What was that?

As you charge in, you hear a snap behind you and everything goes dark. You have fallen for the oldest trick in the book. As you look back you see teeth, in front the red-black of a throat.

Many Knights have fallen into that trap and many will after. This princess was never saved and the dragon ate her too in the end.
