In my campaign world, I have a race of Lizardmen that worships a dragon goddess. The area they rule is about is big as the good ol US of A. The Lizardmen have domesticated dinosaurs to a certain extent but also lets them roam in the unprotected area's of their kingdom and since they are xenophobic for the most part they don't care if those dinosaurs eat non lizardmen. They have several cities but only one they allow outsiders and if an outsider is caught outside the city, they are fair game with out an escort.
The near by kingdoms knows not to F with the Lizardman Kingdom. They discovered magic before man or elf came along, they have the largest army in the world, they fight on and along side dinosaurs and their ruler is god.
What can I say. Godzilla is king! KING!
