A very long time ago, there weren't only silver and gold celestial spirit keys, there were black ones. The black keys held the strongest spirits, but were banned from human use by the Celestial Spirit King. The leader of these keys, however, didn't appreciate that rule at the time and left the spirit world on her own accord, ultimately leading to her banishment. This spirit's name was Lynx, otherwise known as Lucy Heartfilia.
