Traditional Yammanka society is organized into social groups called kafonu (singular: kafo). Each kafo is associated with a certain set of occupations that dictate what its members may do for work and who they may marry. Throughout Yamma’s millennia of conquest and empire, the Yammankalu have imposed kafo-based governance on the rest of the world. All nations on modern Duna operate based on some form of kafonu. Below you will find a brief guide to the six main kafonu in the universe of Theonite:



Also called the Kafo of Queens and Kings, the manga koronu are a class of warriors, military leaders, rulers, and politicians descended from the rulers of the First and Second Yammanka Empires. Manga koronu are considered to be best suited to positions of leadership and dominate the majority of high-ranking positions in the government and military of Yamma and many former Yammanka colonies. Manga koronu may intermarry with their own or with koronu.

Manga koro families featured in Theonite thus far include: Biida, Biraye, Kende, and Wagadu


Ruling families that are not strictly of royal Yammanka descent, but have been granted the status of manga koro by the Yammanka government. In some contexts, these families are afforded the legal and social privileges afforded to true Yammanka manga koronu, though often they are treated the same as regular koronu.

Honorary manga koro families: Kiita, Thundyil, and Zankare


Also called the Common Kafo, Quiver-bearing Kafo, or the Kafo of Farmers and Fighters, the koronu are a class of warriors, hunters, merchants, and farmers widely considered to be the default kafo of any person not tied by blood to any of the other kafonu. Koronu may be farmers, laborers, businessmen, doctors, or any profession that is not the exclusive province of another kafo, though the highest honor for a koronu is military service. Koronu may intermarry with their own or with manga koronu.

Kele koro families: Akara, Chiba, Duno, Fola, Guang, Kankan, Koma, Kwang, Magoza, Matsuda, Mizumaki, Nandiza, Oba, Sheng, Sumba, Tarore, Tau, Tsusano, Yambi, and Yukino


Also known as the Kafo of Voices, the jaseliwu are a class of historians, musicians, and storytellers, whose role it is to guard their people’s history and to advise, entertain, and educate the rest of the population. Jaseliwu may intermarry with their own or with finawu.

Jaseli families: Balasseke, Gesseke, Harper, Kuyasse, Tirama, and Wulenkaba


Also known as the Falleke’s Kafo, the finawu are class of religious teachers, historians, preachers, and musicians. An ancient offshoot of the jaseli kafo (specifically the Kuyasse family), the finawu control all temples and religious education. Finawu may intermarry with their own or with jaseliwu.

Fina families: Sekhmet


Also known as the Smith’s Kafo, the numu are a class of craftsmen, architects, and engineers. Traditionally, numuwu are associated with metal-working, though they also work in wood, ceramics, stone, and synthetic materials. Numuwu may intermarry with their own or with senkuliwu.

Numu families: Kuruma, Koumbia, Dumbaya, and Zithathwa


Also known as the Kafo of Glass, the senkuliwu are a class of craftsmen, architects, and engineers famous for their ability to produce various types of durable glass and ceramics. Originally an offshoot of the numu kafo (founded when members of the Kuruma and Koumbia families illegally intermarried with kafoless northern tribesmen), the senkuliwu gained the status of an independent kafo when their founding members discovered the secret to making near-impervious glass. Senkuliwu may intermarry with their own or with numuwu

Senkuli families: Zilazen and Ekwenzi
