During a four-month hiatus in the middle of '' Ghost Box '' 's publication schedule , Ellis published '' Astonishing X-Men : Ghost Boxes '' . The two-issue spin-off series featured four short stories , with each revolving around Ghost Boxes . The first story , " Agent X-13 's Report on the Emergency Annexation of Earth-616 , " is the only one of the four that does not take place in a parallel universe . Rather , it is an " alternate ending " to the '' Ghost Box '' arc where the Annexation of Earth-616 is successful . The second story , " Being an Journal By Miss Emma Frost of New Portsmouth Bay in the State of New Albion , " takes place on Earth-889 , a steampunk parallel universe . In this story the X-Men , here known as X-Society , investigate parallel events similar to what happened on Earth-616 and inadvertently cause the Hindenburg disaster . The Emma Frost of this reality would later return in the " Exalted " storyline and be featured on the team in the '' X-Treme X-Men '' title
