Twin Mothers Forbidden Lands The Twin Mothers Forbidden Lands is a location in " Van Buren " , the canceled " Fallout 3 " by Black Isle Studios . This area is located at the rear of the box canyon that the Twin Mothers tribe call home . Background . The Twin Mothers know nothing about this area of the canyon . The goddess has steadfastly forbidden them to come here . Attempts were made in the past to explore the area , but in each case the explorers returned with tales of encountering the goddess and being warned away . Needless to say , these tales have curtailed curiosity over the years . The Forbidden lands leads to the entrance of Vault 29 . When a Twin Mothers native is detected , a projector near the entrance causes the goddess to ' manifest ' and warn away the trespasser . If the native persists and enters the pipe that leads to the vault , the door opens for him but quickly seals itself once he steps inside . He is then visited by the goddess again who directs him to the main computer room of the vault . There he is rendered unconscious and his short term memories erased . A robot then deposits him at the edge of the forgotten lands so that he can wander safely back to the tribe once he awakens . Layout . The canyon is divided in twain by a slow moving stream that flows to a crevice in the canyon floor . Here the water vanishes underground . At the head of the canyon is a forest of strange cacti that feed off the stream . Further on the land becomes almost swamp - like where pools of water have formed . At the rear of the canyon is the source of the stream , a crevice in the wall where the water gushes out like a fountain . Nearby is a large pipe , its diameter taller than a man . In the right hand wall of the canyon is a cave that winds its way up to the bluff above . The satellite dish is located here . Related quests . Enter Vault 29 . Entering the vault by the player can be accomplished in a couple of ways . Dressing as a Twin Mothers tribal will cause the goddess to manifest and warn the player away . If he continues down the pipe the door will then open for him but close again once he is inside . Otherwise he will have to hack the door open with science skill . Inhabitants . Scorpion ' s Bite . This Forbidden Lands are home to a raider clan known as Scorpion ' s Bite . Their leader , a man named Burk , became very curious about the tribe when he discovered the non - aggressive security robot s . He decided to befriend the tribe and learn as much as he could about them . Over the months he learned of their belief in the goddess , their pacifist ways , and that the goddess has apparently abandoned them . With this information in hand he began to demand tribute from the tribe in the form of food and livestock . He also set up camp in the forbidden lands because the natives refuse to enter them . Most of the raiders blindly follow Burk ' s orders . He is a well educated man and has proven to be quite good at what he does . His leadership has led the Scorpion ' s Bite clan to a position of dominance in the wasteland . However , there are two dissenters among his ranks , Trisha and Sharon . Trisha . Trisha is a pretty young woman who has no qualms about using sex as a means to get what she wants . She has been in several raider clans , has worked her way to the top , and then been instrumental in the clan ' s destruction . In each case she has come out on top with a position of power in the new clan . Trisha is now Burk ' s girlfriend . Currently she is trying to find a way to deliver a holo - disk to a member of Caesar ' s Legion . The disk completely details the Twin Mothers area and provides all the information necessary for a take over . Sharon . Sharon is a cruel mean spirited woman who wants nothing more than to be taken care of . Like Trisha , she has no qualms about using sex to get where she wants to be . However , unlike Trisha , Sharon is overweight and not very pretty . When Trisha came into the picture , Sharon was immediately cast aside by Burk . This train of events has not improved Sharon ' s disposition at all . She would like nothing better than to put a bullet between Trisha ' s eyes so that she can get back into Burk ' s bed and the easy life she once had . Appearances . Twin Mothers Forbidden Lands was going to appear in " Van Buren " , the canceled " Fallout 3 " by Black Isle Studios .
