Drwggwerin live in small bands in the darkest parts of forests. Each band is led by an alpha (yn gyntaf), usually a male but not always, who dominates the band through cruelty. The band is split between hunters, raiders, and slaves. The hunters and raiders serve the yn gyntaf directly. The yn gyntaf decides to whom each slave belongs when they are captured (slaves can be other drwggwerin or victims of other nations). Slaves take care of all the domestic labor, raising children, and even administrative tasks. The hunters spend most of their time tracking beasts for food (animal souls are not as nourishing as mortal lives, but they suffice). The raiders spend their time in combat, fighting and robbing and taking slaves. The yn gyntaf is the most brutal raider or hunter.

Courtship among drwggwerin is rarely romantic; because affection is considered a sign of weakness, even those who care for each other hide it and engage in brutality instead. Partnerships rarely last beyond a few weeks and are often combative. Any children are raised by slaves. From a young age, they begin training in violence. By age of 14, they are left to take care of themselves, fighting for food and a place in the band. Only the strongest survive. The death rate of children is very high; though they will not die of old age, they often die of violence or starvation.

The drwggwerin have very few customs outside of violence and their demonic religion. They sometimes feast after a good hunt or are forced to honor the yn gyntaf. Some bands create special customs of their own based around their own histories. They wear little clothing, and only ornamental clothing. They do work on special crafts, usually ornaments of bone, skin, and fur or feather. Most important to them are their weapons, usually spears, swords, and axes, crafted with fell energies.
