Csanimh or Disxhipulina - literally "Old Way" or "training" in the ancient religious tongue, includes the numerous but fragmented folk beliefs in deities and spirits. Practices include divination through cloud-watching (adoratio nebularum or nephomancy), spirit communication, and shamanic healing. Some of their practices come from pre-Roman tribes, Catholicism, and the Vian religion itself, but most come from ancient local traditions.
The main role of the priest is to interpret the will of the gods by studying the path, shape, and interaction of clouds: whether they are flying in groups or alone, their color, position in the sky, what shapes they take as they fly, direction of flight and what kind of clouds they are. This is known as "reading the heavens." The ceremony and function of the ritual is central to any major undertaking in the Vian community—public or private—including matters of love, commerce, and family.
