GRAVEMARK
The battle-scarred war machine

Gravemark fought the kaiju in the war that no one talks about anymore, the one that came before Ironkai ever took his post on the wall. The scars prove it: bolt-holes and claw marks scattered across armor plating that should have been replaced decades ago, but never was. Gravemark keeps them. Every mark is a kaiju he walked away from, and he has walked away from more of them than anything else standing.

He is not fast. He is not subtle. When Gravemark moves into a fight, it is because a kaiju has already broken through everything else in its way, and there is nothing left to do but end it. His fists are built for exactly one purpose, and centuries of kaiju attacks have never dulled that purpose down to anything gentler.

The younger machines keep their distance, not out of fear, but out of respect. Gravemark does not lead, does not command, does not ask to be followed. He simply shows up where the wall is breaking under a kaiju's weight, absorbs whatever it throws at him, and keeps standing when it should have been enough to put him down.
