Name: Marina Norman
Age: 28 (26 if you want to stop when she died)
Species: Ghost
Appearance: Pale skin with a few freckles and a small pair of glasses, with black hair in a long ponytail and bright green eyes. She's slim and wears a lot of blue/green/purple clothes.
Personality: She tries to act as normal as possible even when the majority of the population doesn't even know she exists. Sometimes she'll move into a new place (There's a benefit of deadness. No rent to pay!) and screw around with the ordinary inhabitants. This eventually gets boring though so she travels a lot and sometimes leaves mysterious food gifts for the living homeless.
Abilities: Interacting with physical matter, passing through matter at will, and occasionally taking in the world through the senses of a living person (although she can't control them).
Job: Eternally unemployed
Bio: She was murdered by an abusive boyfriend two years ago. He's been put away for life, of course, but she remembers nothing.
