In all of the Mortal Realm of Zerith, there is but one church, to the Dwarven god Moradin. The cathedral acts more as a guard tower to the mines, rather than a true place of worship. While many a dwarf can be found there, asking for the blessing of their patron before a days (or weeks) work underground, little credit or expectation comes of it. The truth of the matter is, in a world so dominated by arcane might, there is little room for other sources of power. Even the recognized faction of druids, the Tarin, are treated as lesser by the wizarding community, given that their power comes from the land rather than the ether.
While some shrines exist buried in places of the wild, or at the heart of some cities, most are relics from a time long gone rather than true places of worship. The gods seem to provide a resounding indifference to the world of Zerith, and the world responds in kind. In a world with such little divine touch, devout worshipers capable of channeling the power of the divine are even fewer and far between. Even the shrines, occasionally found in cities, or along the road, are often considered perfunctory; symbols of an ancient time of superstition and useless belief. To commune with a deity is a rare blessing.
Occasionally though, there is a true believer of a deity whose faith is so strong they can reach across the cosmos to the heavens and hells, and can channel the divine might of their deity. While often regarded in the same category of warlocks, their powers do not come from a patron, but of those who are divine or unholy, the actual gods who fought the primordials in the great elemental war before creation.
