Fenric Fenric , also known as Hastur the Unspeakable , Aboo - Fenrán , the Wolf and the Hunger , was an immensely powerful sentient force that was at least as old as the universe itself and an intelligence of pure evil , later identified as a Great Old One . Nature and powers . Fenric did have a body , one with a thousand limbs that stretched across several dimension s , ( AUDIO : " Gods and Monsters " ) but like many Old Ones lost it and became dependent on possessing others . He could presumably inhabit any body in any time , possibly killing the original consciousness if suppressed long enough . ( AUDIO : " Black and White " ) If a body became too weak , he would transfer into another . He was able to teleport and could cause lightning strikes . While imprisoned , he was still aware of events outside the Shadow Dimensions and could move people through time and space in time storm s , whilst also influencing their destinies without them knowing . These individuals , who had been touched by the curse of Fenric , were known as the Wolves of Fenric . ( TV : " The Curse of Fenric " ) He was able to control an army of Haemovore s , though this was a drain on his mind , and he was able to bestow free will onto individual creatures . ( AUDIO : " Gods and Monsters " ) Relationship with other Old Ones . Fenric was seen as being too dangerous , even for the Elder God s who were capable of dying despite their great power . As Weyland ' s shield gave the wearer the ability to destroy matter and change reality , Fenric sought it while the other Gods supported Weyland in his game against Fenric , with the shield as the prize . He was infuriated when he learned of the conspiracy against him . ( AUDIO : " Gods and Monsters " ) History . Origins . The being later known as Fenric was one of two forces , one good , one evil , which were present at the Dawn of Time and became caught in it . Somehow , the evil force survived . ( TV : " The Curse of Fenric " ) Some sources state that Fenric originated not in the beginnings of this universe but , like the other Old One s , in a universe before this one . These accounts state that Fenric bore the name of Hastur the Unspeakable . ( PROSE : " All - Consuming Fire " ) The name Fenric came from a mythic figure in Norse mythology . The myths described a monstrous wolf which would , during the final battle between gods and beasts , destroy the world at the end of time . ( TV : " The Curse of Fenric " ) Entrapment of Fenric . Prior to his seventh incarnation , as the Sixth Doctor remembered playing chess against a " shard of evil " , ( PROSE : " The Quantum Archangel " ) the Doctor ' s first known encounter with Fenric was in Constantinople in the middle of the 3rd century . Fenric ( then known as Aboo - Fenrán ) had been terrorising the area , when the prince El - Amjad tried to force him to leave . Fenric agreed , provided the prince gave him the first thing he named when he returned to his castle . El - Amjad agreed to this , but when the first thing El - Amjad named was his youngest daughter ( due to the meddling of Fenric ) , he instead sent a chest of gold . When Fenric learned that El - Amjad would not give up his daughter , he continued to ravage the countryside . Eventually , the Doctor arrived in the city , and agreed to help in exchange for freeing a slave called Zeleekhà . The Doctor went out to Fenric and challenged him to a game of chess . After 40 days of stalemates , the Doctor was able to convince Fenric that with one move , he would win . Fenric spent another 40 days trying to figure out what this one move was , growing weaker all the time . Eventually , he became so weak that the Doctor was able to trap Fenric in a flask and banish him to the Shadow Dimensions . ( PROSE : " The Curse of Fenric " ) Imprisonment . At some stage of Fenric ' s imprisonment , it briefly met and played a game of chess with the Celestial Toymaker . The Toymaker wished to claim Fenric as his new toy , while Fenric wished to take possession of the Toymaker ' s body so he could escape his prison . However , the game ended in a stalemate , and the Toymaker departed , leaving Fenric trapped . ( PROSE : " Games " ) Fenric ' s stratagem . Fenric ' s power was such that his influence still continued to pervade space and time . He set into motion events that would ensure his escape . Fenric summoned the Ancient One , the last Haemovore , from the future . When Viking s stole the flask containing Fenric sometime after the 10th century , the Haemovore followed them and the flask to Northumbria and Maiden ' s Point . Fearing its evil influence , the Vikings buried the flask beneath St . Jude ' s Church , leaving a runic inscription warning that the flask was cursed . The Haemovore remained beneath the waters of Maiden ' s