Paisna is the oldest continuous religion, indigenous to Ganuo where most of its adherents live. It developed out of the pre-<<gyėša>> culture, mixing heavily during the first rifts-ganuoan dynasty, becoming a syncretic mixture of the two. It is possible to find two different Paisnaists that disagree on almost every possible issue in the religion, due to continuous branching and a lack of universally agreed upon canon. Paisnaists tend to gather at places of worship whenever the mood strikes for intercessions from the gods in personal affairs, as the temples have more supernatural power than the rest of the world, putting them closer to the gods. The process of establishing a new temple is very involved in order to bring the power from an already existing temple to the new one being established.

There is a vast array of gods, of which individuals often have one that influences their life much more than the others. They all come in pairs, a version to rule over Pavala and a version to rule over Haki. The Paisna gods are usually regarded as impersonal forces that can manifest in bodies, and more common gods often have a number of different bodies that they can manifest as. Gods can manifest new bodies whenever they wish. Who a person's most influential god is, is seen as the god choosing a person.

Occasionally, people claim that a god has chosen to manifest as them and they are treated as having become a body of that god, but if that person begins behaving in a way incongruous with that god, they may be murdered, and that god would need to manifest a new body. When this happens, Paisnaists believe that a god who is an enemy of the god who is in that body is fighting over the body, entering it and attacking it, causing the person who is a god to behave erratically.
