So, I'm thinking about putting together a Solar martial artist for a game I'm playing in that currently has too many inter-party conflicts - In a nutshell, the roughly Chaotic neutral sorceress (me) is getting into waaay too many arguments with the VERY Paladin-ish Dawn caste. Sorry about the D&D terms, I really am, but for the example, it works.

Anyways, I'm thinking about putting together a probably Night Caste proficient in Solar Hero Style, with a fair amount of athletics charms on top of that. Want to get into the area of God-Speed Steps, with the idea of a martial artist who is just blazing fast, his style being to hit a single enemy from multiple directions nigh-simultaneously.

Personality probably pretty curt, to the point. Not non-talkative, because that's boring to play, but he doesn't take crap from people.

Not many details about this character besides that are set in stone yet.

Anyways, I'm looking for a suitably awesome motivation, and was hoping you lot would help me out with some suggestions. What do you think?
