I'm going to try and set things straight here. I think I have been less than clear about my seeming agressive nature in response to this particular topic. I want it clear, I have absolutely no ill-will towards you personally, Arya. I am trying to understand your character's motivations. I think they could be a lot of fun to play out. There are aspects to them, that could make them not so fun to play out, too. Such as getting caught dissembling to fellow PCs. This kind of character requires a lot more work on the player's part. I share this out of previous experience.
Arya, Azura's backstory is that she's unreliable. It suggests that she is more than willing to play fast and loose with the truth in the way that is most convenient to her at the time. The Fixer and I, as players, have told you that her 6th magnitude Aegis is ineffective. Your character has offered to cast the 6th magnitude Aegis for the covenant[1], should she be accepted as a member. I think it's fair to say that those are the facts. These all things that are written, either in character or about the character in play to date.
Given those facts, it is entirely fair that I, as a player, question your character's motivation. Right now, it appears she is perpetrating a con. I am extremely aggressive in questioning you about your character's motivations because it helps me understand how to play Ra'am in response to Arya. In troupe style play, it's very common that players know things and then RP their characters as if they don't know them. Ra'am doesn't know Azura, but she's a Magus, and a Mercere (they don't prey upon the Order!) so he'll take her at her word. But, he's smart (Int 3), and he's extremely educated (Artes 6, Philo 4, MT 8+2), he's happily married, and he's not subject to her feminine wiles. There is a high degree of probability Azura's Aegis will be discovered as less than effective, it is fairly reasonable that Ra'am could even notice this right away, that's entirely up to amul. If Ra'am doesn't see anything that concerns him, I will play him that way. He'll happily go into the lab and learn other things, get it set up, spend one of his 7 possible seasons on refinement, whatever. However, if Ra'am sees things amiss, he will be all over Azura like white on rice, and not in a way she'd prefer. His family's safety is a high priority for him. Once that risk has been reasonably mitigated (to his mind), he's free to concentrate on other things.
I write all this out, because this is your situation as you've created it. I want to understand where you are taking your character. We (Fixer and I) informed you that your Aegis is ineffective. If Azura isn't completely forthright about the capabilities of her Aegis, we can only assume, as players, that it is your intention, as a player, that she not be. By your own description of the character Azura is dishonest, it means you have to step up and be extremely detailed with us about Azura's intentions, and trust us to play to her as she presents herself. It also means that should she get found out, you have to be prepared for actions that may be less than pleasant for her. Censure, fines, etc. and so on. Were I in your shoes, I'd expect no less be asked of me.
[1] In her proposal to Heims no mention of this being part of a WC was made, you offered that you would cast the Aegis. At this point, I don't believe anyone knows WC. To get to a WC capable for your level of Aegis, we'd have to have three people learn the 20th level WC, which would take 2-3 months. It's possiblethat Ra'am could invent a 20th level WC in two months while two others learn it from the lab text. If it's your intention that her Aegis be cast as part of a WC, you should make that clearer.
