The most important document is the creation story of Guadalcanal, "The story of what our ancestor in the beginning of the island Isatabu." About how Ironggali created the island of Isatabu (Guadalcanal). Ironggali is a spirit or god which lives in the air. When it came to the water it was called Isobotua – i.e. 'sitting on water' or 'floating leg'. Isobotua created the island and the life upon it: first 2 dos Laula (m) and Lauili (f) and then 2 humans: Kaputua and his sister Lavegauna. This text goes on to give the establishment of the four main descent groups or tribes of Qaravu, Manukiki, Koinahao and Lasi.
