Dwarven religion as a whole tends to be rather homogenous throughout the world. While there are some variations between regions, these are generally outweighed by the similarities. Whether the chief dwarven deity is called Moradin, Torag or something else, most scholars agree that they are in fact the same being, worshiped in different ways in different regions.
Of course there are still a few exceptions. One of the seven races of dwarves has mostly fallen into devil worship. Others have adopted the religions of local cultures, or at least adopted some of they’re practices into they’re own faith.
