We stopped by Disney Castle, but something wasn't quite right.

Heartless had appeared in the peaceful castle. We got the specifics from Queen
Minnie, then split up to get to the bottom of things.

Sora and Queen Minnie headed for the audience chamber, mowing down Heartless
along the way.

The reason for the crisis was revealed in the Hall of the Cornerstone, hidden
beneath the throne. The Cornerstone of Light that kept the castle peaceful was
being overgrown by thorns. This was Maleficent's doing!

We took Queen Minnie's advice and headed for Hollow Bastion. Merlin created a
mysterious door for us. He said we could restore the castle by closing another
door beyond this one.

We stepped into the world beyond the mysterious door, where we came face to
face with a rather nostalgic black-and-white world.

The door was connected to the past. Maleficent and Pete wanted to change the
past and make the castle their own, but we put an end to their devious plans,
and the castle was peaceful once more.
