There is a quest item version for with the added ' _ oh ' to the item ID . Series . This book is part of a four - part series on the history of the Empire . Contents . The first book of this series described , in brief , the first eight Emperors of the Septim Dynasty beginning with Tiber I . The second volume described the War of the Red Diamond and the six Emperors who followed . The third volume described the troubles of the next three Emperors - the frustrated Uriel IV , the ineffectual Cephorus II , and the heroic Uriel V . On Uriel V ' s death across the sea in distant , hostile Akavir , Uriel VI was but five years old . In fact , Uriel VI was born only shortly before his father left for Akavir . Uriel V ' s only other progeny , by a morganatic alliance , were the twins Morihatha and Eloisa , who had been born a month after Uriel V left . Uriel VI was crowned in the 290th year of the Third Era . The Imperial Consort Thonica , as the boy ' s mother , was given a restricted Regency until Uriel VI reached his majority . The Elder Council retained the real power , as they had ever since the days of Katariah . The Council so enjoyed its unlimited and unrestricted freedom to promulgate laws ( and generate profits ) that Uriel VI was not given full license to rule until 307 , when he was already 22 years old . He had been slowly assuming positions of responsibility for years , but both the Council and his mother , who enjoyed even her limited Regency , were loath to hand over the reins . By the time he came to the throne , the mechanisms of government gave him little power except for that of the imperial veto . This power , however , he regularly and vigorously exercised . By 313 , Uriel VI could boast with conviction that he truly did rule Tamriel . He utilized defunct spy networks and guard units to bully and coerce the difficult members of the Elder Council . His half - sister Morihatha Septim was ( not surprisingly ) his staunchest ally , especially after her marriage to Baron Ulfe Gersen of Winterhold brought her considerable wealth and influence . As the Sage Ugaridge said , " Uriel V conquered Esroniet , but Uriel VI conquered the Elder Council . " When Uriel VI fell off a horse and could not be resuscitated by the finest Imperial healers , his beloved sister Morihatha took up the imperial tiara . At 25 years of age , she had been described by ( admittedly self - serving ) diplomats as the most beautiful creature in all of Tamriel . She was certainly well - learned , vivacious , athletic , and a well - practiced politician . She brought the Archmagister of Skyrim to the Imperial City and created the second Imperial Battlemage since the days of Tiber Septim . Morihatha finished the job her brother had begun , and made the Cyrodiil a true government under the Empress ( and later , the Emperor ) . Outside the Cyrodiil , however , the Empire had been slowly disintegrating . Open revolutions and civil wars had raged unchallenged since the days of her grandfather Cephorus II . Carefully coordinating her counterattacks , Morihatha Septim slowly claimed back her rebellious vassals , always avoiding overextending herself . Though Morihatha ' s military campaigns were remarkably successful , her deliberate pace often frustrated the Council . One Councilman , an Argonian who took the Colovian name of Thoricles Romus , furious at her refusal to send troops to his troubled Black Marsh , is commonly believed to have hired the assassins who claimed her life in 3E 339 . Romus was summarily tried and executed , though he protested his innocence to the last . Morihatha had no surviving children , and Eloisa had died of a fever four years before . Eloisa ' s 25 - year - old son Pelagius was thus crowned Pelagius Septim IV . Pelagius Septim IV continued his aunt ' s work , slowly bringing back under his wing the radical and refractory kingdoms , duchies , and baronies of the Empire . He exercised Morihatha ' s poise and circumspect pace in his endeavours - but alas , he did not attain her success . The kingdoms had been free of constraint for so long that even a benign Imperial presence was considered odious . Nevertheless , when Pelagius died after a notably stable and prosperous twenty - nine - year reign , Tamriel was closer to unity than it had been since the days of Uriel I . Our current Emperor , His Awesome and Terrible Majesty , Uriel Septim VII , son of Pelagius , has the diligence of his great - aunt Morihatha , the political skill of his great - uncle Uriel VI , and the military prowess of his great grand - uncle Uriel V . For twenty - one years he reigned and brought justice and order to Tamriel . In the year 3E389 , however , his Imperial Battlemage , Jagar Tharn , betrayed him . Uriel VII was imprisoned in a dimension of Tharn ' s creation , and Tharn used his sorcery of illusion to assume the Emperor ' s aspect . For the next ten years , Tharn abused imperial privilege but did not continue Uriel VII ' s schedule of reconquest . It is not yet entirely known what Tharn ' s goals and personal accomplishments were during the ten years he masqueraded as his liege lord . In 3E399 , an enigmatic Champion defeated the Battlemage in the dungeons of the Imperial Palace and freed Uriel VII from his other - dimensional jail . Since his emancipation , Uriel Septim VII has worked diligently to renew the battles that would reunite Tamriel . Tharn ' s interference broke the momentum , it is true - - but the years since then have proven that there is hope of the Golden Age of Tiber Septim ' s rule glorifying Tamriel once again .
