Seiun Clan

The is a now extinct clan, known for its intriguing and unique techniques involving elements and illusions rarely used by shinobi. Some of the clan members were also provided with a genetic inheritance that allowed them to have a thorough knowledge about the human mind, being able to make innovative discoveries and store various information easily (like a photographic memory).

The clan was known in the Land of Lightning, shortly before its extinction, but Kagemori Seiun (one of the most famous members of the clan), became known after being named Tobikage of Tobikakurenai Village, which was in the Land of Recoil. Although the circumstances that led Kagemori to move to a country so far away from his clan's origin country are unknown.

The clan was exterminated on the excuse of "knowing too much", since other clans, villages and countries argued that this thorough knowledge of the Seiun clan was a threat to the world, because its members would be able to usurp any leadership post. Other versions also said that the clan was plagued by something similar to the, called the Curse of Ambition. However, this ideal never was proved.
