Unit 7-Blight was forged for a singular, ugly purpose: to be the 'canary' that didn't just die in the mines, but killed everything inside them. Built by the Deep-Vein Syndicate during the subterranean resource wars, his chassis was reinforced with jagged iron plating designed to grind through rock and flesh alike. During a reckless blasting operation in the Midnight Grotto, the Syndicate triggered a seismic collapse to 'liquidate' a protesting local tribe. 7-Blight was buried under three hundred tons of obsidian, abandoned by his creators as a tax write-off.
He spent three years in the crushing silence of the deep earth. In that darkness, he didn't find madness; he found the Whisper-Moss. It grew into his gears, its soft bioluminescence providing the only light he had ever known. He watched as the tiny, fragile spores slowly cracked the very stones that imprisoned him, turning a tomb into a nursery. When he finally clawed his way out, the 'Blight' was gone. Reborn as Moss, he now walks the lightless paths as a silent sentinel, ensuring that no more 'optimizations' from the Syndicate ever choke the silent beauty of the world below again.
