How curious and intriguing!
Actually had something very similar in mind with my girl Nerissa.
That someone opposite of the Force Alignment of her would see something good through all of her barb-wired hatred and shattered soul and showing she's worth of love and care.
Also, she's of basically of royalty wealth with a nasty superior mind set and looks down on most others who isn't of equal or higher status due to her upbringing. So along with showing her someone would truly care and love her, I'm also looking into someone who in the end can show her, the errors of her viewpoints and mindset.
However, that is further down the line as I need to do her dark side arcs first. Besides due to RL stuff I haven't been able to really get the character off (though I plan on get her truly going after Sunday).
So Nerissa might not be the best pick right now, though if you haven't found a gal for Caedyn down the line, I'll be very interested to work something out.
Other than that, I'll be super down for them to just meet and at least get an enemy/riverly going if you're down! ^^
