The Terrigen War, also called the Inhuman-Mutant conflict and Metahuman War, was a major event that took place in the Earth-4141 reality. Beginning in the year 2 AT, it was a global conflict fought primarily between the Kingdom of New Attilan and the X-Army, with intervening action from both S.H.I.E.L.D. and the United Nations Security Council. This war between Inhumans and Mutants proved to be one of the most disastrous and society-altering events to occur on Earth-4141, with lingering effects that remained well beyond the conflict's conclusion.
