Dengi Marauders
Dengi Marauders (also called "Dengis", "The Wasteland Raiders" or "Skull bearers") are an ethnic group of First-wavers who originate from the Dengi valley north of The Hakusan Empire.
Dengis are a wild and primitive tribe consisting of approximately 750 adult males and females. They're known for abducting children and women that they either assimilate into their own tribe or use as breeders to water out their abnormality-afflicted genetic pool. Male raiders are also rumored to use an unprecedented savagery when defeating other warriors; chopping off limbs, eating their enemy's heart and decorating their armors with bones, ears and other body parts.
According to Thomas Eccer, The Dengi tribe originated from a group of "twelve heroes" that were thrown out from the original first-wave settlers around 2135. 300 years of isolation, inbreeding and a fight-for-survival culture have formed the almost inhuman group of people we see today.
Dengi Marauders are called "The scourge of Hakusan" for a reason, as the sword-wielding Hagui guard patrolling the north borders often come into (hostile) contact with this tribe.
Dengis south of Prometheus is thankfully a very rare phenomenon.
