Deities in the Free Cities Conclave

Gods are built, not born.

When a creature, or locations, or item becomes venerated it gains supernatural powers. This isn't the only way to wield magical power, but it is the only path to godhood.

A venerated object (or being) will start it's journey as something that its followers attribute supernatural or divine powers to. With enough belief, the effects become real, and tangible, and this will start a snowball effect, as the powers it now actually holds will inspire more faith and devotion.

I like this post by noisms over at Monsters and Manuals describing the general idea. Also this post expanding on his specific example.

Each deity will get it's own entry in time, but for now, here's a list of all of the major deities and their aspects in the Free Cities Conclave and nearby areas.

The "Invoked by" portion notes when a common person or non-worshipper might mention the deity, and is mostly included as an additional example of the feeling the God arouses in the people of the Free Cities.
