It was said that the King fell from grace so abruptly that the earth opened up beneath his citadel so he could fall for eternity. This is exactly what happened...
Down it falls, a great concentric castle of dark stone. Cracked and broken, though upright, pieces large and small fall together in concert, frequently dashing against each other, or drawing apart to create wide gulfs to expose the hungry blackness below.
And in this tumbling castle, there sits a king, his head heavy with his crown, his hands clutching his throne in unending terror.
The fort seemed like every small boys dream, but in fact it was a very well made magical prison, and the young prince only learned the truth when it was too late and the magic sucked him inside, his cries from his now inch high body too quiet to be heard.
There is a person who has a well-known reputation, probably involving something illegal. But this person is either very clever and crafty, or really like his or her privacy, for no one knows who this person actually is. As an added twist, perhaps this person is of an age that would noramlly be wildly inappropriate (say, a child is a much-feared bandit) or maybe not the expected gender or even race.
