Forestune is the god of nature and illusion. (Which checks out, because he's given disguises to certain mortals) His hair and wing tip color changes by season. Green, summer, Orange, autumn, Winter, white, Spring, pink. Every year, at the beginning of spring, mortals would have the Love Harvest festival, which they have to honor the 3 gods, Forestune, Sumire, and Lovarus. Sumire and Forestune are to honor the newly bloomed plants, and Lovarus to honor the season of love. There's dancing, pastries, pink larynx memorials, the flower dance, a ritual to please the 3 gods.
(He's Sumire's cousin btw. Also was Vulcantrus' best man at the wedding)
