Rossak
jungle world of the Sayyadinas
Rossak was a lush jungle world that served as a stop on the migration of the Zensunni Wanderers, and the place where an awareness-spectrum narcotic first unlocked the genetic memory of their Sayyadinas.
Rossak was a green world that became the fourth stop of the Zensunni Wanderers during their forced migration. It was on Rossak that an awareness-spectrum narcotic was discovered, a drug that released the Other Memories of the Wanderers' Sayyadinas and so left its mark on the memory of the Fremen who descended from them.

A stop on the migration#
Rossak was the fourth stop of the Zensunni Wanderers during their forced migration. It was on Rossak that they discovered an awareness-spectrum narcotic capable of releasing the Other Memories of their Sayyadinas. The Zensunni were once present on the world, but they were eventually expelled by raiders. (Dune)
Memory of Rossak#
The Lady Jessica experienced memories of Rossak when she underwent the spice agony on Arrakis. During the ceremony, in which she transformed the poison of the Water of Life, Jessica unlocked her Other Memory and recalled the original Zensunni Wanderers on the planet Poritrin, as well as Zensunni women taking the awareness-spectrum narcotics that opened genetic memory for the first time. The Fremen of Arrakis likewise recalled the raiders who pursued them on Rossak, through courtyards lush with greenery, in a ceremony led by the Sayyadina alongside the remembrance of the raids on Poritrin and Bela Tegeuse, marked by a vow never to forgive and never to forget.

Arrakis
Arrakis, known as Dune and later as Rakis, was a harsh desert world in the Canopus system and the only natural source of the spice melange. Home to the Fremen and the sandworms, it became the seat of the Atreides empire and the center of the known universe.

Bela Tegeuse
Bela Tegeuse was the fifth planet of the Kuentsing star system and reputedly the third stopping place of the Zensunni forced migration. Generations later it was conquered by the Honored Matres.

Poritrin
Poritrin was the third planet of Epsilon Alangue, held by many Zensunni Wanderers to be their planet of origin, and in the expanded universe a slave world where Zensunni captives laboured for the League of Nobles.

Fremen
The Fremen were a culture of humans descended from the Zensunni Wanderers who made the desert planet Arrakis their home. Hardened by water scarcity and generations of persecution, they became the finest fighters in the Known Universe and the foot soldiers of Paul Atreides and his jihad.
Zensunni
Zensunni was a mystical denomination of Buddislam that took root among disadvantaged and enslaved peoples across the known universe, above all the Fremen of Arrakis. Born of a schism around 1381 BG, it stressed the mystical and a reversion to the ways of the fathers, and was later steered by the Bene Gesserit.

Lady Jessica: the concubine who bore a son
The Bene Gesserit ordered Jessica to bear Duke Leto a daughter. She had Paul instead, and that single disobedience broke the breeding programme.
