Ink

Tracey was the best tattoo artist in the world. Nobody ever came close to her skill, and she invented all of the greatest innovations of skin art and body modification during her day.
You couldn’t tell from looking at her, though. She didn’t have anything on her skin… not a dot anywhere on her body.
She didn’t trust anyone else with her skin, and she just couldn’t turn her own needle on herself.
Piercings, though… if you could hang a stud or ring through it, she had it done.
Flying can be a problem. Trains, buses… she’s in no rush.
