"The 30th Hunger Games were won by our own Goldie Locksley. Her parents were goldsmiths and thought it was cute to name their daughter after a fairytale character but it makes no sense, she is a brunette..."
-Maika Sheert describing Goldie in "The 66th Mentoring"
Goldie Locksley is an Other Victor, meaning that she was a Capitol model posing to be the victor that year, even though the citizens of Panem knew that the victor that won that year was a different person entirely. Her story is ended when she is said to be killed in the Victor's Purge.
She is said to offer to be a mentor, but her offer is declined when the mentor(s) from District 1 were different people.
