Un-gag the Succubus and get some answers first

"Ok... I don't like being out in the open but I don't like the idea of unleashing a succubus more." You reach around the unresisting demons head and fumble with the straps holding the gag in place. You do your best to avoid her saliva as you pull the ring free and the succubus closes her mouth, visibly pained by stiffness.

"...Thank you dearie. I've been like this for weeks." You gawk and Janine gives her aunt an alarmed look, "Not her, they've been rotating her out with the others every few hours. In fact, her handlers are due back any moment so if you could just-"

"First: talk. What do you know about what's happening here?"

She gives you a strained but almost motherly smile, "But you figured it all out so well on your own dear, what could I possibly add?"

"Sabine? What's going on!?"

"Hush Janine, it's complicated. Give me something demon, you're the only one who knows the whole story and can tell it."

The succubus' smile shifted to wicked in a heartbeat, "Ah yes, your deity isn't so helpful for information now is she?" The boiling rage you felt was not entirely your own and you feel rather than see the knife light up with divine power in your hand, "Alright, fine. She can dish it out but she can't take it. I'll explain who I am and then the rest somewhere else: My name is Empusa, I've lived in these caverns since the last demon march, feeding off the repressed desires of the sisters above-"

That alone was quite a shock but she kept going, "-until I could no longer stand the hunger and sought out a man in the forests above. I bore his child, quite by accident, and raised her... as best I could."

The wheels were turning in your head and the name slips out even as the thought crosses your mind, "Selena."

Empusa nods, "As you can see, she grew up to be a handful. Now please get me out of these ropes? I wish your Burning Rose no ill will, I simply do not wish to return to hell."

You feel a grudging feeling of confirmation from The Rose, so you knew she was telling the truth... but she was still a succubus. Visions of Glenda come to your mind, unbidden and unwanted. A noise, faint but growing louder, in the passages in the walls. You needed to make a choice. Now.
