Gastism

The Gastists believe in three gods: Pechi, the god of the sea; Ajia, the god of the soil; and Jafei, the god of the sky and father of the other two. Traditionally, Pechi and Ajia are not worshipped by the Gastists but are instead reviled. The Gastists believe that the world was formed when Jafei spawned the twins Pechi and Ajia, and that shortly after their birth, the twins perpetually fought with each other, causing much annoyance to Jafei. Thus, Jafei removed the left arms of Pechi and Ajia. By combining their arms, Jafei created the first human, whom he named Gasti. Jafei then commanded Gasti that he and his descendants are to prevent Pechi and Ajia from fighting one another. Jafei gave Gasti a fishing rod to control Pechi, and a spear to control Ajia. After the arrival of Gasti, Pechi became resentful of Jafei and began producing storms to limit Gasti's descendants to the islands of Casea and Brisa. Ajia also began to resent the descendants of Gasti and created her own group of humans to torment the descendants of Gasti. Thus, Gasti's descendants were limited to living on the coasts.

There are a few temples to Jafei in the south of the Caseic Federation, but they are not as prominent as the northern states' temples to Chae. Most Gastists don't worship Jafei, since they revile Pechi and Ajia. Additionally, Gastists are a decentralised faith, in that they have no central religious authority to resolve disputes. Thus, arguments about religious minutiae are commonplace amongst Gastist communities.
