House of M is an eight-issue comic book limited series and crossover storyline published by Marvel Comics in 2005. Written by Brian Michael Bendis and illustrated by Olivier Coipel, its first issue debuted in June 2005 as a follow-up to the events of the "Planet X" and "Avengers Disassembled" storylines, in which the mutant superhero Scarlet Witch suffered a mental breakdown and tried to alter the fabric of reality to recreate her lost children. Scarlet Witch's father, Magneto, and her twin brother, Quicksilver, played major roles in the series. Like The Age of Apocalypse, the House of M replaced the Earth-616 as the main reality for a brief time until Wanda switched the House of M back to normal. It was later retconned as having occurred on Earth-58163.
