... A very long time ago, A Ten Tailed Beast, called the Juubi, ravaged the lands of Equestria. It was a walking disaster, and each of its Ten Tails could cause catastrophes and natural disasters. It was unstoppable. But one day, a unicorn named Starswirl, the Bearer of the Rinnegan, and his brother, Starfall, Battled the Beast for 182 Days and Nights. Eventually, realizing they couldn't defeat it, they resorted to seal it. Starswirl sealed the mighty beast within himself, ending the threat of the Juubi.

Years would pass, as Starswirl went on to have children of his own, These were his Sons, Starwave, who would go on to establish the Senju Clan, and Starweave, who would go on to establish the Uchiha Clan.

As Starswirl grew older, so did his time run out. He knew that with his death, the Juubi would be free to wreak havoc upon the world once more. So, with the amazing power of his body and mythical power of his eyes, he split the Juubi into 9 fragments and created the 9 Tailed Beasts. From the One Tails to the Nine Tails. Shukaku, Matatabi, Isobu, Son Goku, Kokuo, Saiken, Chomei, Gyuki, and Kurama.

When it came time to choose between Starswirl's sons of who would inherent his Will to spread ninshu to the world, he chose Starwave, as his Ideals revolved around Working together with others and find peace through Understanding. Starweave, however, did not agree with his father's decision and directly challenged Starwave and Lost. Starweave, in order to gain the power to defeat his brother, Killed his closest companions, evolving his special eyes, called the Sharingan, a diluted form of his father's Rinnegan, into what would eventually be dubbed as the Mangekyou Sharingan.

Years had passed, and Starswirl eventually passed away. Before he did, he gave a Prophecy to the Tailed Beasts, who Starswirl had come to see as his own children as well. That one day, a savior would be born who would one day Reunite them

The war between Starwave and Starweave continues for years until they eventually perish at each other's hooves. From that day, the Senju and Uchiha clans would inherent their Ancestors grudges, and become Swarn Enemies. These would come to be known as the Warring State Era. Many clans have sprouted up as years passed. Clans like the Uzumaki Clan, Nara Clan, Hyuga Clan, Inuzuka Clan, Akimichi Clan, Yamazaki Clan, Aburame Clan, Kurama Clan and many more clans.

As the years passed, two female fillies met each other. One so bright she was compared to the Day and Sun, and the other do dark se was compared to the beautiful Night and Moon. These were Celestia Senju and Luna Uchiha. They grew up meeting each other, not knowing they were from opposite clans. They grew close like real sisters. But when the truth came out, they felt conflicted. They should hate each other... But they didn't.

More years would pass before the Two of them, now heads of their clans, formed a Truce between their clans.

They would eventually go on to establish the first ever Shinobi Kingdom. They named it, Canterlot.

As the years went by, more and more clans joined Canterlot. This prompted others to eventually form their Own Ninja Kingdoms. This led to the 6 Great Equine Nations. Canterlot, Dragon Lands, The Crystal Empire, the Changeling Empire, Griffonstone and Sea Kingdom.

Wars were started due to Canterlot's prosperity, but time and time again, Canterlot emerged victorious.

The Tailed Beasts went into hiding after the dark side of ponies was revealed. Some hid away. Some found willing hosts. Some befriended Ponies, Dragons, Changelings, Griffins, or Seaponies.

Three Shinobi Wars has passed. And each and every time, Canterlot emerged the Victor due to their strong belief in Comradery, Teamwork, and Friendship.

This brings us to the Present Day.
