Final Quest

"Torai, can you breathe fire on the sacks to burn them?" you ask him. "It might have more effect than my sword."
Torai stares at you, then shrugs, and positions himself so that he can aim at the sack. Then, he takes a deep breath, and lets out a blast of fire at the sack, burning it to ash.
You have enough time to wonder whether you've made a mistake before the figure of a woman carefully uncurls itself from the remains of the sack. From her lithe, slender form, you guess that she's a nymph. But then, you let out a cry of horror.
The nymph's hair is jet black, something that nymphs don't usually have. Also, her dark eyes shimmer black as night with an evil twinkle in them.
The corrupted nymph's lips part. "Free my sisters," she orders you with a sibilant hiss.
You scream. That voice was never meant for human ears! Behind you, you can hear Alasse cry out in pain, but you can't spare her any attention.
You have two choices.
