I would suggest a Western Civilisation Defence Squad expedition, operating far away from its pristine homeland. Its mission would be to examine and catalogue specimens of surrounding races, partially to gain greater insight into their nature, but ultimately to aid in the search of the true origin of their own superior ancestors.
Party members include:
The monocled gentleman - A pure-bred scholar, acting as the leader of the expedition. Knowledgeable and polite, he will inquire about races deemed to be particularly interesting, and offer to pay bounties for skulls or even live specimens (companions, peasants and whatnot).
The radical traditionalist - Curt, abrasive and dismissive of lesser beings, this fellow is primarily concerned with mysticism and spiritual matters. He will only talk to sufficiently intelligent males, and might agree to trade mystical items. Presumably some kind of mage.
The zealous missionary - A priest of an unpopular yet still significant faith. He will gladly preach about his god, but at the first sign of counter-arguments from the player, he will become angry and condemn him to eternal damnation. He might ask for donations and provisions, but will turn hostile if the player gives him bread.
The loyal crusader - This veteran warrior is a devoted adherent of the missionary's faith. He is about as charming as your typical
Amnish soldier and is by all accounts the muscle of the operation. If engaged in dialogue, he will unleash a long stream of hostile remarks about pretty much everyone and everything he loathes in the world.
The depraved ranger - Acting as the scout and hunter of the party, this brooding northerner holds nothing but contempt for lesser (that is to say, other) races. Nevertheless, he might try to solicit charismatic and beautiful characters for unspeakable services.
The disgruntled dwarf - Pure mercenary rabble, hired as a pathfinder, labourer and supplementary guard. Characteristically greedy, this malicious little creature will eagerly reveal some party secrets in exchange for much-coveted potatoes. Information ranges from detailed accounts of the ranger taking some "less than tasteful" liberties with discarded specimens, to the location of a temple full of untold treasures (a lie, of course).
