Anything
You were just sitting at your desk, waiting for class to start. The teacher is late; the students around you were chatting with eachother. You absentmindedly feel the bottom of you desk... which is a bad idea, with how much gum people put under there. But... you also feel an odd wooden extrusion? You pull it and feel it detach from the plastic table. You take a look at it: It's somekind of talisman. The emblem has a distinct native American feel to it, but you can't place it any more specific....
