Long ago, at the beginning of everything, there were three siblings. Two were men, and the sister, named Onhiamuaçabê — or simply Uniaí — was a young woman of rare beauty. She owned a magical place called Noçoquém, where the most incredible plants grew: food, medicines, and materials for crafts. Uniaí knew all the secrets of that place and gradually shared her knowledge with her brothers. In Noçoquém, she planted a Brazil nut tree so immense it seemed to touch the sky.

In those times, animals were like people, and many wished to marry Uniaí. However, her brothers wouldn't allow it, as they wanted her to continue taking care of everything for them. One day, a snake decided to win Uniaí's heart. It spread an irresistible perfume along the path and, upon smelling it, Uniaí became enchanted. Encouraged by the compliments, the snake revealed itself and expressed its desire to marry Uniaí. In those days, mere desire was enough to conceive children, and so Uniaí became pregnant.

Uniaí's brothers were furious at the news. Fearing they would lose their sister's help, they banished her from Noçoquém. She left and built a house near a river. There, she gave birth to a strong and beautiful boy, whom she raised with all her love. As the boy grew, Uniaí told him stories about Noçoquém, his uncles, and the majestic Brazil nut tree. Fascinated, the boy one day asked to taste the nuts he had heard so much about.

Uniaí explained that it was dangerous, as her brothers had placed guards at the Brazil nut tree: an agouti, a parakeet, and a macaw. Even so, the boy insisted and went there with his mother. Later, he returned alone to get more nuts. However, the guards alerted the uncles about his presence, and the brothers ordered a monkey to watch the tree and eliminate any intruder. The boy was caught by surprise and, struck by arrows, fell lifeless.

When Uniaí noticed her son's absence, she ran desperately to Noçoquém. There, she found the boy's body. Her weeping was so intense that her sorrow transformed into strength. With determination, she planted her son's body in the earth, proclaiming: "From you will grow the strongest plant, which will heal men and give energy for love, war, and life."

From the boy's left eye grew the false guaraná, called uaraná-hôp. From the right eye sprouted the true guaraná, the uaraná-cécé. This is why the guaraná fruit resembles a human eye. Days later, Uniaí returned to see the guaraná. The plant was lush, laden with fruits, and beneath it she found her son alive again, strong and joyful.

This boy, reborn from the earth and guaraná, became the first Indian of the Maué tribe, a symbol of strength and vitality. He is considered the ancestor of the tribe and the personification of the power that emanates from nature and life that renews itself.
