Arroyo Arroyo is a settlement located in southern Oregon and founded in 2167 by the Vault Dweller following his exile from Vault 13 by Overseer Jacoren . Originally a tribal village , after the Chosen One completed his quest and used the G . E . C . K . in 2242 , it would eventually rise in power , becoming a large city . Background . The tribe . In May 2162 , the Vault Dweller returned to Vault 13 after defeating the Master and his army , only to be exiled for fear of encouraging others to follow his example and leave the Vault . He wandered the desert , but never moved far from the mountains that shielded the Vault from the rest of the world . Upon hearing of what happened to him , a few other residents of the Vault decided to leave and join his side , following him soon afterward . The Vault Dweller eventually came into contact with the small group of dwellers . They knew little of the outside world , and would have likely died if it were not for his knowledge and experience . After this , the Vault Dweller removed his jumpsuit , never to wear it again . Two months later , The Vault Dweller headed north , to the great canyons , with a small group of Vault Dwellers and wastelander s , and founded the village of Arroyo . Slowly , he taught them what experience had taught him , and together they learned to thrive . Over time , their ragtag group turned into a minor tribe . The Vault Dweller fell in love with a member of the tribe named Pat , and they raised a family , like all of their tribespeople . The construction of Arroyo was completed on August 18 , 2167 . Early years . Initially , they would send scouts back toward the Vault , to help others who thought like themselves , but that slowly came to an end . The Vault Dweller taught the others the skills they would need to survive and grow strong : hunting , farming , and other skills to feed them ; engineering and science to build their homes ; fighting to protect what was theirs . The Vault Dweller and his wife Pat initially led the village . The tribe grew , and grew strong with their help . In 2188 , their daughter , who later became the Elder , was born . Eventually , she and their other children became the leaders of the community . Dweller ' s departure . On January 16 , 2208 , several years after Pat ' s death , the Vault Dweller wrote his memoirs and vanished soon after , presumed dead . The Vault Dweller left the jumpsuit behind , folded on the bed . Some say the Vault Dweller was taken by the sky spirits , others say that the Vault Dweller felt it was time to move on and leave the Elders to guide Arroyo to its destiny . After the One - Moon ( Month ) Cycle of mourning for the Vault Dweller ended , activity in Arroyo began to return to normal . The final training of the Vault Dweller ' s daughter for the role of Village Elder began on February 2 . She underwent a great deal of physical training and tutoring in various sciences , mathematics , and , of course , weapon skills . Two years later , she took her mystic test , a key ingredient of which is several pots worth of hallucinogenic plants from Hakunin ' s garden . She ran the gauntlet in the Temple of Trials , using her charm to pass most of the tests after her handgun jammed ( and was ruined ) on the first level . She offered numerous criticisms of the test , resulting in many revisions . Two days later , she ascended to role of Village Elder . She ruled with a steady hand , and her wisdom was greatly respected . Chosen One . The Elder ' s son , later called the " Chosen One " , was born on March 23 , 2221 . His father is not recorded in the tribal records . The reason for this is unknown , but the Elder may have simply been embarrassed . In 2241 , the worst dry season in many years caused a drought in the Northern California area , hurting crops and brahmin in Arroyo . The Elder , having read a G . E . C . K . advertisement in her father ' s old holodisks , decided that her son must be sent to find it , as it was the village ' s only hope . On July 25 , the Chosen One began his mystic test , descending into the Temple of Trials , just like his mother had many years before . Two days later , he left his home village to find the ancient device . While the Chosen One was on his quest , on July 20 , 2242 , Arroyo was attacked by Enclave soldiers in vertibirds , wearing power armor and armed with energy weapons , and the villagers were captured and brought to the oil rig . Some of them tried to resist the attackers and were killed , and Hakunin was seriously wounded . When the Chosen One returned to the village , he found it almost completely destroyed and found a dying Hakunin among the dead bodies . Now , the Chosen One had a new quest - to save his people from the hands of the Enclave . The Enclave needed the tribals for their FEV experiments . They needed two test groups : one of clean , pure humans ; and another composed of the " mutants " that lived all over the mainland , suffering radiation