Okay, you're going to let it draw blood, then.
...
Nothing happens. It's sheathed, and you put it down in your room.
Anyway, you decide to observe and make contact with the student. In the course of a short hour, you make out a woman dressed in nondescript robes calling on him, and leaving with a prepared document. Immediately after she leaves, several other students head in, and they have a wine cask with them. A few moments later, you can hear revelry starting inside, and you sneak in just as one of the partiers leaves for whatever reason.
You then find your way upstairs, and the party is heading out, and you recognize the original student leaving, slightly more red-nosed. You catch the door open behind them, and they all tumble down the stairs oblivious to your presence.
Inside you find that he has three rooms. A sitting room with a small table, a bookshelf with about a dozen titles, and three simple wooden chairs. A bedroom, with a plain sleeping mat and a small closet, and an office, more decorated with some wall hangings, a couple unlit lamps, and a more solid looking desk with a padded chair behind, and another plain chair for visitors. In the corner is a hatstand, with a formal magistrate's cap on it, sans ribbon, befitting a student.
On the desk is ink and brush, a wooden stand, an unlit candle, and the metal seal you are looking to recover.
