Orlanth is the King of the Gods, Master of Storms, Death Wielder, and Bringer of Light. He is one of the Seven Lightbringers, and is the chief of those deities. His worship is widespread throughout much of Glorantha. He made the world what it is with his strength, and his virtues keep it that way. By right of his deeds Orlanth claims overlordship of the universe. He is the god of warriors, farmers, and rulers, all three.
Holy Days
Windsday of Movement week in Storm Season is the High Holy Day. Each season, the Windsday of Movement week is a seasonal holy day, as are the Windsdays of Sacred Time.
Additionally, Orlanth has a “floating” seasonal holy day each season. These holy days are determined by the priests of the cult and not fixed by calendar.
Subcults
The Orlanth cult has two major subcults: Adventurous and Thunderous. An initiate picks one subcult or the other when they join the cult of Orlanth—typically whatever subcult is locally favored. No additional POW sacrifice is necessary.
Other important subcults include Orlanth Rex and Vinga.
Only tribal leaders can join the Orlanth Rex subcult. The tribal king is the High Priest of Orlanth Rex for that tribe; the Prince of Sartar is High Priest for all the tribes of Sartar.
The Vinga subcult is an all-female warrior subcult that worships Orlanth in female form. Initiates must dye their hair red. It is otherwise identical to Orlanth Adventurous.
