For your average Hadean, The Scraplands are as close to a dystopia as you can reach. These people don't know Below.
Centred around Old Hades and Rattown, a huge, multi-level network of tunnels (some the size of a dog, some old Tube tunnels, some old shopping areas the size of caverns) spreads out throughout the city. This is truly the end of the road. If you find yourself Below, there is quite usually no way back. A century of pollution and discarded Gens have bred and mutated down there, and a lot of sections are about as safe as diving into a pool of broken glass.
So when a toddler was found crying, wondering the corridors aimlessly, her lifespan could be measured in seconds.
The reverse turned out to be true.
A lot of the denizens of this forgotten place had cut their ties with the world above: light, innocence, beauty. The little girl (clearly a Hybrid, a product of the coupling of two Gens) reminded them they were still alive, and they were still human.
Evelynn grew up Below. She learned which tunnels led where, she was taught to read and write by insane scientists, how to fight by burned out soldiers, how to hunt by packs of cyber-rats (most likely a failed experiment), how to be stealthy by malfunctioning infiltration robots. Protected by the community who adopted her as a mascot, she thrived, eventually becoming one of the best smugglers in town. If you need to move stuff around, without the Corps or anyone else finding out, she's the person to find. She adopted one of the cyber-rats as a pet.
This one was a personal request. I made her small, elfish, and great in a scrap. I like that she will have access to a network of people that love here, and are also the lowest of the low (and therefore invisible).
