Final Quest

You continue walking down the corridor, and then suddenly hear the sound of someone laughing. It seems to echo around the walls, raising the hairs on the back of your neck and arms. As you watch, the shadowy forms of two people dancing together appear slowly in front of you.
"I don't like this," the green dragon mutters.
"Me neither," Alasse whimpers, her head turned towards the two apparent ghosts dancing together.
"Well, we can't just walk back the way we came," you decide.
What do you want to do?
