Following the destruction of Kamar-Taj’s London Sanctum during the events of Rise of Apocalypse, Doctor Stephen Strange investigates a surge of multiversal rifts tied to an artifact known only as The Mask of Nyog — an ancient object rumored to predate even the Vishanti.
These rifts lead Strange to an abandoned monastery buried under the Arctic ice — once used to contain interdimensional knowledge too dangerous for mortal minds. But it’s already too late.
The mask has been activated — and its whispers are reaching across dimensions.
Strange must face versions of himself, time loops that never end, and a manipulative, banished sorceress who wants to return from beyond the veil: Morgan le Fay.
