"This request is for a technique the above character can use to `reflavor` the possession subtalent as well as to use the souls that they are possessed by in combat in an indirect capacity, such as using the souls to explain how certain strange techniques like Negotiate and Steal function."

Could you give more examples of anymore abilities you would use as this reflavor? Negotiate and Steal are most likely fine if they were just those two alone but on the nature of soul-keeping with the reason as "antagonism" could you also describe examples as to how you would roleplay an antagonist with the ability to manipulate souls at the level you are applying for?

I could see maybe a Reaper or Apertaurus gone rogue from their original purpose as a race doing a devil/contract theme with spirits at least, you wouldn't need an app for that though.
