So how does this fit in with the Thor cosmology? Does this take place on the realms that haven't been covered in the Thor movies? Are there other inhabited planets besides the nine realms?
Are the characters aliens who happen to look like humans? Does this take place in the future? Are there humans who colonized space that we don't know about?
It ties directly to Thor cosmology in some way. If you recall, the stinger in Thor 2 had Asgardians dropping off one of the infinity "stones" with The Collector (Benicio del Toro), linking the Asgardian "nine realms" with the GotG Galaxy. The Collector is one of the villains of GotG, which means it takes place in now times and not in the 31st century. If I'm not mistaken, the nine realms are more like 9 distinct planets within the Milky Way galaxy connected by wormholes like the Rainbow Bridge. There are countless other worlds out there, just not connected by the world tree.
