I have come to love some book series and ideas from some books. I like to play OCs, with hints of canons being spoken about in a past tense, usually set in a future time frame.
One I have come to love is Percy Jackson setting.
I have played in Harry Potter worlds but the setting have had a twist to them.
Marvel settings as well. I have an OC that was frozen with Captain America, she is a former German Super Soldier who changed sides.
Uhh I am willing to discuss other book series settings for one on ones, but I have been known to do them as groups as well.
