He is the oldest, most skilled, and most venerated of the Immortal Weapons - veteran of multiple Tournaments of the Seven Heavenly Cities - the fabled and feared warrior nicknamed the Green Mist of Death by few who saw him and lived - and an unending mystery even to those who cultivate mystery. But as Danny Rand, the Immortal Iron Fist, soon learned, the forbidding Prince of Orphans was no more than an Earth-born man, John Aman, given great power and trained for ages countless. Yet questions remain ... what is Aman's mission on Earth? What is the nature of his incredible power? And is there anyone who can defeat his kung fu? When Iron Fist joins Aman on a life-or-death mission to fight monsters and banish ghosts, Danny may learn the answers to these questions, if he survives!
