Leidolf: A numerous clan, traditional enemies of Nokolai, implicated in the attack on Rule’s father [Books 1, 2, 3]. Randall Frey is the Lu Nuncio (heir) in the first two books, but is killed in Book 3. The Rho in Books 1–5 is Victor Frey. Victor’s other son is Brady Gunning, a sociopath: “tall, blond, and bony; nice chest.” Their Rhej is Ella—African American, tall, broad frame, Baptist. Leidolf currently has no subordinate clans. After Book 3: Randall Frey is dead; Rule is Leidolf heir; Alex Thibodeaux (grizzled, just under six feet, built like a pro wrestler, with skin the color of burnt toast) is Lu Nuncio for the clan; and their Rho (Victor Frey) is in a coma and dying. He dies in Book 5 (Mortal Sins).
Szós: Hungarian clan that immigrated to the United States; Rikard Demeny is Lu Nuncio in Book 2. After that, Lu Nuncio is Lucas, third-born son of Rho Andor Demeny. Fierce fighters. One subordinate clan (Czech; didn’t immigrate).
Ybirra: Large Spanish clan; the newest clan, founded in 1882 by Tomás Ybirra. Javiero Mendozo is Lu Nuncio; Manuel Mendoza is Rho. Clanhome in New Mexico. One subordinate clan four years before the opening of the series.
Wythe: A midsized clan with a Clanhome in northern New York; the last clan to immigrate to the United States. Originally from England. Lu Nuncio is Brian Whitman, younger brother of the Rho Edgar Whitman. Both Edgar and Brian die in Book 8.
Canada
Etorri: A tiny clan with great du (honor, face, magic, history); Stephen Andros is Lu Nuncio. Previous Rho was William Carr; current one is Frederick Andros. Follows different rules for succession and does not accept subordinate clans. Clanhome is in eastern Canada. Etorri is said to be Greek, though the identity of its founder is one of many secrets kept by the clan. Etorri is a puzzle to the other clans.
Kyffin: The smallest dominant other than Etorri, based in western Canada; Jasper Herron, the Rho, is unusually young (forty) and a friend of Rule’s. Subordinate to Nokolai for a year and a day, starting in middle of Book 1. The Lu Nuncio is Jasper’s uncle, Myron, as Jasper’s son is too young. Kyffin’s influence is due largely to their friendly relations with pretty much every other clan.
