All empires fall.

That's the message in the brief teaser for the fifth and final season of HBO's "Boardwalk Empire," which is very concerning for Nucky Thompson (Steve Buscemi).

There isn't much footage in the video, which is set to an ominous cover of Harry Nilsson's "One" by Alva Noto & Blixa Bargeld). We see flashes of Nucky on the boardwalk and in a boardroom, and get glimpses at Lucky Luciano, Al Capone, Nelson Van Alden, and Chalky White.

Speaking of Chalky -- his portrayer, Michael K. Williams, recently revealed that "Boardwalk Empire" will have a major time jump.

"The storyline has jumped seven years [into the future], which is why I have the beard now," Williams told Den of Geek. "The Depression has set in. The days of the shiny shoes and fancy suits are long gone."

Nucky without shiny shoes? His empire really has fallen!

"Boardwalk Empire" premieres September 2014.
