I think we're better off being able to decide freely what we want to do, instead of attack first anyway and then maybe talk if things don't go as planned. And yes i want to expand and flourish, but not like that.
Adopting a specific government would almost certainly give options of its own. We're probably going to have three to four options of whatever regardless of whatever path we go, it's reducing our options in one area while expanding them in another. And anyway, it doesn't say that diplomacy is impossible. I don't even intend on us being a theocracy of flames forever, but it suits our needs for the moment and it's much better in my mind to have an awesome fire lord at the head of our people than a crusty tribal council of elders or whatever we're currently operating as.
I'd much rather have a solid, no-nonsense expansion and conquest plan than a fanatical nation. I'll say it again, my ideal is the militaristic expansion of the Roman empire.
Why are you implying that expansion under the leader would be 'nonsense'? He wants to conquer out the area around the lake and convert them to our beliefs if possible. This would establish us as more of a regional power and also assimilate a lot of the lake people under our rule, providing a good first step for the integration of our peoples. We need some base to start off of before we can even consider going further, and the Wielder is both among the most willing and capable of our agents towards that end, as he has already proven.
And if magic or "power" exists, same thing. I'd rather have a pantheon, a balanced study in all branches of "power", than, YES, FIRE!!! KILL EVERY UNBELIEVER!!! AND WATER SHAMANS ARE FIRST!!!!
Regardless of what you'd rather have, the point is that the only real magic we know of right now is fire magic and currently no other magical wielders are popping up to prove us wrong. The point is not to kill unbelievers; it is to convert them, which isn't particularly hard at the moment considering how our Wielder of Flames currently appears to be a one of a kind deal. If we were to bump into a Wielder of Water, it would become obvious that those worshippers have something going on and we could bump them up to a similar level of respect as fire; as for now, though, it's best to take advantage of the fact that our Wielder of Flame is pretty much proof of our religion. Also: anyone stupid enough to disbelieve in the fire when the prophet of its religion is casting up columns of flames probably should have been killed off anyway to avoid the chance of them contaminating our gene pool.
You also might want to check how the Fire Wielder is appearing downright tolerant among the water believers in our midst, anyway.
And regarding the shit shoveling, he's a DEVIOUS fanatic. He's biding his time. This does not make him good or lawful you know, he's just waiting for the right chance
He's had the right chance to take over for pretty much as long as he's been around! He's the physical embodiment of our religion with ridiculously amazing powers, had already been in an authority position to boot, he's a war hero and he's perfectly willing to teach people to lob around fireballs. A person of his caliber is being forced to waste his talents in shoveling shit because the council was angry about him teaching our people some fire magic! I don't know about you, but if I were one of our people, I'd support this guy over our tribal council in a rebellion, definitely. He has a good chunk of public support, and even without it there's little to stop him from just incinerating the council and keeping everyone in line with threats anyway if he were to be as 'cartoonishly evil' as you have time after time suggested him to be. Yet, he's never taken that step, or done much of anything beyond grumbling while accepting our punishments. How do you explain that?
