Ava, a previously closeted dom

"Okay so I'm Ava; very much gay, not too many interests, no real friends mostly due to being shy during school. Also kind of excited by the idea of this ring."

"Well as of right now you're probably the most powerful person in the world."

This opens up a lot of things; but first, questions.

"What if a were to use the ring on myself?"

"It'd still work, you'd just be aware of the changes and be able to revert them at any time."

Well that's reliving.

"What if I were to use it on you?"

"As I am a manifestation of the ring I cannot be influenced by it."

"And what counts as a woman in the rings eyes?"

"It mostly goes by identities; strong, dominant, masculine male identifying people are less likely to be influenced. The only reason why I say women anymore is because I'm reading off a script written when the ring was made and considering the person who made it is now long dead, and it has to be them to change it, it can't exactly be updated."

Explains why she was so bored reading out what the ring does you suppose.

"Alright, and if I were to make someone strong, dominant and masculine. Would I be able to change them back?"

"Yes, that would still be possible. Anything else?"

"I can summon you at any time right?"

"Yes; I'll also tell you when a person is likely to be affected by the ring and try and warn you against things that got previous ring bearers killed."

"Perfect thanks."

You feel the ring grow slightly heavier as she's sucked into it. Right, now to make your next move.
