I'd like to put Crixus Domitius here. One of the most influential and dominant character to ever have walked Dwilight.
I'm... not sure I agree. To me, he seems third-rate, at best. A few of characters have had a lasting impact on basically the whole continent, a handful have had an impact that was great more more limited in scope in terms of either time or how much of Dwilight, and, Crixus...? Has he ever been relevant outside of Swordfell? He may have all the titles Swordfell has to offer, but Swordfell has never had any continental or even regional relevance that I can think of. Next to Mathurin, Allison, Dragomir, Jonsu... he sounds like a nobody to me.
