Last week, Marvel released a series fo new teasers featuring Captain America's shield, a handful of Marvel superheroes from across the Marvel Universe, and the title "Secret Empire."
Marvel has not yet revealed any further details about whatever story the teasers may be referring to, but it certainly seems as if they're setting up the next big event of 2017.
The event teasers seem to be referring to a long-established criminal organization called the Secret Empire. It has been some time since the Secret Empire has been a major threat in the Marvel Universe, so it will be interesting to see how they are set up for the new story.
But who is the Secret Empire?
