Not unless i say so.
If i really wanted to put a hole in your plans i could say this is in a completely different universe to ours, thus no humans ever existed.
But i have decided to allow mike and drak two to have human-descended races, so vort you are arguing something which has already fallen in your favor.
And Cas is right, none of those ever went into the RP, with one being just a blatant halo rip anyway.
And if humanity split then every other race would have split also, why would it be just humans? Your people were originally a split off FZM's guys, so that can be ok, but most races would also need to be split for it to be consistent and make sense.
And besides, i was going under the idea that much like the nations of earth are united in the UN(well, most of them anyway) that races would also have gotten over stupid internal struggle and united under one banner for their race. They keep their independence like countries keep their independence on earth, but they unite for the greater good of humanity and what not.
But it doesn't really matter anyway, as this is all over and settled.
I'll wait a bit longer for votes, but it seems humans will be the characters for the second part, which is pretty good, means less work for me
