Here is my thinking on the deities of Heartbreaker.
The world was designed by rational beings and thus behaves according to rational logic. However, as multiple beings were involved in the creation of the world what is rational and logical shifts depending on which gods have authority at that time and place. The world is currently dragging its way out of a major shift in godly authority. This is due to the god war which brought down the last great empire on the world.
Basically when you support your god it allows you to "break" the current laws of physics as you now operate, to some extent, within your gods preferred paradigm. There would need to be some touch points though, things like time and space would need to still work and the rest of the laws of physics would exist, but on a sliding scale of godly preference. There would need to be some sort of groundwork, that is agreed upon by all the creator gods.
When you are in an area where your god/pantheon does not control supplication difficulty is increased...or you take mental stress to reduce it(max you can take brings it down to baseline). Supplication has no direct skill. You must create advantages to have a bonus on the roll. Supplication advantages are ritual, cleansing, sacrifice...and need to think on this. Miracles are basically when physics goes sideways to your advantage for a scene...maybe, perhaps there are certain stunts you can only get through supplication to your deity, or deities.
The rules of gods that I have worked out.
Gods control a raw, primal, creative magic.
Gods can be born or/and made.
Gods can die(this was a surprise when they discovered this, some interaction of gods and their creation allows for this outcome).
Gods cannot unmake something gods have made.
Gods do not(or cannot) take thier gifts back.
That is what I have, so far. Now the questions I must ask. Is morality external to the gods, or created by the gods? If external, what enforces it? If the gods created it, what makes one morality better or less relative than any morality created by man? What are the ramifications of gods that work the way I ave outlined them working? I am going to keep working on this, but I would love to hear your thoughts on the answers to these or any other questions you might raise.
