So, just to repeat, this actually is about SA against Asylon? More or less how Glaumring's been saying all along but been dismissed as a crazy man for it?
No. Neither Glaumring nor Feylonis really know anything, they're both just seeing what they want to see and neither one has any evidence to back up their claims. They are making assumptions that are driven by their respective biases. That or Glaumring is just making things up for fun, I can never tell with him.
All it really boils down to is that Glaumring's character got overconfident, raised the ire of the wrong people, and made several mistakes. Those people then exploited his mistakes to organize the current war. There's no conspiracy, it's not a religious thing, and Allison actually had very little to do with it beyond baiting Asylon in the first place. She probably assumed that if she could provoke either Terran or Asylon into going too far, Astrum would intervene, and she assumed correctly. Terran was too smart to fall for it, as evidenced by their careful diplomacy with Astrum, but Asylon walked right into it. That's Allison for you. She's very crafty.
