Orthar told his story.
He had only been an insignificant octopus at the edges of the world, but when he became a Spirit Beast, he had believed that he had reached the peak of the world. Because of that, he had fathered a ton of children and simply decided to watch other beasts.
This life had dragged on until Gravis arrived one day and opened his eyes to the wider world. After that, Orthar told everyone about the River Tribe and how the Tribe grew with incredible speed until it eventually collapsed into itself. It had grown too quickly.
Then, he told his story about the time between the River Tribe and the death of his backer. Gravis' three kids hadn't really talked much with Orthar inside the Life Ring. Because of that, his story was also a new one for them.
