Gaile Laagh
More often called steaming or breathing, Gaile Laagh is a coming of age ritual for the Rathi people, wherein a youth sits in a small tent and boils a pot of seawater with a wyrm within it, usually a snake or salamander. This supposedly grants them visions and wisdom about a particular issue in their life or that of their family, which they will share at a celebratory ceremony that night.
Though by tradition this ceremony was restricted to boys, in the last hundred year or so it has come to be assumed by girls as well, as more and more the Rathi people come to rediscover the relevance of priestesses in their ancient customs before their subjugation to the Ethels.
Many Rathi do not live by the sea, and as such many will boil river water or even swamp water, though especially devout (or wealthy) youths will take up pilgrimages to the sea.
History
Gaile Laagh is said to originate with one of the many myths of Laoch Torin the Dragon Slayer. Among Rathi custom, Laoch Torin slew the great dragon Itherion, and the seas boiled as the great beast collapsed under the waves. The fumes of this boil were said to have gifted Laoch Torin with visions and magical powers. Some versions of this myth name him the first King of Rath, or the forefather of the Kings of Rath. Some versions say the Sunset Siren was born from Itherion's dead gullet, or that the boiling seas summoned her.
