The SFPD contact our heroes, requesting a consult on a case--a burning man found in the back a store. With Wolverine's help Beast procures a tissue sample--after, of course, Storm has done away with the fire; and did I mention the dead man was floating?--and studies it upon return to X-Base Alpha. This is where the science really starts, as the dead man was a mutant. Not the average mutant, however--a mutant with three sets of chromosomes and an artificial x-gene on chromosome 66, making him a triploid. As normal mutants are diploids (having two chromosome sets, the x-gene being on chromosome 23), functioning triploids are artificial mutants and never occur in nature. And so the mystery begins. Along with the dead triploid, the police have a bag containing some personal effects including a notebook. Emma Front does some quick reading to discover that the triploid had been following his killer, dubbed "Subject X". Subject X was making his way to Charparagna, the spaceship graveyard. The X-Men, sans Beast, gear up and board the new X-Plane (prompting X-Plane and X-Cave jokes from Armor) to go investigate. Using her mental abilities, Frost locates the ship in which Subject X has hidden himself. Armor promptly throws Wolverine in, as Colossus (completely absent from the title, even now) might have done. Upon quick investigation, Wolverine locates X who is attempting to repair what is later identified as a ghost box.
X's notes also referred to a place called Tian ("Heaven"),a mysterious location in China shielded by technology that renders it invisible to anything but the naked eyes. This piques Wolverine's interest and the X-Men make it their next destination, this time taking Beast with them. Upon their arrival at Tian (a series of small floating islands), they split into three groups--Cyclops and Beast, Storm and Frost, Wolverine and Armor. Several dead, but perfectly preserved, bodies are found and discovered to be the Chinese X-Men, who died after M-Day. Each team encounters (and takes down) a triploid. Quick questioning and a mental scan reveal that the triploids have one thing in common--their creator: Forge. They hurry to the hideout of Forge, somewhere in the side of a mountain, and question him. He reveals to them that he has been creating mutants (the triploids) to defend the planet from the mutants who have traveled to their dimension through ghost boxes (Subject X and another before him). The latter group of mutants were planning to annex our Earth and make it their new home--their own dimension was beginning to tear apart and decay due to the overuse of ghost boxes. After a brief struggle Forge activates the box which the intention of sending the X-Men through to defeat whomever they would encounter on the other side. Before they can be sent through, however, Agent Brand fires a two zettawat canon (two zettawats is roughly ten thousand times the power received by the Earth from the sun) at the box as the X-Men make their escape, destroying whatever was on the other end of the ghost box and (presumably) killing Forge.
Thus concludes what I feel is a strong opening arc from Warren Ellis and Simone Bianchi (although issue 30 was Bianchi's last on the title). There is a mini-series--also written by Ellis--detailing the events of Ghost Box in alternate time-lines wherein everything went wrong. That, however, is another review for another day.
"Ghost Box" represents Astonishing X-Men #25-30.
