Re: [interest in an online game?] Avengers: Generation 3
Okay, I got something-
The Inhuman Royal Family, since departed for Parts Unknown, womewhere in space, send back an emissary to Earth, to remind Earth's heroes of the Inuhmans, and in general, check up on their planet- make sure the Kree aren't doing more genetic experimentation, Maximus hasn't released a plague, whatever. Furthermore, if this emissary determines that Earth is safe to return to, the Inhumans may send a colony back to Attillan (wherever the writers decided it should be this time).
Since this mission is not that high a priority though, they send a young and relatively inexperienced member of the family, or one who has fallen out of favor with the Council (who would not therefore be able to summon the entire race at a moment's notice, call on them to give him technology or support- basically, make this emissary effectively stranded and cut off for some years). My character would be this emissary.
