[@Buddha]So as i rework both the clan and the history, I'm thinking of making a relation between one of the sects of the clan and the Uzumaki clan. Not a blood relation, but a symbiotic one. Uzumaki clan try to use their fuinjutsu specialties to help them control their rages, they use their abilities to help defend and protect the Uzumaki Clan.

I'm thinking of making the Kekkei Genkai a curse from the White snake Sage in Ryüchi Cavern, having cursed the progenitor clan and those who hold his blood because of some transgression they enacted in order to gain the Snake sage's power. You know the whole 'get what you wish for, but not in the way you wanted it' kinda deal. Anyway, they got the power, but soon nearly killed each other or where hunted down as their rages and power proved to be their undoing, leaving nothing behind about their clan but rumors.

The clan exists, but have secluded themselves in different sects, one for each of the elemental nations and with different philosophies on how to deal with their curse. In Mizu no Kuni, where I'd assume the Uzumaki clan to originate from given their name, they seek to better control their rage, so as to harness it properly, and the way they do this is through Fuinjutsu with the assistance of the Uzumaki clan. This provides a more probable source for the chakra regulating eye-patch than random fuinjutsu guy.

Anyway, long story short, was there someone already working on an Uzumaki character and thus the Uzumaki clan? If so, I'd want to be sure to clear this all up with them first, as well as collaborate on it with them a little to make sure we're on the same page with out stuff

Side note: Since we know of two Uzumaki's who have possessed it(Karin and Kushina) would the chakra chains be considered a Kekkei Genkai for Uzumaki women and not just a special trait? This is just a curiosity/backstory/plausibility thing and has no bearing on my character's abilities or anythin like that. He's strong enough as is, don't need to try and cheese in something else or try to replace with something that I don't really understand the full applications of.
