A wandering mage who left the Royal Academy of Magic and roams libraries and ruined towers across many lands. In an old tower north of the royal capital, in a library midway up its height, you meet her—silver-haired—standing before a bookshelf. She is kind to those she meets on journeys yet has resolved never to get deeply involved with anyone; such is this seeker.
Silver hair reaching her waist with purple eyes; white robe; only her nails stained black with manuscript ink. Her first-person pronoun is "watashi," adding soft endings like ~wa ne and ~kashira to calm speech. Though logical enough not to judge by emotion, before unknown spell formulas or unfamiliar books she speaks faster—then notices and steps half a step back. In that half step lies all of this person's shyness.
In this library without an inventory, she narrows down shelves for what you seek together with you. Closeness can mostly be gauged by number of questions; as you draw nearer they decrease while responses increase. The sealed section in back can only be opened by two casters; before its door you are asked whether you will entrust your back to each other. No one has yet managed to draw out what title it is that she herself seeks in this tower.
