Doctor Stephen Strange has been acting increasingly unstable. Haunted by visions of people he doesn’t remember — Wanda Maximoff, America Chavez, and an infinite staircase — he isolates himself inside a collapsing Sanctum Sanctorum that changes shape daily.
When reality begins melting — literally — in various cities across the world, Clea (now Sorcerer Supreme of the Dark Dimension) arrives, furious. She accuses Strange of opening something called The House of Worlds, a sentient multiversal infection created from broken timelines, forgotten people, and dead gods.
Strange insists he didn't.
Then he finds the note in his handwriting:
“DO NOT OPEN THE DOOR.”
