Taking an elevator of sorts to the third floor, the party found themselves in a library. Preserved from any frost damage were many shelves of books, full of knowledge on countless topics. After disabling a flame trap at the desk, the books were looked over before deciding to save them for later and move on.
Carefully opening the next door, fully expecting ambush by elementals, golems or damn-near anything else, the party found itself in the master suite. Once expensively decorated, carpets and tapestries inside were brittle and stiff, long-since frozen. A large bed dominated the room, a frozen pillow on top and some frozen socks underneath.
A 5-foot high mirror stood next to the wall, four stiff corpses laying on their backs facing the mirror. The mirror’s surface rippled here and there, like the surface of a pond. After some initial investigation and the defiling of a corpse, the party assumed the mirror must show the way out of the room. They tried pointing it at the wall, then looking into the mirror to see the ‘true’ wall…but found themselves staring at the reflection of a halfling inside a black void.
