Hoops

"With the Seed and Stone that you brought me, I will make two earrings. However, I'm missing an essential part: hoops." "I once lent some hoops to a student named Tyrnal, but she never returned them, and now she denies ever borrowing them in the first place." "Go into the building that we are standing on and collect a stack of heads from the students there. Then take these to Tyrnal to intimidate her into telling you where the hoops are." "Tyrnal can be found in the building you see to the south."
