I've only played Pathfinder once, technically. Newest D&D I played was AD&D, but I play (and run) a lot of other tabletop games.
First Pathfinder game, didn't even finish the first area before there was too much drama. I wasn't involved except apparently as a mediator.

Also, for Scion of Humanity, could I instead take like...Scion of Elvenkind? Or something else? Since I don't want mine to be half HUMAN? Or would I have to rely on taking Racial Heritage and qualify as yet another race?
