What Rough Beasts
Many things wander the world. Some are not entirely mortal, nor exactly divine. The man dressed all in leaves who offers you a pact sealed in blood, the creature of living flame that dwells inside the volcano, the wraith of a long-forgotten warrior, or the great wolf with eyes of blue flame that stalks the deepest forest—these are the spirits. Neither good nor evil, human nor god, they can be as innocuous as a small hob that sweeps out houses at night in return for a saucer of milk, or as awe-inspiring as the Old Man of the Mountain who shields the village at his base from all harm…until they forget an offering…
While priests and priestesses administer the will of the gods, the spirits have no organized clergy. In spirit-rich areas, a shaman, medicine man, or wise woman may act as an intermediary between the mortal and spirit realms, but even where such a figure is absent most people are raised with enough folktales, old rhymes, stories, and old wives recipes to be able to get by. Usually.
While there are far too many spirits to ever count, the most powerful and far-reaching ones are tied to great terrain features. Each of the Sacred Mountains (Mt. Daulos, Mt. Ada, and Mt. Issos) have an associated spirit, usually referred to as “Lord” (e.g. Lord Daulos). Each of the major rivers (the Scaphone, the Metos, and the Salcus) also has an attendant spirit, usually referred to as “Lady” (e.g. Lady Metos). Those who dwell near each of these features have various festivals, rituals, and rites to curry favor with their guardian spirits, as well as any lesser spirits associated with their respective areas.
