Once upon a time, in a faraway land, lay the kingdom of Hogwarts.

The kingdom consisted of four regions; Slytherin, located in the Northwest; Gryffindor, in the Northeast; Ravenclaw, in the Southwest, and Hufflepuff in the Southeast.

At the center of Hogwarts, right where the four corners of the regions border each other, stood Hogwarts Castle, where the king of all four regions resided.

Now the kings of Hogwarts were not "born to the throne." They were appointed for life by the people. The power of the king was kept in check by the Ministry, high officials selected by the people, and the power of the Ministry was kept in check by the king.

Although there were often disputes among the regions (especially Slytherin and Gryffindor) and sometimes controversy within the Ministry, Hogwarts was for the most part a wonderful kingdom , where the people lived in freedom and prosperity.

That was, until the Great War against the Dark Lord Voldemort.

The young dark lord and his followers, known as Death Eaters, had overthrown the Ministery, killed the current king and began to rule the kingdom through fear and tyranny.

But through the leadership of Count Albus Dumbledore of Gryffindor and several other brave ones, the good people from all four regions rallied together against Voldemort, and took back the kingdom.

Voldemort and his few remaining followers, barely escaping with their lives, fled the kingdom through the borders of the Forbidden Forest.

It was a hard won victory with great loss and much devastation throughout the land.

The people unanimously crowned Dumbledore as their new ruler of Hogwarts.

For nearly two decades, King Dumbledore ruled with a fair and just hand, rebuilding the kingdom and leading the people back to hope, joy and prosperity.

But evil cannot keep away forever.

It is in a humble village in Hufflepuff where we find a most unexpected hero, and our story begins...

A/N: Hi, thanks for reading. So this is sort of going to follow the plot line of "Mulan" with Harry Potter and Sherlock characters, set during Medieval times. Don't expect quick updates. I do know where I'm going with the story, its just a matter of flushing out the details.:p In the meantime, would any of you like to guess who plays which role? (Obviously, Dumbledore plays as the Emperor and Voldemort as Shan Yu.)