and FEV exposure for decades that , to the Enclave , made them unclean . The unclean sample was easily obtained by kidnapping the entire population of Arroyo . The clean group were the dwellers of Vault 13 , who were reunited with their long lost Arroyo brethren in Enclave prison cells . In Fall 2242 , the Chosen One managed to enter the Enclave using a damaged tanker and destroyed the Poseidon Energy platform , killing the President of the Enclave and severely setting back the Enclave ' s plans for world domination . The surviving people of Arroyo and Vault 13 were free . Revival . After the Enclave oil rig ' s fragmentation , the refugees of Arroyo and Vault 13 resettled , building a new community with the aid of the ' holy ' Garden of Eden Creation Kit . Finding themselves hundreds of miles from their Vault , the members of Vault 13 chose to join the villagers in establishing a new community , and their technical expertise , combined with the villagers ' survival skills , allowed the new settlement to grow and prosper . The two branches of the same bloodline were re - united , and their savior , the Chosen One , became Elder , presiding over the village for many years to come . Layout . The village of Arroyo is divided into four areas . Temple of Trials . This is the beginning area of the game . There is a clear path that leads into the Temple of Trials , but also a path leading back to the main village . It is possible to talk the way through Klint with high enough Speech and Charisma , as he is determined to make sure the entrant endures the trials of the elders . The only way to get past Klint is to defeat him in hand to hand combat . Village . The central village portion of Arroyo serves as home to most of the tribe . Hakunin ' s tent and garden - which has been infested with man - eating plants - inhabit the northwestern corner of the map , while the Village Elder ' s tent lies just south and west . And shortly south of it lies the town well , broken and dormant with the Chosen One ' s whiny nephew Feargus pouting about it a few feet away . The south - most tent belongs to none other than your old , cranky aunt Morlis , who is in possession of a piece of rather scarce flint . The large stone monument sits peaceful and quiescent immediately northeast of her tent . The wigwam residing on the east - most bounds of the map is home to Jordan , a skilled and seasoned hunter for the tribe . The rest of the homes belong to generic tribesmen and women . Hunting Grounds . The hunting grounds northwest to the village foster a steady pack of small gecko s that serve as a source of food for the tribe . Just as well , there are a few cuttings of xander root s and broc flower s growing in the alcoves formed by the abundant foliage . These can be brought to Hakunin to be synthesized into healing powder . In the northwest corner of the map , in the secluded flat where spots of radioactive waste can be found , Nagor ' s dog Smoke is trapped by a few hostile geckos lurking near the only path back to the village . Note that the geckos are not hostile , with one exception . If this gecko attacks you and any other geckos see that , the other ones will join in as well . The Canyon . This section of Arroyo is not so densely populated , as only a few vigilant tribe members keep watch over the sole passageway into the village . Mynoc , the young warrior standing immediately next to the bridge , will offer to sharpen the Chosen One ' s spear before their departure , requiring a piece of flint for the job . The bridge connecting Arroyo to the wasteland serves as a metaphorical gateway for the Chosen One . It is here that the player leaves their tribe bearing the quest to find the G . E . C . K . , and prove to be their salvation . The canyon which the rope bridge extends across bears ancestral drawings likely created by past - possibly present - tribe members upon the establishment of the village . Destroyed bridge . The Chosen One gets here with a G . E . C . K . in hand . Enclave troopers have destroyed the village and took the rest of the tribals to Enclave Oil Rig . Hakunin is still alive to tell the Chosen One what to do now . Appearances . Arroyo appears in " Fallout 2 " as a small tribal village . However , while not appearing in - game , Arroyo is also mentioned by Emily Ortal , Marcus and Klamath Bob in " " , by which time it has become a big city . Behind the scenes . The name Arroyo possibly comes from the Spanish - an " " ( literally brook in Spanish ) , also called a wash or draw , is usually a dry creek bed or gulch that temporarily fills with water after a heavy rain , or seasonally . As such , the term is similar to the word wadi . Arroyos can be natural or man - made . The term usually applies to a mountainous desert environment . In many rural communities , arroyos are the principal roads , and in many urban communities they are important multi - use trails for recreation and pedestrian and equestrian travel .
