I think go to a country and take their native people as the villains is offensive. Would be nice the tribes have a role in the story, but not as the villains. Something like the draconics that help you or have some special habilityI'm not sure if this was already mentioned, but I'll say it anyways. What if the evil team is actually some sort of tribe? They're descendants from the original tribe members who worshipped said legendary, so they're trying to summon and use it to take over the region, or maybe even the entire world. Thoughts?
