Rare even in the melting pot that is Havilon, caithuna tribes have settled on high altitudes primarily on the Great Chain, the mountain belt that divides Havilon into northern and southern regions.
Caithuna names are sometimes natural objects, weather phenomena, or animals, such as Cloud, Timber, Smoke, or Snake. Each caithuna belongs to a clan whose names are based on their geographical location, such as Bright Cliffs or Rumbling River.
The caithuna of Havilon are also known for their brewing talents. As a tribal race, the people often favor Thrizur and Draconiz.
