The room beyond is a mess. Evidently it was once a nice-looking place, but years of decay have worked their magic. The walls are hung with tattered tapestries, a chandelier lies broken on the floor. The stairs are cluttered with mess, but you force your way through. The rest of the floors are much the same; once, they would have been passable as the living quarters of a minor noble family, now they are ruined.

There are sketches for strange machines, though nothing for the Crow's wings- in fact, there is a suspicious absence.
