Klythonu-Vaati

The Klythonu-Vaati, meaning simply "offspring of Klython" in archaic Tuvai (cf. Thaedonu-Vaati), is a term variously used for all, or just some, of the wind-deities and elemental spirits of sky and storm which are the children of the elder god Klython. It may sometimes refer to all such beings, down to the weakest zephyr-spirit, but it is more often used specifically for the gods of the four seasonal and directional winds: Turomë, Nabhiru, Uatha, and Iraolis, gods of the north, south, east, and west winds respectively. These four are so much more prominent than any of the others that the "Offspring of Klython" is commonly understood to refer to them alone. They are the only ones that may be considered gods (and thus numbered among the Aiyu-Thani) rather than lesser elemental spirits. They are closely associated with the Qali Matra, the seasonal goddesses who are children of Epheos; each of the wind-gods is said to cause the changing of the seasons by chasing away one of the Qali Matra and heralding the one who comes after. For instance, Turomë, the north wind, brings winter by driving away Thuraeya at the end of autumn and ushering in Nimravis after him.
The Klythonu-Vaati (meaning the four wind-gods) are generally revered in Rhantashannu as a minor part of their father's cult, lacking temples or full-fledged priesthoods of their own. Their offerings and rituals will be conducted at subordinate altars in the temple of Klython, and their praises will be chanted alongside Klython's on his holy days. There are some exceptions to this, however; for instance, Iraolis is revered as the patron deity and protector of the city-state of XXXXX and has a huge temple dedicated to him in the city's center, and there is an important shrine of Nabhiru on the island of XXXXXX in XXXXX, attended to by a whole order of priests who dwell around it.
Outside Rhantashan Achuirea, the worship of the Klythonu-Vaati in any organized fashion is rare. They are sometimes propitiated by sailors and seafarers, but without much in the way of a formal cultus, and never ahead of the Khreianoa. In the lands of the Vanir-Vaati, they are regarded more as mere folkloric personifications of the wind if they are recognized at all. For instance, someone might say “Turomë is rushing down from the north” when the first cold gusts of winter are felt, but there are not temples or established priesthoods for them (indeed, such would be viewed with hostility and suspicion, given the prominence of Klython in the cult of Rhantashannu). 
However the Klythonu-Vaati are often highly regarded by druidic cults, such as those of the Vards, and some shamanic traditions among the Suagirs place great importance on them. The Suagirs call them the Tasharok in their language, which means "Rulers of the Four Winds", derived from the same root "tash", meaning king, seen in "Tash-Teshivan". This gives a sense of the reverence accorded to them. Nabhiru and Uatha are most prominent in their cults, unsurprising given the importance of the spring and summer grazing seasons to the livelihoods of the steppe-riders.
