I find your lack of Katsu in your examples of Clan Icons disturbing.
Also, some emperor's stuff can be interesting, the story of Michio and his duel against the Fortune of Heroes comes to mind.
i can't name all of them! my love of katsu is well documented! i once photoshopped him into a picture of katsu curry! and while thats a very good example, the only problem with it is that at the time that it happened Daigotsu was dead.
i suppose i might as well give context: i have, for a while, been deeply frustrated with the lack of a coherent biographical sketch of Daigotsu. the wiki writeup is embarrassing. so i'm putting something together. the fiction provides a sort of framework narrative, but i need the meaty bits, around which i can build.
