The Legacy of Secrets, or the Campaign of Darkness is the conspiracy of the Hollingsworth family to put an end the Disney Parks forever. It is the true reason that the Kingdom Keepers had been formed, to combat a human threat back in the 1950s
It all began with Amery Hollingsworth, who hated Walt Disney for apparently taking credit for creating the Evil Queen, Maleficent and the Wicked Stepmother. He did whatever he could to cripple the parks, eventually resorting to stealing the magic ink Disney owned and brought the villians to life with the goal of destroying the parks.
Amery eventually committed sucicide, but not before his son Junior was poisoned with his insaity. Junior spent years looking for a back-up plan, finding it in the Fairlies.
