Tatsu Clan

The Tatsu are a hidden clan that have been residing and ruling over the Hidden Ice Village till date. The tatsu clan was formed at around the same time as the Senju and Uchiha clans. Though small in number, they are highly skilled and according to Ryuichi have the strength to hold their own against most current clans.

Origins
It is stated in the clan records that the clan was created by Rikodou sennin’s third and youngest child, his daughter. Born with the Rinnegan and the ability to mould ice, she was unlike her brothers. She mastered her powers at a young age and had a vision of the future. She saw that a time would come when the Senju and the Uchiha, her brothers’ descendants would battle like never before and finally find temporary peace before one would be almost completely destroyed. She saw that sometime after this the world would face a threat like never before which could end the world as we know it and begin an eternal age of darkness.

She also saw that only when descendants from all three of Rikodou Sennin’s offspring’s united would there be any chance of survival for the world. But she knew that the animosity between her brothers could not be subdued. So she realised the best way would be if her line survived and when the time came reunited the three lines, as she had also seen the Rinnegan being the tool of this reunification. She then realised that her line must survive so the when the time came the sage’s eyes could return to the world and help restore peace.

So she left her family and with her trusted friends and followers went into hiding. She travelled to the current north of the Fire Country and in a beautiful and bountiful valley she founded a village which ultimately came to be known as the Village Hidden in Ice. Using her skills she sealed up the valley and raised great mountains all around so that the valley would be nigh impossible to find from outside. It was here that she founded the Tatsu Clan.

Elder Line
Over time the clan grew and mixed with other members of the village. Rikodou Sennin’s blood got diluted and its power waned but there was one family in which the blood flowed as strong as in the sage himself. Born from the Daughter’s eldest son, this line was stronger than the rest and possessed the Ice Techniques Blood line limit like their ancestor. This above gave them great power and over time they came to be known as the Elder Line of the Tatsu Clan.

Rinnegan
Every four or five generations a Rinnegan user was born into the Clan. Though often born into the Elder Line it was not uncommon for one to be born within the rest of the clan. With a Rinnegan user born into the clan every few generations, they had a proper set of training procedures and protocols to follow whenever a Rinnegan bearer was born in the village. Given the best training the village had to offer, all the Rinnegan users were brought up under the assumptions that they might be the one seen in the prophecy.

It became customary for them to take over the village’s shinobi’s when they turned 18 and ultimately take over command of the village.
