Khans

"'The glory of the Great Khans will be restored, and once the NCR is dead, all the land from here to the Colorado will be ours.'"The Khans are a tribe of brutally vicious and semi-organized raiders with a culture based around the basic tenets of Social Darwinism. They are one of the more formidable of the four groups (Khans, Vipers, Jackals, and the community of Shady Sands) that originated in Vault 15. Most wastelanders view the Khans as the founders of the chem trade. They are also known to make jet, psycho and many other addictive chems. Their main base in 2161 was located southeast of Shady Sands. At least twice, the Khans have suffered a brutal near-defeat, but, "like a Phoenix", the group has always managed to rise again from its ashes.
