Raskolian Raiders

From what can be gleaned of scant records and accounts, the Raskolian Raiders were a group of nomadic warriors that arrived in the Primus Territory at some point before the settling of the Havanites over 4,000 years ago. Members of the Killian Institute at Lexington have conducted archaeological investigations at locales like the Adoban Peaks and O'Boyle Swamp, finding convincing evidence of early Raskolian activity. Early days of Havanite history show numerous clashes between their small settlements and roving Raskolian warbands. This activity reached its peak at some point around Y2100-Y2150; that is not to say that raids ceased following that period. Isolated Raskolian tribes have been found as recently as Y3562, many years after the defeat of their latest leader Magnus Gariksson. 
While the bulk of documentation describes conflicts between Havanite and Raskolian forces, very little is known about Raskolian culture and society. Due to their nomadic nature as well as their superior knowledge of stealth and enviromental navigation, very few outsiders have ever seen the grounds of a Raskolian community. It has been tentatively agreed that the average size of a Raskolian tribe numbers about 200-300. All of the tribe's men look to be fit for combat, whereas the women seemed to focus on various professions related to homesteading. There is also mounting evidence that various fauna were domesticated and used not only for societal purposes but combat as well. It has been noted that Viper Swifts, a predatory bird not indigenous to the Primus Territory, seemed to arrive around the suspected arrival time of the Raskolian Raiders and mirrored the raiders' nomadic patterns. There also a number combat accounts of large, blue humanoid beasts fighting alongside the raiders. It is not known if this is a distinct species separate from Homo Sapiens, or some sort of ritual augmentation process of a human being. 
One recorded account of a Raskolian man rejected from his tribe provides a detailed look at daily life in a Raskolian society:
"I've been stricken from my kin. I was but a whelp, surpassed by my own brother, and my dulled spear could not pierce the chest of the Blue Ogre. My mother spat in my eye, and tore my beard from my face. I wear these burns of soot in shame. They are a sign for any kin that look upon me to offer but fists and rage. I stand before you now, foul pygmies, men who scurry and hurry for any shred but a shred of honor. Do what thou wilt. Take what thou wilt. For I have nothing left to give."
