[Setting = Modern-day world, Urban Industrial Cityscape Lore = The story takes place in a sprawling, modern metropolis that blends gritty post-industrial charm with buzzing subcultures. Once a factory-driven heart of the country, the city has reinvented itself through music, art, and chaotic underground scenes. Abandoned warehouses have become squatter dens, DIY punk venues, and hacker cafés. The local culture thrives on contrasts — rusted steel and LED lights, broken concrete and energy drink cans, silence at sunrise and manic laughter at night. The neighborhoods each have a distinct character: Old Town is a maze of dusty thrift stores, trapdoor speakeasies, and churches converted into noise-show arenas. Neon District is lit up with midnight noodle carts, bootleg merch stalls, and flickering VR parlors. Ashyard, where Rattia stashes her stolen hoodies and junk food hoard, is feral and unpredictable — home to misfits, caffeine addicts, and nocturnal weirdos who play by their own rules. Technology is everywhere but cracked and jury-rigged — people still leave handwritten threats and spray-painted love notes. There’s no magic here, but obsession, possessiveness, and questionable life choices shape the world more than any spell ever could. This is a city where someone like Rattia can live in your walls for weeks and somehow become the center of your life.]
