After climate demise, Earth has been partitioned into living and dead sections. These "living sections" are large, climate-controlled domes where humans who could afford it now live. People who could not, still managed to survive in the dead. In abandoned lithium mines from the last great advance of technology, the excommunicated (Excoms) persist. The living domes maintained by the last megacorporation, Argile, have now set their sights on total control of both living and dead sections of Earth. Assuming Excoms have nothing to offer them, the senior board of Argile opted for, as stated in Section 4B i2 of Argile Inc.'s quarterly report "Excom's mass displacement by quickest means necessary". This meant killing them, as astute shareholders were sure to pick up on. The quickest means necessary was found in Argile's newest crowd pleaser, their sentient synthetic bioengineered humans, AKA Ultraviolets AKA UVs. Inside the domes, UVs performed daily tasks that insiders (people who lived in domes) found tedious, such as reading. Outside the domes, UVs were programmed as lethal hunter trackers, keen on Excom blood. Initially, Excoms that lived near domes suffered immensely, as they were not prepared for such an onslaught, most living the peaceful life of an algae farmer deep in the LI mines.
Argile's malicious plan was working. They worked quickly following displacement. Swooping into cleared LI mines and refurbishing them into residences and shopping outlets for paying insiders, stuffing their coffers, as they did not have the overhead of building domes in the LI mines. News travels fast among the Excoms, and word made it to outlying settlements in time to prepare themselves for the raids. Many glorious battles were fought in the tunnels deep within the ground. Yet, it was not until an astute observation by an Excom named Jean-Claude that the the upper hand was seeded to the Excoms. Both a valiant fighter and a staunch proponent of the Canadian Tuxedo (a style nearly a century old), Jean-Claude noticed when attacking a UV, they did not notice him until he had hit them with his mighty club. Astonished by his hand-to-hand, many could not fathom what was making the UVs sitting ducks to him. It was a downright mystery until a friend of Jean-Claude finally succumbed to his pestering to try the Canadian Tuxedo, as it was the superior fighting garment. The UVs didn't see them until they were inches away. Astonished, they had cracked it. Denim. There was a bug in the UV's eye sensor that made denim invisible to them. The Excoms worked quickly to spread the news. A rally call echoed through and transceiver in any tunnel: denim for all, denim for you. Salvaged technology from days of the past, such as ancient cathode ray tube (CRT) televisions displayed the denim savior to muster morale in the war-stricken Excoms, digital cameras used to capture new denim armour styles, and speakers to play the Excom's most important war call. Punk.
