Deny Bangaal's request

Recruit Commander Fastner had told you before you'd left on your graduation day that chaos magic was powerful stuff, little understood by humanity, and should be used with **** caution. This definitely did not seem like a case that called for chaos magic. You told her as much, then almost immediately regretted it, as she spun away from you with a flourish of her exotic silk.

"Lavender Vin, you are a squire, yes?"

She seemed calm and collected as she resumed her solo dance. She also seemed to be waiting for an answer to her rhetorical question. You nodded dumbly.

"You are one of the world's gentlemen who will know its greatest pleasures. Six wives, blessed in magic, talents, and beauty. You will not want for happiness. But all that you will obtain is what you have taken. It is what you have wished for. You understand?"

You continued to watch her hypnotic dance, feeling as though you were under some sort of spell, even now.

"To obtain happiness, you must wish. I want you to use Bangaal's magic as freely as you will. Bangaal's magic grows stronger from the wishes of a beloved human. Without your wishes, it will become like a rusted blade. Bangaal may be inclined to seek a new lover."

You told her that you weren't planning to keep her chained up without ever using her magic. It was just that, in this instance, it didn't seem... strictly... necessary? It was very hard to put up a fight against her while her psionic influence was still in your head.

The djinn's eyes curved into amused crescents. "You have a strong willpower. Bangaal likes that. But you must open your heart to Bangaal and her magic, squire. And you will... In time. I see it in the flames..."

Just then, the fires of the torches all around went out and the jingling of her rings stopped. When you blinked, she'd vanished entirely. Would she come back later, when it was time to set out on your quest? You could only pray.
