So, Ayala might be Nio's incarnation, unless it is a trick? I actually was somewhat suspicious beforehand that this could be a thing. It just seemed like a thing that a cruel GM would do to try twist a knife further in the playerbase's wounds (and to make the story more interesting, of course). Anyway, heavily in favor of continuing our negotiations. What we get already for "free" is pretty good, and continued exchange of favors could be quite useful, as would be keeping in contact so that we can work on converting them further.
[X] Negotiations
-[X] Concession B: You will be able to tell select people who you trust (Zao, Pearl, Moon) about the Infernals.
-[X] Concession S: Ayala will agree to perform one Sorcerous Working for you, at a cost. Terrestrial Workings of Ambition 2 or less can be performed for Resources 3, you provide any needed materials. Celestial Workings of Ambition 2 or less can be performed for Resources 4, with the same conditions.
-[X] Reciprocal exchange of services: Assistance with assassinations on a one-to-one, unique services (Prophet of Seventeen Cycles/Sorcery), intelligence on threats to Creation.
No, we should simply learn Sorcery. Problem solved. We could have done that at our last vote. Until we do learn it, however, I am opposed to taking choices that disincentivize it; if killing our enemies is beneficial, enjoyable, and helps us learn Sorcery that's great. Until then I'd prefer to simply avoid alternate methods of accessing Sorcery (unless we could get a consensus that we'd get Sorcery regardless of practical considerations), and once we do get it I'm fine with Solaroid Sorcerers.
If it helps, I'm strongly for getting Sorcery the next time we get to have the chance, now that we have PoSC out of the way, with the added incentive of Ayala not being our direct ally, at least for now.
