I thought I deleted this thread but I guess not, huh. I deleted my graphics cache and reinstalled, now there's at least coat of arms, I think they're from the submod I was talking about. Some previous version just had black CoA's, or my game was just screwed up.
By Valyrian-esque I meant things similar to the Targaryen and Velaryon CoA's. The current CoA's for Valyrian houses have some weird color issue where it almost seems like each color used is just a transparent colored slide overlayed over the entire CoA's so everything kind of just blends a bit, but at least they're sort of Valyrian themed. Volcanoes, Dragons, Fireballs, etc. etc.
