Steve has reigned as king for ten years, and in a few days peace will finally come to his kingdom. Representatives of the Kree Empire are soon to arrive for the negotiations that will end the war between them once and for all. Steve is looking forward to settling down, with his hand-picked Avengers at his side -- led, of course, by the masked knight Iron Man -- and also his trusted advisors, the most beloved of whom is Tony, his court magician, the most powerful mage in all the land.
But when Steve's life is endangered, Tony makes the greatest sacrifice of all to protect his king, a sacrifice far greater than his life. And when Tony disappears under mysterious circumstances, Steve learns that even his closest friends keep secrets that he could never have suspected.
