This puzzle is a little broken IMHO, so, try to work with that...

Hint 1: [Spoiler]As mentioned above, the word "empire" is a clue to the first layer of this puzzle.[/Spoiler]

Hint 2: [Spoiler]Ignore anything indicating a number above 10. (This is the ~broken part.)[/Spoiler]

Hint 3: [Spoiler]The title helps with the last part -- the answer is something that doesn't fit the pattern.[/Spoiler]
