Aria Sigil

She was born on a tiny rock of a planet - an overgrown transmission station turned metro-world.
Though the metro was fully digitized, it was quite old, and she quickly learned how to access and control the bones of the city.
She lived a long time as a thief, entertaining herself with the endless “puzzles” presented by ever-advancing security systems, before a failed job brought on too much heat and she fled to a new life as an interplanetary mercenary.
