The Fremen are humans who consider the planet Arrakis their home. They form an integral part in the establishment of the Atreides Empire and Muad’Dib’s Jihad launched by Paul Atreides, their adopted leader.
To the Fremen, the fight for survival has long dominated their cultural identity. The brutal environment of Arrakis necessitated the frugal use of energy and resources, especially water. Additionally, their history with cultural persecution mandated the need for combat knowledge. These two aspects saw them emerge as efficient and hardy warriors, who used their skills and the environment of Arrakis to fend off off-world opponents who often possessed far superior technology and formal training.
The Fremen make up the majority of the Jihadist’s standing fighting force, generally seen in special forces or command roles.
