You once survived the explotion of a boiler in your home Skyfoundry called Vex-13. You lost your left arm and part of your beard in the explosion leading to the following:

• Your left arm is a hydraulic piston with a rotating tool socket.
  
• You “listen” to machinery and swear you hear the whisper of The Great Machina.
  
• Your beard contains at least three utility wires and a lockpick.
  
• You consider emotions less useful than torque.
  
• You once fixed a ruptured sky-engine with only a gear-cog, a fuel rag, and a half-empty flask of solderwine.
  

Brannok Rivenbraid was forged, not born. He took his first steps in the molten belly of Skyfoundry Vex-13, a clanking, drifting behemoth of rust and steam that creaked above the Edge like a dying god. His kin called him “Clank” before he could walk—after the sound his brass-plated shoulder made every time he fell onto the deckplates.

Raised in the roar of forgehammers and the hiss of pressure valves, Brannok earned his gear-arm after losing the original in the Coreback Eruption. It was an upgrade. Since then, he's collected and replaced more parts than he remembers, each bolted joint and piston-driven finger a scar and a story.

In Gearblood society, where strength is measured in solved problems and repaired engines, Brannok rose fast. He was a Forge-Captain by 20 and a living legend by 30—survivor of the Coreback Eruption, defeater of the Rustworn Leviathan, and the only engineer who dared enter the Crucible Deck without sealing the heat vents.

But his downfall came not by blade or blast, but by principle. Brannok refused to abandon a fractured foundry-node during a skyquake, choosing to stabilize it while others fled. The act saved the engines—but not his rank. Branded reckless, he left Vex-13 with nothing but his gear-axe, a ticking arm-core, and a beard full of bent memorial tags.

Now, Brannok wanders the broken skies and wreck-hulls of the Edge, seeking work, scrap, and a fight worth dying for. He listens to the ticking of his own bones and believes, like all Gearbloods, that the world is one vast broken machine. His role?
Fix it—or tear it apart trying.
