Generally, Rangi's wife is Papa, though they are known throughout Polynesia, even when they're not considered spouses. The pair laid in a tight embrace which blocked light from touching the world. From them came the children Haumia, Rongo, Tāwhiri, Tangaroa, Tū, and Tāne. Some traditions may list some of these children alongside Rehua, Urutengangana, Aituā, Tiki, Whiro, or Ruaumoko, among others. Often, a war or skirmish between the siblings ends with them becoming the ancestors of certain concepts, habitats, mannerisms, animals, tools, or plants that they each represent. For instance Tāne became Tāne Mahuta, the father of birds and the forest, and Tū became Tūmatauenga, the father of humanity and its activities, such as war. Sometimes, Tāne Mahuta ascends to the sky after Ranginui to dress him with stars, who mourns for his wife every time it rains. Similarly, Papatūānuku strains in an effort to reach the sky, causing earthquakes, and the mist comes from her sighing.
