Sally Gold can be found in Adam Goodprice's Tattoo Parlor in the Hollowed Woods on Port Royal. Sally is a quiet lass who is also a ghost, like the other residents of the old mining town; so it's not known if she was Adam's partner or merely a customer.
NOTE
A woman named Sally Gold was once a Port Royal citizen seen around town from 2007-2009. During the Island Destructions, her poor soul was lost. Could this be her?
