In the Oga mythology, tens of thousands of years ago, the gods all died in battle to resist the punishment of heaven and protect the earth. That day, the mountains and rivers changed color, and all things cried. Even the two moons in the sky changed their colors. The bright Xenia and the ice-blue Kawenna were all covered with blood red, like the blood of the gods, hanging in the sky. This is just a myth, no one has ever seen the double moon turn red.
However, in the eyes of the people of the Tuta family, the moon should be red. When the red Xenia shines on the earth, it heralds the birth of a new life in the Tuta family, and when Kawenna fades away from the blue, it is the death of a Tuta.
This is an agreement engraved in the bones and blood, with blood as the agreement and the moon as the witness. Life after life, it will never die.