Bay , gradually recruiting new members . The Haemovores , also known as the Wolves of Fenric , awaited their master ' s release . ( TV : " The Curse of Fenric " ) Still imprisoned , Fenric continued to manipulate the timeline in ways that would ensure his release . As she conducted a black magic ritual , Fenric used a time storm to whisk Lady Peinforte from her native time period of 1638 to 1988 to retrieve the Nemesis statue . ( TV : " Silver Nemesis " ) He also transported Ace to Iceworld by time storm so that she could meet the Doctor and joined him on his travels . ( TV : " Dragonfire " ) As Ace bore the " curse " , Fenric hoped that he could use Ace as a weapon against the Doctor . ( TV : " The Curse of Fenric " ) Escape and defeat . In 1943 , Maiden ' s Point served as a the location of a military base housing the ULTIMA , an early computer designed to decypher German code . The ULTIMA also had the secret purpose of translating the runic descriptions and so freeing Fenric . Once released , he occupied the body of Doctor Judson and had the Haemovores , already killing every human they could find , summon the Ancient One from his dormant state . Fenric later possessed Soviet Captain Sorin . The Doctor attempted to trap Fenric once again using a game of chess , as before , but having taken over Sorin ' s body , Fenric had learned the solution to the chess puzzle . Fenric was finally defeated when the Ancient One turned on him , destroying Sorin ' s body and leaving Fenric without a corporeal host . ( TV : " The Curse of Fenric " ) Triumphant return . He was returned to the " outer darkness " for a couple of years when he began playing a game against another Elder God called Weyland for control of Weyland ' s shield , an artefact which could grant omnipotence to an Elder God . As a response to this , Weyland had started to use the Doctor , Ace and Hex as pawns to track down and deliver him the shield . When Fenric became aware of this , he began tailing the TARDIS crew unbeknownst to them . ( AUDIO : " Gods and Monsters " ) However , Fenric had unintentionally made his presence known to the Doctor when he left a chess set in a Swiss sanatorium where the Doctor was battling the Celestial Toymaker . ( AUDIO : " The Magic Mousetrap " ) After this discovery , the Doctor began battling the Elder Gods more frequently , in an attempt to draw more attention from them , so he could eventually discover the conspiracy that he had become involved in . He fought the Karnas ' koi with Ace and Hex in Alaska , ( AUDIO : " Lurkers at Sunlight ' s Edge " ) and he then began travelling in a Black TARDIS with Sally Morgan and Lysandra Aristedes , who helped him fight the Mi ' en Kalarash , ( AUDIO : " House of Blue Fire " ) Derleth ( AUDIO : " Project Nirvana " ) and Moloch . ( AUDIO : " Protect and Survive " ) When his activities had drawn the attention of Fenric , he stranded the Doctor in 5th century , Denmark . There , he temporarily inhabited the body of a local Norse warrior travelling with Beowulf , and transported the Doctor to another dimension . However , what Fenric didn ' t anticipate was the Doctor providing his companions with the necessary information to rescue him , and giving them Weyland ' s shield . ( AUDIO : " Black and White " ) Using the shield guided the TARDIS crew to the pocket dimension that the Doctor had been transported to , and where they discovered that they had been pawns used by Weyland to further his masterplan . Fenric had taken the body of a Scandinavian warrior living in the 9th century , and discovered that Weyland constructed his shield at the behest of the other Elder Gods , who saw Fenric as an uncontrollable element , and attempted to manipulate him to his destruction by leading him on a quest for Weyland ' s shield , an artefact that would inevitably destroy him . Weyland then tried to get his pawn , Hex , to use the shield to destroy Fenric , but his plan backfired when Hex regained control and used the shield on Weyland . After the game was finished , the pocket dimension began to collapse and Fenric possessed Hex . But Hex sacrificed himself to prevent Fenric from permanently taking control and gaining power , saving the Doctor , Ace , Sally and Lysandra . When Fenric ' s corporeal form was destroyed by the collapsing dimension , he was left as a disembodied entity , alongside Weyland and Hex . ( AUDIO : " Gods and Monsters " ) Legacy . Fenric was a part of one Gallifreyan prediction of the final apocolypse , where the Timewyrm would devour Rassilon when Fenric slipped its chains . ( PROSE : " " ) On personal terms , their encounter with Fenric left an impression on the Doctor and Ace who would continue to think about it in their travels , Ace particularly remembering her experience in the time storm .
