Synopsis of House of X vol 3: Once More unto the Breach
Cyclops tells Magneto and Professor X that he has gathered a team to attack the Mother Mold, a facility orbiting the sun. Cyclops and his team leave the Summer House behind.
Sabretooth is being trialed in prison designed for mutants, known as Project Achilles. Emma Frost suddenly arrives to provide to the judge a pardon from the United States government. Sabretooth walks away as free mutant and goes to Krakoa, accompanied by Emma Frost.
X-Men are approaching the Orchis Forge, the place where Mother Mold is being built, with the goal of accessing the controls of the space station, so they can send it towards the sun.
The X-Men are now docked on the station and drilling the space station, forcing their way inside. In an act of desperation, the chief of security of the space station activates a bomb, resulting in his suicide and the destruction of the X-Men’s vessel.
