Gecko ( town ) Gecko is a ghoul town northeast of Vault City , founded in 2236 . Its economy is based on the operation of an old , half - functional Poseidon Energy nuclear power plant # 5 . Harold is the de facto mayor of Gecko , while he is assisted by Lenny , who also serves as Gecko ' s doctor . The power plant is administered by Festus . Location . Gecko can be found twenty - two squares east and two squares south of Arroyo . Background . Gecko is a place where ghouls end up , rather than a destination . Most ghouls found themselves unwelcome in human habitations . They ' ve also found comfort in the close proximity of the atomic power plant , some even living inside the reactor building to be closer to the warming fire of the atom . Gecko ' s citizens are divided between the renewal cultists and the more ordinary ghouls , who resent the cult . The renewal cultists seek to " renew , " i . e . become human again . They are headed by a giant , sentient mole rat who lives in an underground cave adjacent to the reactor , known as the Brain , who seeks to take over the world . In the short term , he seeks to build an alliance between Gecko and Vault City based on power from Gecko being sent to Vault City in exchange for medical research on how to " restore " the ghouls to humanity . The cult is symbolized by the ankh , as its members wear ankh necklaces . Interestingly , the name comes from a pre - War town in the vicinity , Gecko City , for which the nuclear power plant was supplying power . Layout . Settlement . " The Harp " is a bar tended by Wooz . It serves the usual drinks of Gecko , specialized for ghouls ' unique resistance to radiation : Gamma Gulp beer and Roentgen rum . Wooz is a rather eccentric ghoul : he tells strange stories of severed heads in hell and is obsessed with playing Tragic : the Garnering , although he isn ' t as good at it as he thinks . The " Manager ' s Office " is the seat from which Harold tries to keep Gecko together . It supplies part requisition forms and oversees reports concerning the power plant . Junkyard . The junkyard is where Gecko ' s unfinished second reactor lies , rusty and decaying for the past one hundred and sixty years . The " Survival Gear Locker " is a general store of Gecko . Percival Crump , a . k . a . Percy owns this store . He offers a decent selection of rad - resistance drugs , weapons , and ammunition . His friend , Woody has recently gone missing . Inhabiting the Poseidon Machine Shop is Skeeter , who is a “ ghoul gadgeteer ” who serves as a sort of mechanic for Gecko . He can perform weapon upgrades and , more importantly , has a fuel cell controller . However , he is considered unreliable by the ghouls who administer Gecko ' s supply locker / storage room , since he once caused a fire , and as such he is typically denied part requisition forms . He is assisted by " Lumpy " John , a human refugee from Vault City who has no visible mutations like the ghouls , but is considered unacceptably mutated by the Citizens in Vault City because of his unusual resistance to radiation . Lumpy also helps guard Gecko ' s brahmin . Gordon is a ghoul who believes that if everyone would follow their own self - interest , everyone would be better off . He proudly believes that greed is good , and wants to optimize Gecko ' s power plant and establish trade with Vault City based on their mutual self - interests . He is also a member of the renewal cult . Access tunnels . There are access tunnels under the junkyard , the underground part of the unfinished reactor and Brain ' s residence . Nuclear power plant . The nuclear power plant is the heart of Gecko ' s economy . The plant ' s supply cabinet and storage room are administered by Jeremy , the plant overall is managed by Festus , and the reactor control room is watched by Hank . Much of the installation is damaged beyond repair - the rooms are littered with destroyed terminals and damaged furniture , the control room doesn ' t have any gauges or monitors functioning and even the maintenance robot cannot run properly for longer periods of time . And then there ' s the groundwater contamination problem which affects Vault City and its inhabitants . Notes . The background music is " Industrial Junk " , which was originally used for Junktown in " Fallout " , and later in Vault 11 in " " .
