Ezhmaar Sul Ezhmaar Sul was a male Dunmer , and one of the people directly responsible for the events of the Red Year . He is only called Ezhmaar Sul by his wife , Ilzheven , whereas everyone else calls him Sul . History . Background . Sul was the husband of Ilzheven , a female Dunmer who was selected by Vuhon , a friend of Sul , to power Vuhon ' s Ingenium . The device served to keep the Ministry of Truth aloft , after Vivec disappeared during the events of the Oblivion Crisis , and was powered by souls . Sul attempted to free his wife , but damaged it when Vuhon attempted to stop him . This caused the Ministry to resume its course and crash into Vivec City . Sul and Vuhon were propelled into Oblivion , specifically the realm of Clavicus Vile . There , they encountered a being called Umbra , who was technically part of Vile , which threw the Umbra Sword into Mundus through the rift the Ingenium created . Vuhon made a deal with Umbra for his life : in exchange , he would build a new Ingenium to allow Umbra to escape Vile ' s realm . Sul was kept prisoner and tortured for years , but was soon forgotten about . Sul escaped into Azura ' s realm , who offered him to settle problems for her in exchange of letting him go . Yet , she decided to keep him , so Sul had to escape from her as he had escaped from Vile ' s realm . Umbriel Crisis . Sul was able to escape Oblivion after decades and return to Mundus . Azura still sent him visions , though of a more helpful nature , so he could get his revenge on Vuhon . While he was sleeping in the Lank Fellow Inn in Chorrol , he received a vision of Umbriel flying over the sea . Sul realised it had to be Vuhon , but he didn ' t know where to start from . He discovered a book in an otherwise empty shelf : The Most Current and High Adventures of Prince Attrebus . Sul eventually found Attrebus . He was being held captive by some criminals , so he killed them and saved Attrebus . Attrebus thought he had been sent by his father , but Sul told him he had saved him because they both wanted to find the flying city . They needed to beat Umbriel to Vivec City , a sword named Umbra was the only artifact capable of stopping Vuhon . They headed to Rimmen . In their way to Elsweyr , they came across the F ' aashe clan . Lesspa , their leader , offered them to escort them to Rimmen in exchange of buying them Moon Sugar in the city . Khajiits weren ' t allowed to buy it , and smuggling was sanctioned with death . They were forced to accept the deal . Once they arrived at Rimmen , they bought the Moon - Sugar . When they returned to the camp , they were followed by city guards . Captain Evernal intended to arrest them , but Attrebus revealed his identity . Evernal recognized the prince , and he allowed them and the F ' aashe clan go free . Lesspa and the rest of the Khajiits decided to further escort the them to Leyawiin . Attrebus and Sul couldn ' t beat up Umbriel to Vivec City by foot , so Sul bought some materials to open a portal to Oblivion in Leyawiin . Sul prepared the ritual to open the door to Oblivion , and they were teleported to Hircine ' s Hunting Grounds . They were accompanied by Lesspa and the most veteran warriors of the F ' aashe clan . Hircine and his beasts chased them while they tried to arrive at the portal that would teleport them to Vivec City . Seeing that Hircine was about to approach them , the Khajiiits sacrificed so that Attrebus and Sul could escape . As Sul expected , when they entered the portal they ended up in Vivec City . They searched for Umbra , but it wasn ' t where it was supposed to be . Ilzheven ' s ghost appeared to Sul , she told him that the sword had been taken by a Dunmer wearing a signet of a Draugr . Ilzheven asked Sul to let it be , but Sul was determined to kill Vuhon and make justice . Attrebus realised that Umbriel was approaching them from the south . Zombies poured from the water . Sul and Attrebus tried to defend , but they ended up being captured . Vuhon teleported them to Umbriel . He was surprised by Sul ' s determination . They had a conversation with Vuhon . He told them that to escape from Vile ' s realm he had had to circumscribe Umbriel against Vile . That meant they were in Oblivion , so Sul managed to free from his chains . Sul realised they couldn ' t win , so he teleported them to Malacath ' s realm . Sul had already been in Malacath ’ s realm while he tried to escape Oblivion . Malacath was angry with Sul , but Attrebus convinced him to teleport them to Solstheim , where Umbra was being kept . Malacath agreed to help them , after all , they could weaken Clavicus Vile . Attrebus and Sul arrived at a village called Sathil . They presented themselves to the lords of castle Sathil as naturalists writing a new edition for Pocket Guide to the Empire . Lord Sathil couldn ' t receive them , but her daughter Nirai offered them shelter and the resources required for their pretended investigation . Attrebus decided to investigate the castle