Íarus ap Gáeth, the West Wind, is the most gentle and favorable of the winds. He is associated with flowers, springtime, and procreation. In myths, he is presented as the tender breeze.
Íarus is one of the four quadruplet siblings known as the Four Winds, along with Anair ap Gáeth, the East Wind, Faitse ap Gáeth, the South Wind, the West Wind, and Túaiscert ap Gáeth is the cold wind from the north. Their mother is Déine ap Gáeth. Their father was a powerful creature from the Elemental Plane of Air, some say, while others claim their father was The Féth.
As demigods, the Four Winds cannot grant divine spells to clerics and priests. It is said, though, that they may serve as Celestial or Djinn patrons of warlocks.
