User blog comment:BadDesperado/"Swain's" Duel Against Keiram Darkwill/@comment-3446451-20130509225802/@comment-5927074-20130509230526

That's exactly the reason I thought it would be LeBlanc.

This wikia is the only place where I've read that Swain is a former member of Black rose. Atleast I haven't realized it reading through the lore.

But the lore does indicate that LB and Swain are still allied, at least.

It says that on LB's judgement. It also says something about Swain sacrificing so much for something.
