that illumined the walls and followed them seemed normal now, the austere marble arches comforting in their strength rather than menacing. In a few minutes, they were deep in the Chantry’s storerooms, far below the waterline, a place Vi had never been allowed to go. It was neither dark nor dirty, but it did have an air of abandonment. Numbered oak boxes lined the room to the ceiling. The one small desk had an oak box already upon it.

Instead of opening the box, however, Sister Ariel closed it and put it back on a numbered shelf and grabbed a different box two rows down. Vi understood that she had left out the wrong box in case some spy checked what she was studying. At first Vi wondered why the boxes were oaken, but then she looked again and saw the spell sunk into the wood. Each oak box had one spell to strengthen the box and make it watertight, one to make it fire resistant, and one to suck air from the box as it closed to preserve whatever was kept inside.

“Magically reactive materials are kept in special rooms on the next floor; these archives are for mundane records only. Because of how they’re preserved, they only have to be copied by industrious tyros such as yourself every few hundred years—if they’re not frequently opened,” Sister Ariel said. The box opened with a hiss, and she gently lifted out sheets of bound parchment that to Vi’s eyes looked scarcely ten years old.
