Imperial Planetologist,
Judge of the Change and leader of the
Fremen. Kynes' father was
Pardot Kynes, who first dreamed of transforming
Dune from arrid desert to lush paradise, a vision that passed on to his son.
While Pardot Kynes was revered by his
Fremen follower, he was nevertheless an outsider, but
Liet was half-fremen, and was accepted more openly, taking a Fremen wife.
As a youth,
Liet joined the
Renegade Earl
Dominic Vernius' band of
Spice Smugglers and visited
Salusa Secundus, the scorched prison planet and home of the
Sardaukar.
Liet Kynes's daughter,
Chani, became
Muad'Dib's
concubine and
mother of
Leto Atreidies II (the
God Emperor) and
Ghanima.
Kynes was killed by
Rabban following the
Harkonnen raid on
Arrakeen and the death of
Leto Atreides. Rabban destroyed his stillsuit and set him into the desert.
