Play the long game

Tempting as it is to simply take the girl now, you decide against it. If you took her now, then you would have to constantly work to keep her contained, lest she escape and reports of her violation draw the attention of Anari and the other gods. On top of that, if so many people love her, then it's safe to assume she would probably be fairly understanding if one of her priestesses were to forcibly have their oaths of chastity broken against their wills.

No, if you plan on eventually challenging the gods themselves, then you have to be subtle. People need to flock to you and abandon their deities of their own free will. That being said, there's nothing stopping you from planting the seeds of corruption and reap the benefits later.

Concentrating inward, you manipulate the shadows that make up your very form, and adjust those that create your voice.

"Why are you here?" You ask, your voice now a smooth, deep rumble that caresses the ear. The girl shivers almost imperceptibly and you smirk.

"Because you tied me up and won't let me leave?" She replies with more than a little sarcasm.

You chuckle and shake your head as you walk over to your crafting table and begin perusing the list of upgrades you can make to your room.

"I meant why would you - a priestess of Anari - enter my home? You've already been initiated. What would you have to gain?"

"Why do you care?" She demands. "Your just a monster."

You consider how best to answer her question.
