You sighed loudly as you flopped down on your bed. Closing your eyes, you inhaled and exhaled deeply several times before opening them again and running your hands through your long, straight black hair. King Mickey had trained you for much longer and harder than usual, and you had retired worn out and exhausted.

You had been living in Disney Castle for about a year and six months, after the King had taken you in when he found yout. In that time, you had trained with the King and stayed with him. However, King Mickey had restricted you to certain parts of the castle. The only people you had ever met were King Mickey, Queen Minnie, Daisy and Donald Duck, Goofy, Chip and Dale, and the broom servants. For some reason, today's training had been intense. 'Almost as if he was testing my limits'. You smiled at this thought, thinking how you had refused to show weakness the whole time, and summoned your weapon, Broken Pieces. It was fairly similar to the keyblade Soul Eater, except it had a black and white pattern made to look like shards. Your smile was quickly replaced for a frown, however. 'Testing my limits for what?'

At that moment a servant hopped into your room, spun around twice and bowed before exiting again. This meant the King or Queen wanted to see you. Ignoring the ache you felt when you jumped of your bed, you made your way to the Castle Library.

In the Library, as you assumed, you found King Mickey waiting for you. "Ah, Maryx!" he cried as you walked up to him. "I hope I wasn't bein' too hard on ya in trainin'!"

"Not at all, Your Majesty," you smiled. "Did you want to speak to me?"

King Mickey lost his grin and it was replaced with a serious expression. "Yes I did, Maryx. Actually, I have quite a big favour to ask of ya," he added.

'A favour? He wants me to do him a favour? Why?'

The King began to pace back and forth. "It's like this, Maryx," he started. "Have I ever told ya 'bout the six keys?"

You frowned. "No, I don't think so, Your Majesty."

"Well, there are other worlds, as ya know." You nodded, wishing he would get to the point. "And ya know all there is to know 'bout Kingdom Hearts." You nodded again, ruefully recalling the hours the king made you study about Kingdom Hearts, Heartless, and Organization XIII when you weren't training. "Hidden in those worlds are six keys. When all six keys are pointed at Kingdom Hearts a keychain will be formed! This keychain must be attached to the weapon of the Princess of Darkness. When this is done, the princess's heart will glow, and the light in her heart will overcome her darkness. That light will then destroy Xemnas and all the other villains who have tried or are tryin' to use Kingdom Hearts for bad deeds, such as Maleficent! I need ya to help two good friends of mine, Sora and Riku to find the keys and accomplish this task."

"Wait, wait," you interrupted. "Why do I have to help these two? Isn't there anyone else who can do this?" You knew this sounded selfish, but you liked your life now. You didn't want anything to change.

King Mickey looked you in the eye. "No, Maryx, there is no one else who can do this." He paused for a moment before saying, "because you are the Princess of Darkness."
