What really intrigues me about the setting is how gods work. There's a general pantheon, but it's not divided strictly between good and evil. There's Beryls and Shajads, and while the common folk once thought Shajad were equivalent to demons, they've changed their minds in recent times.
How it works is that each god has a doctrine. One example is Uriel. He's a male Beryl that signifies freedom, and grants +1 Elan every time you set someone free.
As you amass points, you gain benefits... At the most basic level, you can access the ability 'You can always find the way out' Work on it more, and you can gain abilities like You don't stick in people's memories if you don't want, You are particularly hard to dominate, You inspire people in your proximity to seek freedom.
The most powerful ability of this guy is 'You can free those enslaved by a supernatural power'. That sounds less potent than some of the other abilities, (You gain maximum in every statistic), but you gotta figure it applies to all sorts of demons and such.
I just like it as a completely different system from spells, directly rewarding a life in your god's service. As you gain power, you generally pick up an aura that influences your surroundings; I like that for pure fluff reasons (ie. the 'Perfection' Beryl Barakiel, who is the one I mentioned that gives you 'perfect stats', makes things and people in your vicinity more organized.)
