The Lanzadonii were an offshoot of the Zelandonii. They were founded by Dalanar, a master flint-knapper, and his mate, Jerika. Because the Lanzadonii had only recently separated from the Zelandonii, they spoke the same language and shared the same culture. They even attended the Zelandonii Summer Meetings. At the time of Jondalar's return, some Lanzadonii were thinking about founding a Second Cave of the Lanzadonii. At that summer meeting, they hoped to recruit a young zelandoni to serve as their lanzadoni.
