Do we really need a history of humans? 

If this is written poorly (and accepted) it will affect many other players directly, can you bear such a task properly? Like 'Humans can only do XXX.' and screw every other thing in the process.

Well, it's humans, so I imagine it'd be the least contested issue- they're boring as fuck in the realms of this kind of fantasy. 
I don't imagine why limitations would affect anyone- the OP has at least implied things like magic exist, so I'd use common sense to leave that in to whatever degree. It's also why I put down the notice, in case anyone wanted to contribute or let me know something they wanted in a character (so go ahead if you want).
