"The Ancestors originated at the river... the tribes gathered at the riverbank... we passed down the legacy along the river! ... Waters of all sizes... people of all sizes... finally reached the sea's edge! ..."
In the village of Krasop by the river, the tribal elder, River, is singing a ballad in front of the tribe's central hearth. This is a very small tribe known as the Swamp Tribe, even if you add up all the elders and young people around the hearth, there are only about a hundred people. Meanwhile, on the other side, the exploration fleet, consisting of armored Samurai and sailors, is nearly double in number.
The appearance of the exploration longship brought great shock and terror to this small tribe that migrated from upstream. Especially when about a hundred to two hundred armored and bow-wielding Samurai "with ill intentions" landed on the shore, surrounding the Swamp Tribe, the faces of many tribespeople all showed horror.
