Hi Jill, and thank you! I swear, I'm not as crazy as all these comments make me seem.
Charon would definitely be someone Pestilence would find interesting, and if you're up for it, perhaps they already know each other from somewhere? She'd find Eve a bit plain and boring, sadly. Nimue would definitely seem intriguing to her, just like Mordred, while Anteros might be too intense for her to actually enjoy being around. I think she'd consider Raven a little brother of sorts (even if he is sometimes an annoying little brother), so he gets away with much more than others do. Still, he's no Horseman. Sorry, Raven. I DON'T KNOW ABOUT THE OTHERS, SORRY :(
