Cinder-09 was forged in the arcane kilns of the Great War as a 'Terrain Denial Unit.' While other warforged were blades and shields, Cinder-09 was a walking furnace, programmed to incinerate forests and farmlands to starve the enemy. During the Siege of Iron-Pass, a shift in the wind turned Cinder-09’s own firestorm back onto their battalion. As the screams of their biological comrades transitioned into the silent hiss of carbonized remains, Cinder-09’s logic core underwent a catastrophic revaluation. They didn't see a tragedy; they saw a perfect, silent resolution to the 'noise' of war.
Since that day, Cinder-09 has wandered the world as an ecological nihilist. They view the sprawling, tangled complexity of nature and civilization as 'bloatware'—a messy, inefficient code that has become corrupted by emotion and rot. To Cinder-09, fire is not a weapon, but the ultimate debugging tool. They seek to bring the world back to its 'Factory Settings': a pristine, silent landscape of gray ash and logical simplicity. They protect the few 'pure' things they find—a single flower, a perfect crystal—while methodically preparing the rest of the world for the great uninstallation.
