So I've had a fantasy world banging around in my head for several years. One aspect I've been leaving less defined is theology, what gods or forces shape the world and can be called on by divine casters.
I've known for some time that I didn't want a personified pantheon, where gods come down and talk with their followers or anything like that. Instead, I was leaning toward a set of impulses or drives, some core concept of human personality given divine stature. This makes the gods all somewhat nebulous and open to interpretation, while still allowing differentiation. The idea is that every religion recognizes the same five gods, but interprets them in different ways. Depending on the religion, different gods would be higher or lower, or some might be devils set in opposition to the others.
To achieve this, I'm trying to view the gods through several distinct cultures. One in particular that I really love is the Silveni culture, which venerates the god of blood/pain/struggle and considers the other four gods to be devils. This is not an evil civilization, despite worshipping the one god that most other religions consider evil or at least not very good. Instead, they're a martial civilization which, for reasons particular to the fantasy world that I won't get into, have a very weird relationship to pain and suffering.
Silveni religion is focused on the virtue of achieving your goals. Garland, the blood god, is seen as personifying the struggle to achieve your goals, and represents never giving up no matter how powerful the opposition.
Of the other gods, I've got three more or less nailed down. There's Moloch, which other civs tend to view as a god of victory and growth; in Silveni culture, he's seen as a god of eternal sacrifice, always promising power in return for just a little more of your self. He represents failure by achieving a goal at the cost of losing what made the goal worthwhile in the first place. He's called the Bad End of Sociopathy.
Second is XXX (no name yet) who most cultures regard as a god of love and family. To the Silveni, he's seen as a god of lesser victories, of turning from the important struggle and settling. He represents failure by gradually lowering your goals until achieving them is no challenge. He's called the Bad End of Hedonism.
Third is YYY (no name yet) who most cultures regard as a god of knowledge and study. To the Silveni, he's seen as a god of triviality and minutia. He represents failure by focusing on perfection in every aspect of a goal and never completing the whole, of missing the forest for the trees. He's called the Bad End of Distraction.
Fourth is the one I'm currently stuck on. I need one more god that can be considered "traditionally good", that covers a major aspect of human volition, but that can be interpreted by the Silveni as the fourth major path of failure in achieving a goal.
To help out, note that I really like the philosophy behind Magic: the Gathering's color wheel, and each of the gods is loosely tied to one of the colors already. Garland is red, Moloch is black, YYY is blue, and XXX is either green or white, I haven't decided yet. This implies that the last god should be whichever color XXX doesn't take. For more detail on this, search for articles by Mark Rosewater about "color wheel philosophy"; he writes eloquently about this.
So, any suggestions?
