Before she entered the Games, Cathalina Ivy Sylverstar was well known by everyone in the Capitol - her whole family was known; her father, Pherydin Sylverstar, was a Victor for the Capitol and he had become a stylist to help all the tributes that were entering the Games after somebody else took over mentoring the Capitol tributes.
Winning - no, it wasn't winning, it was surviving - was hard and Pherydin knew that, so he taught his kids, Cathalina Ivy and Jerphydius all that he knew of it. They'd wake up early each morning and train. His children didn't mind, since they knew exactly why he was teaching them all of those survival skills and how to handle weapons, plus a whole lot of other things needed in the Games.
After a few years, Pherydin quit his job as a stylist and his family all moved to 5 - he was Capitol, but his wife was from 5. They loved it there; it was a quieter place to live and nobody really came up to him and giggled around him. It wasn't long after that a tragedy struck and their family fell apart. They would never be the same. Everything would go downhill after that.
