Also I'm trying to think of things that would draw Lord Ahrimen's attention, but am drawing a huge blank. Would you mind sharing some examples? Please and thank you!

Just off the top of my head, I would think that something that might catch his immediate attention - at minimum - might be that one of the initiates of the Knights of Valance now both has a Demonic familiar whispering in their ear, and now also has begun doubting the order she practically grew up in. Now, that alone I don't think would earn much from him - his attention, definitely, but I don't think he'd scoop her up just for having a few doubts either - but if, say, Katrina begun seriously deviating from the Knights in open defiance, then he would definitely take a keener interest. 

Going off of that, i'd think that her coming into direct conflict with the Knights of Valance would be sort of inevitable: I don't think that it's something that they would take lightly to her simply up and leaving due to having sudden doubts. But if she kept to her guts and openly defied their pleas - or threats - to return to them, then that might prompt the attention of Ahriman more directly.

That's just an example I thought up, but something similar to that sort of premise might work out.
