Thus far the Marvel Cinematic Universe has been thoroughly Earth-bound. Then the Chitauri leapt across the cosmos to do battle with the Avengers and audiences were rocketed into the stratosphere with Guardians Of The Galaxy, but like how the more grounded films mostly focussed on American cities, Guardians was centred on one particular bit of the galaxy. The slightly grubby, very Star Wars-like bit of the galaxy. The part that the Ihumans occupy is very, very different. The Inhumans are, basically, the mutants before the X-Men hit the scene - and also, in space. The story goes that eons ago the Kree empire (who factored a little into Guardians) experimented on cave men, made them superhuman, and secluded them from the rest of humanity on the island nation Attilan. They've since moved to the Andes, Himalayas, the Blue Area on the Moon, and the homeworld of the alien Kree, Hala.
