Having recovered from their encounter with Dr. Myrin, the party went in search of the Hanged Man. Eren had explored one of the other buildings that made up the former magic academy that the Hospital was not using, and found a mirror inside. This, they decided, would be the best place to fight the Atu. Dodging dozens of leech-like creatures, the party ran for the mirror. Eli's pendant floated up to sit in the lock at the top of the mirror, as Dr. Sang's stone had for the one in his office. They stepped through the mirror, finding an older, dustier version of the library they had just left behind.
The Hanged Man very nearly killed the party, with several people dropping in and out of consciousness. The lonely Atu moved quickly across the library, tearing through each person's strength. Having defeated several of the minor suites, the party was unaccustomed to fighting anything this powerful. The Court of Eight defeated the Atu by the skin of their teeth, earning a "XII" mark on their right arms. Mollye and Samorn had to be carried, unconscious, from the mirror world back to the Hospital.
