You're all severely underestimating the power of technology in OR. And I don't mean shitty muskets, or even earth rifles. The genre of this setting has been Mecha for almost 1000 years in universe, and you are too blind to see it.

My greater warmachina is going to have a rotary autocannon, a blue grease based railgun, phlogiston ballast tanks, omnidirectional thrusters, fairy-guided cluster munitions, a numerology based projectile shield, a flame thrower, spiked pleb stompers, and a giant enchanted/cursed Lesser Yus chainsword for close combat.
