Worship of the Sovereign Host takes many forms in different cultures, but the religion as practiced by most of the humans of Khorvaire can be traced back to the kingdom of Pyrine. The Pyrineans placed great value on wisdom and philosophy, and Pyrinean tutors and priests served in courts across Sarlona. However, faith failed to protect the Pyrineans from the quori. During the Sundering, the Pyrinean church was torn apart by schisms and heresies, and Pyrine was crushed by the forces of Nulakesh and Ohr Kaluun. Although most of the libraries and churches have been destroyed, explorers might be able to find hidden vaults of knowledge or ancient shrines providing new insight into the worship of the Sovereign Host. 

The Pyrinean love of philosophy has made them devoted to the Path of Inspiration—although not as aggressively fanatical to the doctrine as the people of Corvagura or Nulakesh. Many Riedran clerics come from this province. Pyrine is one of the most peaceful provinces of Riedra, and the Thousand Eyes and the Harmonious Shield have a reduced presence in this region. Even though they are dedicated to the Inspired, Pyrineans are not as hostile toward foreigners as other Riedrans are; many Pyrineans enjoy having the opportunity to proselytize and discuss their faith with outlanders.
