The knight ran up the steps in the tower. Somewhere in this tower the princess was being held prisoner. He came towards a door, he darted to the right. When it opened, an orc came out and hit him with an axe.

Blackness came over the knight.

The knight ran up the steps in the tower. Somewhere in this tower the princess was being held prisoner. He came towards a door…

This is familiar, he thought.

...he darted to the left. When it opened, an orc came out. It could not see him, because he was behind the door. After the orc passed him, he hit the orc with his sword. The knight continued up the stairs.

Another thought popped into his head: All of this has happened before and all of it will happen again.
