There is no universally accepted religious belief, except in Anhi, where the government enforces the worship of Torlan and Zahkaar (Fate and Chaos).
In Ontil an eclectic set of gods are worshipped or not worshipped, especially (under the influence of Coranian exiles from the Wardlands) the Strange Gods, including Death, Justice, Peace, Misery, Love, and Memory.
In the Wardlands at least three gods, or three aspects of one god, are worshipped: the Creator, the Sustainer, and the Avenger ("Creator, Keeper, and King").
The dwarves of the Wardlands evidently assent to these beliefs. (At any rate, they have been known to swear by these deities.) But they have another, perhaps an older, belief in immortal ancestor spirits who watch the world and judge it from beyond the western edge of the world. The spirits of the virtuous dead collect in the west through the day and night, and pass through at the moment of dawn, when the sun enters the world and the gate in the west is opened. Spirits of the evil dead, or spirits that have been bound in some way, may not pass through the gate in the west. Hence, dwarves each day (at sunrise, or when they awake) praise the rising of the sun and the passage of the good ghosts to Those-Who-Watch in the west.
