Mercenaries of Svith
With the cleric of the mists concept, this religion is interested in water, not light. After all, living beings are mostly water, die if they don’t have water, and die if you take water out of them (as blood or otherwise). I think this is supposed to tie into the cloudiness of most of the world: means the world is very alive. For flavor in how the cleric powers play out, think waterbender from Avatar. So a hold person would be condensing water vapor into ice around them, or a harm would be like bloodbending.
