Why yes I can! One of the things I've always had fun with with Rasani is her temper. Not many know she's got it, but it's explosive and impulsive. In this case, she actually told Chakrasul that she would see Her (a God mind you) beheaded and then killed a special butterfly she has roaming about.
So, to get back at her, Chak messed with one of her Knights! Trapped in his own mind and tortured and his wings replaced with butterfly ones, all very creepy and awesome. She knew that just killing Rasani wouldn't do anything, but seeing one of her Knights suffer? it'd been eating Rasani alive for months.
The admin involved with this arc, there's another piece with Damariel that I wish I'd saved where he tests the 'save him or kill him' sort of thing, were all wonderful. It's truly a Templar struggle, doing the right thing no matter the pain it causes you, and I think it wa a lot of fun!
