Discontinued! Tower above the Tree

Long ago an enormous tree suddenly grew out of nowhere until it touched the sky. Many people wondered what to do with it, but when different people started to climb it they discovered a tower that lay on top of the tree. The tower seems to have around 100 floors, each floor contains a clue to the tree and the tower. But a century had passed and over a hundred thousand people had entered but never returned.

Through the years they discovered that a King lived at the top of the tower. No one knew who the king was but rumors spread like wildfire, that if you reached the 100th floor you would be granted anything you had ever wanted and the ability to leave and reenter the tower at will.

But it seems like someone had already made it to the top. No one knew who and what they did but the King had them promised that they can't remember so they are heading back to the top once again to seek out what it was and why they can't remember.
