Finally really breaking into Paisly, and with a very experienced priest to boot, would, methinks, be of great value to SA.
I don't want to be a mere puppet... if I join, I would need some assurances to be rather high up. Switching faiths will also result in a loss of oratory skill I believe, which would be a pain (I'd hate to be a less effective ambassador). I'd also need to, you know, actually read up on SA, which I never got my head around to doing.
And Machiavel has so much history with VE... he's the one who brought it to D'Hara, Barca, and a wee bit to the South-East. He used to be a very active proselytizer. He was the only priest south of Caerwyn for very, very long, and he turned D'Hara, at one point, into a nearly 100% elementalist state. It wouldn't feel right to turn back on that. And I can't hide I've used Verdis Elementum against Aurvandil of a few occasions, though I did use restrain to prevent backlash against the followers who do live there.
It's a scary leap. If I jump, I can make D'Hara a strongly SA realm. Which obviously comes with its load of advantages. Though it would change the realm forever.
And dammit, I don't have time to read up all of SA's pages! Not now, at least. Gotta say that's probably one of the biggest factors. It's likely to happen, though, one day. With Aurvandil betraying us, and the Lurias joining it more and more, the reasonable thing to do sounds like joining it more ourselves as well.
