He was Sul ' s friend until they faced in the Ministry of Truth and Sul destroyed the Ingenium . Appearance . He appeared to be a Dunmer of average size , his gray hair pulled back in a long queue . He wore a sort of loose umber robe with wide sleeves and black slippers . His eyes weren ’ t red , like a Dunmer ’ s ; the orbs where milky white and the surrounds black . Background . Vuhon ' s Ingenium needed souls to run correctly . Ezhmaar Sul ' s wife , Ilzheven , was chosen to power the Ingenium . Vuhon claimed that her souls was of an appropriate type and could fuel it for months . However , Sul thought that Ilzheven had been chosen because she loved Sul and not Vuhon . Sul tried to rescue her , but damaged the Ingenium in the process , causing the Ministry of Truth to crash into Vivec City . Afterwards , Sul and Vuhon were trapped in Oblivion , from which Vuhon managed to get out of by striking a deal with Umbra , a sentient being that split from Umbra . His life would be spared , but he would have to create a new Ingenium , which needed to be able to escape Clavicus Vile ' s realm . This new Ingenium was put to use , and allowed for their escape from the realm . It tore a piece of Oblivion out in the process , which was later called Umbriel . Vuhon made a deal with Hierem to summon Umbriel into Tamriel . Hierem performed a ritual in Lilmoth ' s Hist tree . Umbriel Crisis . Forty - three years after Vuhon disappeared into Clavicus Vile ' s realm , Umbriel managed to escape from Vile ' s realm . It appeared in the south - east of Black Marsh . Umbriel headed directly to Vivec City in order to find Umbra , the only thing that could stop Umbriel . An army of undead that followed Umbriel by land razed everything that got in Umbriel ' s path , supplying Umbriel with the souls needed . When Umbriel arrived at Vivec City , the zombies discovered Attrebus and Sul searching for Umbra . Vuhon teleported Sul and Attrebus to his presence . They had a conversation about what had happened forty - three years ago . Vuhon needed the power of the White - Gold Tower to completely break free Umbriel from Vile ' s influence . He proposed Attrebus to set him free if he convinved his father to surrender the Imperial City . Sul managed to free himself , and he attacked Vuhon . While Vuhon was distacted with Sul , Attrebus approached him from behind with Flashing unsheathed . Vuhon discovered Attrebus and the tendrils that had trapped him before became rigid again . Sul grabbed Attrebus and they escaped from Umbriel . Lord Rhel organized a tasting where the best four kitchens of Umbriel competed . The winner would prepare a meal for Lord Umbriel . After Toel ' s death , Annaïg took the lead of Lord Irrel ' s kitchen . She won the tasting , and she was promoted to chef . She prepared a meal for Lord Umbriel heavily influenced by the Dunmeri cuisine . Vuhon was very pleased by the meal . They talked about her life in Tamriel . Vuhon asked her to kill Mere - Glim , who had organized a rebellion among the skraws . Vuhon had a meeting with Hierem just before arriving at the Imperial City . When Hierem teleported back to his chambers , Attrebus and Sul were in turn teleported to Umbriel . Sul stabbed him with Umbra , but the blade didn ' t damage Vuhon . In the mean time , Annaïg had poisoned the trees from Umbriel , weakening Vuhon . Attrebus and Sul escaped from Vuhon . They meet Annaïg , who told them about the poison . Vuhon had to absorb Rhel and three other lords to keep going on in his body and find the venom ’ s mother . Mere - Glim guided Attrebus and Sul to the Ingenium , Umbriel ' s soul . Sul tried to destroy it with Umbra , but Vuhon stopped him . Umbra fell to the floor , and Attrebus jumped to catch it . Vuhon tried to stop him , but Attrebus was faster than him . Sul managed to take back the sword from Attrebus . Glim pulled Attrebus and Sul to the bottom of the sump . Sul fainted due to the pressure of the water , so Attrebus drew Umbra from the sheath on Sul ’ s back and stabbed the the door that lead to the Ingenium . Once they were inside the room where the Ingenium was stored , Vuhon tried to stop Attrebus , but he was fast enough to stab the Ingenium . Umbra ( the being ) possessed Vuhon ' s body . Umbra offered Sul power , but Sul wasn ' t interested in anything but revenge . Umbra throttled Sul , but after a time , Umbra ( the sword ) finished destroying the ingenium and Umbra was snaked back away from Vuhon ' s body into the blade . Vuhon told Attrebus that if they killed him Umbriel would fall into the Imperial City . However , Mere - Glim now had the power to remove the flying city from Tamriel . Attrebus spared Vuhon ' s life , and Umbriel travelled to the Realm of the Hist .
