Inside the stone lodge beside the tarns are locker rooms that open directly into the outdoors. There are separate rooms for boys and girls, as well as small private rooms for those who prefer privacy or exist outside of the traditional binary. Here, students can change into swimwear in summer, or skating gear in winter. The rooms are simple but well-kept, with long wooden benches, rows of enchanted lockers that dry damp clothes in minutes, and hooks charmed never to lose a scarf or glove hung on them. Oddly, in both locker rooms, there is always the same ugly, ratty striped towel draped across one bench. No matter how many times it is thrown out, burned, or banished, it inevitably returns within a day, damp to the touch and faintly smelling of lakewater.
