Okay some quick things about the arcane battle altars
- The spells they cast aren't standard Battle Magic, they seem stupidly more powerful than that. The Celestial Hurricanum's spell, Storm of Shemtek, summons a hurricane, drops man sized hail, or massive meteors.
- They each use a Orb of Sorcery, which means;
- Only a Patriarch can sanction their use.
For the Gold Order, the "Goldship of Chamon". Think of a Steam Tank but shaped like a ship. So what Marienburg have. The Battle Magic casted is Working of Living Metal. As this spell is cast, all metal around the Goldship gains life, writhing as if flesh. The armour of allies mends itself, and blades reform themselves to be sharper. By contrast, the enemy is attacked by their own armour and weapons, as they attempt to suffocate them, flowing into orifices. Those consumed become like metallic golems, blindly striking down their former allies.
Jade Order, I'm tempted to say it's actually a tree. Or maybe a green house on wheels. It's spell causes massive life growth, causing full forests to grow from nothing in a matter of moments. Said forests then beat the crap out of enemies.
The Amber Order's is pulled by bears/gryphons/whatever mad beast they can find.
Bright Order. Have you seen Ghost Rider? That, but it's a cart. The bound spell calls down fire from the sun itself, appearing a massive pillar of fire that annihilates everything.
The Grey Order's cart just... looks like cart. It's magic can hide an entire army from view, or summon a fog that is impossible to escape from.
The Amethyst Order's cart is probably similar to a Vampire's Black Coach, including the body of a powerful Amethyst Wizard. The bound spell is "Hand of Morr". It's similar to "Spirit Leach," but instead of slowly draining a single target the wizard can just wave their hands and whole groups turn to dust.
This is all I have, it kinda slipped away from me
