Particular thanks to Jeff Rients, from whom I pilfered Omnia and the Frog gods.
Chief god, general grumpy sky dad and master of lightning, Aon (or another suspiciously similar deity) is worshiped in almost every human culture on the Coin, although they vary as to which goddess is his wife and queen (leading to some interesting and very heated arguments). He is typically shown with two animal companions, although what these are varies - in the Hublands, he is shown with an owl (representing cunning) and a bear (representing badassery), while in the League heartlands he’s more often shown with an eagle and a lion. Combinations of these creatures might be considered holy gifts (griffons) or profane abominations (owlbears).
The primary goddess of rivers and fertility around the Friendly sea, and often depicted as the wife of Aon. Hippopotami are considered holy animals by her faith, and ancient depictions of her often show her as a ponderously-proportioned anthropomorphized hippo, although the modern church frowns on this. They also frown on the worship of Khadahan (see below).
A martial goddess, Areena’s creed promotes physical and moral purity, as well as crusades against evil-doers (or, if there aren’t any evil-doers around, foreign faiths), and the justice of trial by combat. There are several orders of warriors devoted to her, in the League and in a few other countries. Invariably, they are single-gender groups. Unicorns are considered holy to her faith (whereas everybody else thinks they’re crazy and dangerous). Her followers heartily dislike the followers of Frikk.
Another god of rivers, as well as sunbathing and long baths, the Crocodile-headed Khadahan was mostly only worshiped in Aratha until a recent miracle at the temple in Al-Harraj unified the splintered factions of his faith, and expanded his portfolio into the realm of fertility. His faithful are now trying to spread his worship around the Friendly sea, setting up bathhouse-shrines in several major cities. As a result, they’re in direct competition with the church of Hippatara.
Goddess of war, alcohol, and carousing in general, Frikk’s faith is main popular in the Hublands, where the locals really appreciate those things. Where Areena’s warrior-clerics promote purity and honour, Frikk’s worshippers are encouraged to brawl, drink, sing loudly, and do whatever they want so long as it doesn’t hurt anybody (unless those people are your enemies, in which case, go right ahead). Areena’s faithful are generally considered to be too uptight, and should be mocked and needled wherever possible. Chainmail is considered a gift from her to mortals, and holy folk almost always wear it (often in far smaller quantities than would be considered sensible or proper, to show their faith in the goddess).
The Solar Dragon
The Solar Dragon is sort of a borderline Dark God. On the one hand, his Sollais faithful abhor all other dark gods. On the other, they abhor ALL other gods, claiming them false and demonic, while periodically sacrificing virgins and enemies of the state to him (by guillotine). The Sun Prince of Solielle is considered to be his chosen leader on the mortal plane. Images of a more feathery version of the Solar Dragon have also been found on some old temples in Zwuyala.
Another strange and unpleasant god from the jungles of Zwuyala, Iggujugglyoo, also known as He of the Thousand Teeth is a bloodthirsty god of carnivorous dinosaurs, particularly velociraptors. Little else is known about him, except that his worshippers tend to utterly crazed.
Rzngl the Unvoweled
Depicted as an elf with the heads of two deer, each able to shoot burning rays from their eyes, this demon prince (or princess, it seems to vary) enjoys blood sacrifices in a pleasantly woodland setting.
A goddess of temptation and corruption, Tormentara offers mortals their wildest desire, but always finds a way to take that desire to such an extreme as to be horrifying for the unfortunate that caught her attention. Her worship is both open and prevalent amongst the Dark Elves, who hope to placate her evil whims.
A demon god of earth, stone, monsters and deathtraps, Gi’Am’s dungeon-temples are a favourite target for adventuring parties. Which seems to be just the way he likes it...
The Frog Gods of Chaos
Not a single god, but a multitude of extra-dimensional amphibious horrors devoted to corrupting or destroying the universe as a whole. Thankfully, they’re so chaotic that they often work at cross-purposes.
God of sewers and plumbing, Urinor is among the youngest gods on the Coin, his faith only having existed for a few decades, at most, since his slightly unhinged prophet, a dwarven adventurer, began spreading his word. He mostly receives prayers in the form “Oh God, I really need a privy”.
Different cultures differ as to whether Roadael is a demigod, a saint, or an archangel, but whatever the case, he is the patron of porters, hirelings, and servants, and is said to aid the other gods in preparing for manifestation on the mortal plane.
Goddess of Everything Not Covered By Other Gods. As a result, the things Omnia is responsible for are strange, eclectic, and generally only come up in very unusual and specific situations. Her followers are rare and a bit weird, but are mostly quite nice, except for an shadowy (and insane) cult that wishes to destroy all the other gods so as to expand her power.
The Bird God of Birds, Kwaaak’s faith dwindled to almost non-existance a thousand years ago, after he went insane over wizards developing flying brooms. His church was resurrected recently by an elvish princess, and is making headway promoting him as the (much more sane and reasonable) god of airborne travel in general.
