these people are out to get darkseid...
for some unknown reason, darkseid has been able to acquire the wand of watoomb, the soul gem, and the terrigen mists and succesfully return to Apokolips...
Doctor Strange, Adam Warlock, and Blackbolt and the rest of the Inhumans are out to procure what is rightfully theirs...
this isnt an invasion...they merely want to get the items back and go home, though they will use necessary force if need be...
the question is, can they?
