From the moment they assumed humanoid form, mankind had walked a world of strife waging war against one another. The ground was stained with blood, and as if drinking it in, the Divine Tree took root in the earth. In time, the Divine Tree bore a single fruit, and a clan migrated from another world in search of it. They were the Ōtsutsuki clan. Kaguya, leader of the Ōtsutsuki, ate the Divine Tree's fruit and became the originator of Chakra, and with that tremendous power subdued the world in the blink of an eye.
→↓ The towering Divine Tree. It bore a forbidden fruit that would bestow power to whomever ate it.
Rule
She who ruled alone and coveted all Chakra.
Ōtsutsuki Kaguya had brought an end to the turbulent times. Dubbed the Rabbit Goddess, she received the blessings of the people and gave birth to twins.
↓ The birth of Hagoromo and Hamura. Kaguya's Chakra had become dispersed.
However, Kaguya ruled by herself and often resorted to cruelty. The Byakugan, the Sharingan, and the Infinite Tsukuyomi—these jutsu wielded by Kaguya were regarded with fear, awe, and reverance by the people. At some indefinite point, the Rabbit Goddess had instead become known as a Demon. Then Kaguya found herself ruled by her own desire to possess all chakra.
Moon
The Ōtsutsuki brothers used the power of Six Paths to seal Ten Tails.
Kaguya's desire to unite all Chakra eventually turned her against Hagoromo and Hamura, her own twins, to whom she had dispersed her Chakra while giving birth. Devising a plan to absorb their Chakra, she integrated with the Divine Tree and challenged the twins to battle...
↑ The Ōtsutsuki brothers fighting an incarnation of the Divine Tree, Ten Tails. In truth, they were also doing battle with their mother.
The twins, assuming that Ten Tails was an incarnation of the Divine Tree, and that it had attacked them to recover the Chakra from its stolen fruit, met it head on. After a desperate struggle, they invoked Six Paths Planetary Construction. Transforming it into the moon, they sealed it away.
↑→ The husk of Ten Tails, the Gedō Statue, was sealed in the moon. Hamura took leadership of the clan and decreed that they would stand guard over the statue.
