Perhaps to your surprise, the statues do nothing as you pass them.
You open the next door to reveal a large library filled with wall to wall bookshelves and books. A red-ish carpet lines the floor and it's eerily quiet here. A woman is carrying a stack of books and bringing them to various places as if sorting them. Then she picks up books from another shelf and shuffles them around. She completely ignores the 4 of you, even walking in between without acknowledging your existence.
As soon as everyone is inside the library, a loud crack as if from nearby thunder shakes the room. For a split second the room goes completely dark, as if the exact opposite of a lightning strike. Only those inside the library or hallway notice it. Books rain down from above as they have been shaken loose. In the hallway, the legs of one of the statues breaks and it topples forward, partially blocking the way back.
OOC:
Everyone must pass a DR8 Agility or Toughness check or take 1D2 damage from falling books and bookends.
As soon as she gets up again, the woman starts collecting the books on the floor and replacing them on shelves.
