Jentilak are builders of dolmens, which dominate their mountainside farms. These dolmens house their ancestors and protect their farms from supernatural energies. They live in matriarchal tribes where everything is held in common and children are raised communally; they are led by a council of the dolmen-builders of the tribe.

Children are taught the crafts of the tribe from a young age and choose their role by the age of 13, when they are taken under the wing of a master of their chosen role--or allowed to study independently. Gender is not important in the tribe. The only division in the tribe is between dolmen-builders and the rest of the tribe, and even then, it is based on respect and understanding rather than dominance and power. Other common crafts are metallurgists, farmers, herders, fishers, and weavers.

Courtship is casual. No one takes a long-term partner until adulthood, and even then it is considered rare to be lifelong. Jentilak reach adulthood during their last growth spurt, which comes around the age of 18. If it doesn't come naturally, it is forced through metallurgic rituals. Adulthood means becoming an independent practicioner of one's role in the tribe. This usually entails a final test, but failure only means having to try again the following year.

Every year sees nine major fesitvals for jentilak: harvest, dolmen-builders' day (new year), midwinter (when they build straw dolls and dance around the fires), midsummer (for stone-lifting and stone-throwing), the metallurgist's day (Beltane, for trading metal trinkets), and the four days of the ancestors. Every jentilak has feast days through their life: birth, role-taking, adulthood, and retirement. It is said that one day the jentilak will enter a dolmen and never return.
