I'd like to know more about this mysterious sword and why it's so important that Wahlberg's character needs to lug it around while going through the Michael Bay patented run-across-a-field-of-explosions set piece?

Raking my brain for anything and so far the only thing that relates to a sword AND the Autobot-Decepticon war is the Star Saber from Transformers: Armada.



I could be wrong though.
