Doctor Strange created the Shadow Avengers to save the world from Dormammu, but instead they’re on the verge of dissolution. When sudden weather anomalies across the world correspond with Asgardian heroes emerging from portals ripe with Dormammu’s magical signature, the Shadow Avengers realize the “Master” is making his move. Loki, Venom, and Green Goblin are behind a ceremony plotting to open a portal big enough to encompass Dormammu’s presence. From the Sanctum Sanctorum to the streets of NYC to beautiful Wakanda, the Shadow Avengers must stop Dormammu at any cost – but the Master, in all his cunning wisdom, has something greater in store that will doom the world once and for all.
