Chapter 1: Once upon a time
"Can we hear it again?" A four-year-old Oswald the Rabbit asked eagerly with his five-year-old foster brother, Goofy the Dog nodding just as excited. "Please?"
Yen Sid chuckled warmly, cradling young three-year-olds, Mickey Mouse and Donald Duck in his lap. "Alright, one more time. But then you have to go to bed."
"Once upon a time, in a land where fairy tales were not just stories but also real, there stood a kingdom unlike any other, a kingdom beautiful and magical in all its glory. This kingdom was called Fantasia, for the fantastic gifts that it bestowed upon the land. It was a paradise of peace, freedom, and happiness, protected by the generous power of the Dream World.
But this joy was not to last.
From high up on the peaks of the Bald Mountain, an ancient evil emerged. A demon of Hell named… Chernabog.
With the great power at his disposal, Chernabog laid waste to the land, for he despised the people below. Nothing escaped his wrath and flames.
Nothing… until one day, four mages stood forward to oppose him. They were the four most powerful mages in all the world, able to tap into the power of the Dream World itself. And with the King of Fantasia, they battled and defeated the demon, casting him back to the heights of the Bald Mountain.
However, before he was sealed away, Chernabog swore he would one day return and bathe the world in his flames.
Despite their victory, sealing the demon away had drained the four mages and their king of much of their power. They knew that in order to protect the world, they would have to pass their powers onto someone else.
And so they set out to find the ones whom they felt were worthy of their gifts, eventually transferring their magical powers to four orphaned newborns who they saw as pure of heart and destined for greatness, while the king passed his powers down through his descendants.
While the descendants of the king would be kept safe in the castle of Fantasia, the four mages left the four orphans with their teacher, who they, along with the king, they trusted above all else.
Because they knew as long as these children were safe, there was hope. Hope for the future. Hope for the dreams."
By the time Yen Sid finished, the children were already asleep. Smiling fondly, the wizened old wizard gently placed Mickey and Donald on the bed with Oswald and Goofy, sliding the blanket over them.
As he walked out of their room, Yen Sid took one last glance at the children he had sworn to protect. One day, they would have to face their destiny. But when that happened, they would be ready.
He would make sure of it.
