Well the point wasn’t that every race has to have an enemy, but that every god might have a different preferred race. And the player doesn’t have to go with their racial god if they don’t want, but that makes the path more difficult.
God A: God of Thieves, Gnomes, and Halflings, represents dexterity and ingenuity. followers get bonus to dex, devoted followers get boost to luck.
God B: God of Machinery and Minerals, unnatural creatures. followers might get ability to assemble mechanical pet or other devices. Some dwarves follow this god
God C: Evil god 1, this god hates all living things and desires nothing more than the complete destruction of the world. Bonuses are more about annihilation and destruction.
God D: Evil god 2, this god doesn’t hate all living things, she just wants to subjugate them all to her will. Bonuses are more about breaking a opponents will and spirit, weakening their mind.
God E: God of Nature 1: Despises all things mechanical, unnatural structures, items crafted from extracted minerals. Followers heal faster when in nature. This would be the god the Elves and druids would be most inclined to follow.
God F: God of Nature 2: God of storms, grants powers to it followers for the destruction of those that would harm nature, things that are unnatural, the undead, demons, mechanical beings.
God G: God of War 1: Combat is an art, and honorable combat is preferred. Followers would not cheat or use items to give them an unfair advantage. Since it is not chivalrious to take a opponents limb, followers would be inclined to target the head or body of a target, or disarm them.
God H: God of War 2: War is hell. Fighting is something you do to survive, but it stains the soul with the blood of the fallen. This god understands your sacrifice and grants upon his followers comfort when they reflect upon their deeds, and the strength to see them thru their battles.
God I: God of war 3: Kill them all, let Belly sort them out. Abilities only work while in combat. Bonus for multiple enemies.
God J: God of Magic 1: Grants followers increased magic attack, they allow the power of this god to flow thru them into their enemies.
God K: God of Magic 2: Increases the defense of the follower against magic, a popular god among the magically declined races like the orcs and ogres. Magic is absorbed by the follower and returned to the god.
This is just off the top of my head, but you can see some of these gods are ideal based, some are more class affiliated, and others are racial. But with a few exceptions, just about anyone could follow any of them.
