In Kiwai belief, the afterworld, the land of the dead where life is similar but easier than life on earth. Adiri used to be a barren place, inhabited only by Adíri and his daughter Díviro. When Sído, the first man, died he opened the way to Adiri. Sído married Díviro and from their union came forth the various plants which grew in the afterworld. He then rubbed his teeth with wood to produce fire and proceeded to built a vast house, several miles long, which became the residence of the spirits of the dead.
