Spoilers ahead for Civil War II.
Marvel has announced a new one-shot "epilogue" to this summer's event series titled Civil War II: The Oath. Revealed at the "Cup O' Joe" panel at Comic-Con International: San Diego, not much is known about the series as this point, but given the cover by Jeff Dekal it deals with the leaders of the two opposing forces of Civil War II, Captain Marvel and Iron Man.
In the story, they'll both turn to Steve Rogers for guidance in the wake of Civil War II, a mistake Spencer says will have "major consequences throughout the Marvel Universe."
Civil War II: The Oath will be illustrated by Rod Reis.
