Daughters of Hecate < section begin = " CXPortalFeaturedArticle " / > The most powerful tribals in the American Southwest are the feared Daughters of Hecate and their slave tribe , the Vipers . Led by an aging , possibly insane woman of fearsome presence , the masked Daughters of Hecate collect tribute from almost all other tribes in the regions they control . Failure to obey the mandates of Hecate often results in crop failure , poor hunting , disease , and barren wombs . The Daughters of Hecate reserve a special hatred for Caesar ' s Legion because the Legion rose to power during the time of the Twisted Hair ; a tribe that regularly raided other tribes for supplies and slaves . The Legion taught the other tribes to fight back and soon the Twisted Hair tribe fled . The Legion then set upon the Twisted Hair tribe , almost utterly destroying it apart from one woman , who managed to escape ; in time , she became the Goddess Hecate , eponymous leader of the Daughters of Hecate . The Hounds of Hecate are a tribe of males who serve the all - female Daughters of Hecate . The Vipers are feared warriors , mostly feared for their uncommonly excellent health and large numbers . The Vipers often travel with Daughters of Hecate , protecting them from outsiders or foolish tribes who choose to stand up to Hecate . < section end = " CXPortalFeaturedArticle " / > The " Iron Lines " resist the Daughters of Hecate and have remained largely immune to the plagues that haunt other tribes who go against Hecate ’ s wishes . However , the Vipers never pass up an opportunity to butcher any Iron Lines they discover . Origins . After Hecate braided her hair in the fashion of her lost tribe , painted her face so that none could recognize her , and then left the Nursery . She traveled to the very same tribes that had rejected her and aided them with her new found knowledge of midwifery and herbal medicine . Once she gained the trust of a tribe , she began to preach her life / death / rebirth religion . She asked that young women of the tribe join her and aid her in helping all the tribes of the wasteland . Thus the Daughters of Hecate were born . Eventually the Daughters began to decide who could marry and who could not , who could have children and who could not . Only a Daughter was allowed to deliver a child into the world and it was done in a birthing tent set apart from the rest of the tribe . No males were allowed in or near the tent . Anyone who disobeyed their edict was either stricken with impotence or their wives bore sickly children . If a Daughter was ever harmed or killed the , men of the tribe were rendered impotent until a new Daughter was assigned to them . And so the Daughters grew in power and infamy . Unbeknown to the tribes , the Daughters were taking the best of their children and replacing them with the weak or infirm . The best of the males were taken to the Ouroboros to become warriors in the Hounds of Hecate . The best of the females were taken to become Daughters . Over the years Hecate watched as the tribes grew subtly weaker and her followers grew stronger and stronger . Soon , vengeance would be hers . Her plan was simple . When the tribes were weak enough , her Hounds would sweep down upon them and annihilate them from the face of the earth . The same would come to pass with Caesar and his legion . When all who had wronged her were gone , she and her people would march upon paradise and reclaim it as their just reward . Appearances . The Daughters of Hecate have not appeared nor are they mentioned in any published game . They were to appear only in " Van Buren " , the canceled " Fallout 3 " by Black Isle Studios . It is not certain if they will appear in any future " Fallout " game .
