Thanks. This doesn't really effect my idea at all, I had in my mind that the people I would create would serve the god most likely to have something against dragons and each one slain would somehow help the town, either by a magical gift or just the riches or both. Maybe the dragons' magical power, or a portion of it is given to the slayer? Now that I've written it out sounds a bit too Skyrim. Of course it wouldn't be as common as dragon killing in that but if someone managed it they could possibly be the most powerful of the age.

Well I don't see the gods as being that directly involved and/or concerned with the dragons. They created all life.
But, if your people believed that slaying them is what a/the gods want then that's realistic, People make all kinds of interpretations out of myths and scripture and live their life based on it. 
More realistically, that dragon would have gold. Enough gold to have a night with every elven whore from Oiyaer to Bolecawn.
