Willem Clark Dr . Willem Clark is the leader of the ghoul s at the Reservation in 2253 . Background . What is a " savior ? " The dictionary tells us it ' s " a person who rescues another from harm , danger , or loss . " But this is a cold , heartless description . What Dr . Willem Clark has done for his ghoul s at the Reservation is at least as Christ - like as another savior , at least that is what Willem would have his followers believe . Dr . Willem Clark was a gifted nuclear physicist in his human days before the Great War . He worked at the Reservation as chief scientist in the nuclear research and development department on Sub - Level 3 . Even then he commanded a loyal following of fellow scientists who were in awe of his scientific capabilities and his ability to bring out the best in his colleagues . So , when the bombs fell and everyone was too scared to move , Willem took charge and kept the survivors alive ; alive with hope that one day they would all return to the surface and start life anew . Unfortunately , not everyone made it to that fateful day of returning to the surface . Ten years passed since the bombs dropped when the survivors in the sub - levels decided to come to the surface . They were little more than two - dozen survivors out of nearly one - thousand stationed at the Reservation . But how lucky were they to survive as ghouls ? Once on the surface , a dozen ghouls , including Dr . Clark , set out into the wastes to find other survivors like them , or at least similar . The thinking at the time was that all survivors would probably be ghouls , and it would be wise to organize as many as possible into one central location so rebuilding could start . Days , turned into months , and the months turned into a year . After a year of not hearing anything , the remaining ghouls at the Reservation started to give up hope that any of the original twelve would ever come back . But one did . Dr . Willem Clark not only came back , but he came back with two , possibly three dozen ghouls in tow . When he settled back into the Reservation , he told the others about the prejudice and mistreatment ghouls faced at the hands of smooth skin humans . He then explained to the survivors at the Reservation that they were given a gift - the gift of life and the ability to adapt to this new , " Promised Earth " . It became clear to Willem that becoming a ghoul was an evolutionary process in which the ghoul body could withstand , and in fact even prosper , in this scorched , radioactive Earth . He declared that he would guide his fellow ghouls into the next age of man - the age of ghouls . The " Children of the Wastes " would inherit the Promised Earth , and Dr . Willem Clark would guide them the entire way , protecting them form the cruelty of the smooth skins , but training them for their eventual uprising against their oppressors . For nearly two centuries , Willem Clark brought ghouls from all over the wastes to the Reservation . Some stayed topside , happy to eke out an existence among the debris , while others took to the Sub - Levels of the Reservation . Those who went to the Sub - Levels enjoyed fruitful , meaningful work and much better accommodations than those who remained topside . Willem reveled in his little empire , and his ghouls began to look upon Willem as their lord and savior . They worshiped him in such a way as to deify him . Soon , Willem eventually began to think of himself as a deity , and became more reclusive over the last fifty or so years . He finally came to a point where he never left his room on Sub - Level 3 and only communicated to his fellow ghouls through computer screens placed throughout the facility . When he communicated , he would only reveal his mouth over the screen , for he felt should any of his followers look into his eyes , they would burn under his magnificence - such was his ego . When one did get the chance to speak with Willem , he would often refer to himself in the third person and put his sentences together in such a way as to sound like he was reciting scripture . Due to his high intelligence , no one was able to convince him otherwise of being a holy savior , and nobody probably could . He would continue to lead his people to the Promised Earth until his dying day , but no one knows when that will be , if ever . Appearances . Dr . Willem Clark has not appeared nor is he mentioned in any published game . He was to appear only in " Van Buren " , the canceled " Fallout 3 " by Black Isle Studios . It is not certain if he will appear in any future " Fallout " game . Behind the scenes . Clark was designed to be similar in mentality to from the 1979 movie " " .
