Between some rocks, and a hard place

MIss Adventure jumped when she heard the rocks fall behind her. Dust filled the small passage. She took a few steps back, coughing, into the chamber behind her. She was about to run to Gruffydd's aid when she heard a low moan, and sensed movement behind her in the chamber.
When she turned, she saw 4 shapes rise from the floor of the room. There was the clanking of armor, and the low moans again.
"Ahhh, not zombies....."
She was trapped.
