There's a link on the very first post.
Anyway, here's some ideas for a faction trait,s since you said you're looking for more.
How about a trait that removes shields replacing them with specific off-hand weapons. Could be some new ones in addition to off-hand versions of already existing weapons. Not sure what you'd call it.
Another idea--Wild Magic, which causes each city to have exactly 1 essence, regardless of a where it's built. Improvements that add essence would still work as normal. Could also through in that each city produces an extra manna per turn too, if that's not powerful enough.
Maybe Inspired, which causes more knowledge to be produced for research than normal, and allows the faction to get more benefit out of knowledge received. Haven't crawled through the files yet, so don't know how possible that one is.
For negatives, maybe one that would make the faction unable to use mounts of any kind. Not sure what to call that one either.
Maybe another one that causes it so that town choose their specializations randomly. Call that one Independent Cities maybe.
