Some ideas about the Balseraphs, if the GM is interested:
The Balseraphs are a chaotic, nomadic civilization with a tendency towards evil. Their civilization is divided into six castes, or tribes,
Kinkers: The Kinkers are a group of chaotic good acrobats with a flair for dance and ropework. They construct beautiful and elaborate tents supported by massive amounts of rope and only a few support beams, and engage in impressive midair ballets that delight audiences. Of course, those who stay after the show might very well be invited to learn some other interesting uses for knots... Most Kinkers are either elves or half elves, although they have many races in their ranks.
Lunarians: The Lunarians are a chaotic evil embodiment of barely controlled libido. Dangerously sexually open even by Balseraph standards, Lunarians routinely engage in and even celebrate incest and various forms of experimental bestiality, in honor of their goddess Lunis. In spite of their horrid deviancy, people still come to their freak shows and consult their oracles, drawn by a morbid curiosity. Nearly any conceivable race or combination of races can be found represented in the Lunarians, though more than half of them are still human. At least on the outside.
Maniacs: To the maniacs, humour is the greatest thing in the world, greater than anything else. At their core, the chaotic neutral maniacs believe that the gods of goodness have forsaken man, and given him the ability to laugh as his only tool to repel the darkness within and without. Maniacs often wear strange face paint, brightly colored wigs, and large, silly hats. Though local religious leaders do not welcome their philosophical views (which creep into their humour) their cultural practices greatly amuse people, who keep welcoming them. Most maniacs are human, but there are a significant number of orcs and half orcs among them.
Meloncholio: The Maniacs claim that the Meloncholio arose from discontented maniacs, who found humor an inefficient way to distract themselves from the horror of existence. Naturally, the Meloncholio claim just the opposite. The Meloncholio are a quiet, somber people who lead lives of quiet religious contemplation, maintaining a vow of silence their entire lives. The Meloncholio wear white face paint, occasionally with stylization to indicate their mood. Like all Balseraphs, the Meloncholio hold carnivals, but their carnivals are quiet, somber affairs that local leaders often force their charges to visit, for their moral improvement. The lawful neutral Meloncholio are almost all human.
Midwayers: The Midwayers are the pentultimate gamblers and game players of the world. The Chaotic Evil Midwayers view everything in life as a game, in emulation of their goddess Kalestra. Midwayers are often dressed in vainglorious finery, often getting buttons and clasps made of gold and silver. Midwayer caravans are basically traveling casinos, and more than a few Midwayers have taken to traveling by boat, becoming a floating manifestation of vice. People are drawn into Midwayer carnivals by greed and glamour, and quite often end up losing much more than just their money. Most Midwayers are human, but there are a number of Gnomes and Trolls among them as well.
Punkushers: The Chaotic Neutral Punkushers are the driving force between Balseraph civilization, the reason why anyone even recognizes the term "Balseraph" anymore. The Punkushers are the ring leaders of the Balseraph circus, and have notable skill in getting the disparate tribes to work together. In their own caravans, Punkushers often capitalize on local holidays and festivals, rapidly constructing exhibits and shows to entertain revelers. Even if the holidays they hijack aren't meant to be celebrated in such a fashion, the Punkushers find some way to distort the celebrations. Punkushers have a highly unpredictable appearance, and an affinity for calendars. The Punkusher tribe is a mix of dwarves and humans, with a small number of goblins mixed in as well.
The six tribes of the Balseraphs meet once a year for the Balseraph circus, in which they combine their talents to put on a truly astounding spectacle. (which it is often difficult to escape without being tainted by chaos.) The city hosting the circus is chosen seemingly randomly each year, and is just as likely to be devastated by the event as it is to thrive from it. In the short term, at least, the damage will be catastrophic. Several kings have tried to destroy the Belseraphs by sacking their circus, but such attempts are often dangerously foolish, as even the Meloncholio can fight quite admirably if forced to. (One king even left his castle to greet his victorious army, only to realize he had been tricked by the Punkushers.)
