Terrigen Mists circle the globe... but while they are the source of the Inhumans' power, they are simultaneously whittling down mutantkind's numbers and suppressing any new Mutant manifestations. Driven into a cold war, the Inhumans and Mutants know that someday, there must come a reckoning. But when a new Inhuman with the power to change the course of history emerges, there are Mutants who believe the end of their race is nigh... and are not going to take it lying down.
