(see his last post)
I see the daughter or founder of a tribe of Sun Bear hunters (a form of tropical bears) that lives in a djungle on a mountain somewhere. (Would not know where to place that in Golarion... any ideas?)
She has come to expect obedience from those around her, regardless of their station, and is not at all shy about demanding what she wants (huge intimidationi skills!)
The fluff on Reactionary I would turn around. She is a bully but she anticipates that people will try and get away, so she is very fast (initiative) to act, ideally before people know whats coming...
Maybe one could build a party of awesome Barbarians (i.e. tribesfolk, not the class) with some of the other builds mentioned. All got tribal scars of some sort...
Half-elf synthesist Summoner (see above)
Half-orc scarred witch
Dualcursed deaf-wolfscarred oralce of some kind
Half-orc scald (see way above)
Human wood Wizard
You could make a bunch of these. Get them all in one place. They are all outcasts of their own clans and gathered somewhere.
Now have PCs of higher levels stumble in on them. MUAHHAHAHA! :)
EDIT: Turns out Kellids actually seem supersticious of magic due to the worldwound being nearby, and certainly would be suspicious of one speaking Infernal! -- Maybe the worldwound could have some connection with these amazing bunch of firstlevlers... I smell potential
Witch with the slumber hex is quite powerful but I have to give it to the pet classes.
Halfing caviler for the front line and DPR. (ride by attack not SC)
Druid
Hunter
Summoner
Couldn't a human fighter with rich parent trait buy a nice combat trained mount and have the feats to get Spirited Charge?
