Barbarians
Barbarians come in two major tribes, the Peloki and the Malet.
The Peloki are your standard blue-painted maniacs, and are the tribe that (some) members of The Six draw followers from. They tend to be bad people, and worship either with NE druids, or worship the Devourer. Peloki don't tend to worship the Spider Queen, as they consider lies and disguise (aside from a purely military ambush) as dishonorable. Peloki who just aren't feeling the CE/NE thing tend to work in the kingdoms as scouts, hunters, and mercenaries.
Peloki survive by raising livestock, low-grade agriculture via slaves, and of course by raiding the kingdom, the Malet, and each other for supplies. The Peloki tend to range between Hadrian's Wall on the South to where Dundee is to the North, but borders to them are something that happens to other people. They are not skilled metal workers, and tend to use non-metallic weapons and armor (think Huron, pre-horse), though they will use metal weapons that they capture or steal. They fight on foot, horses are for selling or eating after being stolen. To be captured by the Peloki means slavery, until ransomed, sacrificed, or just plain worked to death. A slave has no means to better his condition except escape. The Peloki view escaped slaves as sport, and it doesn't end well.
The Peloki view the Malet in much the way they view the kingdoms: Effete subhumans who exist to be raided and enslaved. Peloki have a particular hatred of arcane spellcasters, with the exception of bards. They also include blood ragers and more than a few rangers in with the standard barbarian.
The Malet Live North of where Dundee is, to include the islands (Faeroes, Shetlands, Orkney, etc). The Mallet clan structure is far more diversified than the Peloki, with adoption into a clan possible for anyone other than a Peloki (whom they kill outright on capture). Think of them as the various Celt tribes of the UK and France. They tend to dreadlock their hair, and wear cured hide clothing.
The Malet live off of livestock, some farming, fishing, and of course raiding. Most clans do not practice slavery, but may take prisoners to be traded back to the kingdoms or adopted into the clan. Malet tend to follow N druids, or use shamans for the clan, or both. Their druids and shamans tend to get along. Some island clans worship the dark tapestry gods. Malet, especially on the islands, tend to have sorcerous bloodlines [add common bloodlines]. Some island clans worship the dark tapestry gods, and tend to behave as you'd expect. The Spider Queen is sometimes worshiped on the side, because Malet are allowed to lie to non-Malet. Malet tend to be barbarians, rangers, and the occasional fighter. Blood ragers exist, but are rare.
While not as aggressive (read: batshit insane) as the Peloki, the Malet are very territorial and don't like strangers wandering around in their clan's lands without leave. The few imperial lords that exist North of the line live in Malet territory, and are allowed local rule (and their lives) because they have a demonstrated ability to kick Peloki ass, and also because they don't mess with the traditions of their subjects. The Malet will engage in trade with the kingdoms, usually by boat.
