Midgard has two pantheons that co-exist peacefully (though they did once fight a war against each other). The Vanir, living closer to Midgard, are gods of more earthly things. The Aesir, being less connected to Midgard, rule over more abstract spheres. One may argue whether the Vanir or the Aesir are stronger, but the wise man knows both are necessary. There are a lot of gods in Norse mythology and I’m only going to list those that cover some major D&D domain, but the rest are assumed to exist and could be worked in later.
While the Aesir and Vanir are more or less human in appearance they are still worshipped by the other non-monstrous humanoids. Gnomes and dwarves, however, are not very pious, as a rule. This may be due to their general pragmatism and focus on physical crafting. Most gnomes and dwarves show some token deference to “The Builder,” though it’s not clear to outsiders whether that’s a deity or simply an abstract concept.