at night on his own . As soon as he left his bedroom , he came across one of the maids , Irinja . Irinja confessed him that she knew who he was . Sul emerged from the shadows , and he would have killed Irinja if Attrebus hadn ' t gestured not to do it . The following days they had to act as naturalists . Fruth took them to Ensleth Valley . They were wrapped in an ice storm . Sul was pushed away by the storm . Hleryn Sathil showed up with some of his men . He knew they had come for Umbra , but he wanted to know who had sent them . Lord Sathil casted some sort of spell to detect whether Sul worked for Vile , but he didn ' t find anything . He allowed them to stay in his castle as long as they wished . That night Attrebus talked with Irinja , who revealed where Umbra was being held . Elhul Sathil , Lord Sathil ' s son was locked up with Umbra in the depths of the castle . Irinja lead Attrebus and Sul where Elhul was being held captive . When they arrived at the door , she told them she wouldn ' t go any further . Sul entered the darkness to retrieve Umbra while Attrebus kept the door . Sul couldn ' t defeat Elhul , who severely injured him . Sul shouted , and Attrebus ran to aid him . Attrebus fought against Elhul , Sul managed to cast a spell that dissolved Elhul . They carefully picked up the sword without touching the blade . When they came back to the gate , Nirai told them she couldn ' t risk letting them go . Sul said that he could use Umbra to be summoned to Clavicus Vile ' s realm . They were greeted by Barbas in Vile ' s realm . Attrebus convinced the Daedric Prince to send them back to the Imperial City , so that they could stop Umbriel and return Vile the power that had been stolen from him . Vile demanded a pact , he wanted Sul ' s soul , but Attrebus denied his demand , he needed them as much as they needed him . Vile sent the to his shrine in Cyrodiil . Sul hit his head and lost consciousness . Attrebus had to craft a stretcher to tow Sul . They arrived at Lake Rumare , Attrebus took a boat and rowed to the Imperial City . When they arrived at the other shore , they were captured by undead . The zombies brought them to Hierem ' s men . When they woke up , they was locked in Hierem ' s chambers . Hierem revealed he was in league with Vuhon . After the conversation , he teleported himself to Umbriel to finalize the preparations for the assault on the Imperial City . Hierem interrogated Attrebus to learn why Vuhon was so concerned about them . He could make Attrebus weep in ecstasy . If Attrebus answered , he rewarded him with that sentation . Attrebus had to resist not to answer , but he revealed that Vuhon was afraid of the sword . Attrebus fainted , and Sul ended up answering for him to save his life . Hierem told him that he would allow them to take the sword and go to Umbriel if thing didn ' t turn out as he expected . Colin and Arese had discovered that Prince Attrebus was being held captive in Hierem ' s chambers , so they headed to save him . Colin opened the cells where Sul and the prince were captured . They designed a plan , Attrebus and Sul took Umbra and located near the sigil where Hierem teleported to Umbriel in order to teleport when he came back . Colin and Arese would wait for him to kill him . When Hierem finally came back , they were teleported just in front of Vuhon . Sul wielded Umbra , but he couldn ' t damage Vuhon . Attrebus managed to make a cut in Vuhon ' s artery , Annaïg had synthesized a venom that killed the trees from Umbriel and weakened Vuhon . Everything around him seemed to shatter and Attrebus and him started falling . They fell in the skraw caves , Attrebus called Annaïg through Coo , who told them to wait for her there . Glim found them and brought them to Annaïg ' s presence . Vuhon had discovered that Annaïg was the responsible for poisoning him , so he went to her for the antidote . When Attrebus , Sul and Glim arrived , Vuhon was already there . Annaïg revealed them that they could damage Vuhon because Umbra ' s souls was in the Ingenium . Glim guided them to the sump and he dived to the bottom . Sul had fainted because of the pressure , so Attrebus picked Umbra and he stabbed it into the light . They fell into the room where the Ingenium was stored , Umbra had fallen from Attrebus hand . Vuhon tried to take the sword , but Attrebus was faster and he stabbed the Ingenium . Vuhon shaked , and Umbra took possession of his body . Umbra offered Sul inmense power , but all Sul wanted was to end up with everything . Umbra tried to strangulate him , but after a moment , the sword finished destroying the ingenium and Umbra was expelled from Vuhon ' s body into the blade . Attrebus was possessed by Vile , who stabbed Sul . Sul grabbed the hilt of Umbra and pulled himself up the blade , and with everything left in him he struck Attrebus in the jaw . Vile was expelled from Attrebus body , but a dying Sul and Umbra melt together into a dark smoke with a heart of lightning .
