Crystal Tower The Crystal Tower , also known as the Crystal - Like - Law or Lawful Crystal , after its housing of the Transparent Law crystal which rests atop the tower . is an ancient tower located on the mountains of Eton Nir , in the province of the Summerset Isles . It was built by the Aldmer as a monument to the spirit of the elves , living and dead . The Crystal Tower was the pinnacle of magical education until the foundation of the Arcane University . Description . Geography . The Crystal Tower is situated on the northern end of the Isle of Summerset , overlooking the Abecean Sea and the rest of the land . The nearest settlement to the Tower is the city - state of Cloudrest . The Crystal Tower is exceptionally large with a slender build , being able to see the southern tip of the Dragon ' s Teeth Mountains in Valenwood , which extends all the way to Skyrim . The halls were reflecting white , with light radiating throughout the windows . Along the halls are fountains with water flowing through it . The Crystal Tower holds various private collections and treasury , filled with relics of the past . Around the area is large forest . History . Merethic Era . When High Lord Torinaan had arrived onto Firsthold , the Aldmer expanded their holdings and colonizing the Isle of Summerset , building small settlements throughout the landscape . The Aldmer created the Crystal Tower as a memorial to the spirit of the elven people , not the Kings and Gods , but the people . Deep within the walls the ancient remains of the original Aldmer settlers . The Crystal Tower remained , as the Aldmer villages grew into wonderous cities . As time went on , the Crystal Tower began to house records that Aldmer colonials created , including information about the creatures living on the land prior . Throughout the eras , the Crystal Tower has been held sacred to the Altmer . First Era . A Breton that was in the Crystal Tower was the Archmagister , I ' ric Harad Egun , who was well acquainted with Moraelyn of House Ra ' athim and Edward , King of Daggerfall . I ' ric knew Edward since the latter was a child , a Prince of Daggerfall , and he knew Moraelyn even more , knowing his connection with Edward . When they visited I ' ric in the Crystal Tower , Edward was presented a Mithril Staff , and Moraelyn trained Edward with his Ebony dagger called Tooth . Before this , Moraelyn was a student at the Crystal Tower , one of the very few non - Altmer students . He brought his companions along with him to learn more about Spellcasting , but unfortunately , Moraelyn was the only one allowed in the Tower . He stayed for two weeks while his friends were waiting for him in distant Firsthold . When reunited with them , he took his friend Mith to the Crystal Tower to study along with him . Second Era . Throughout the years , many notable figures have studied from the Crystal Tower , and learning from the vast archive . Hailing from the minor village of Moonguard in High Rock , Gyron Vardengroet was born with extraordinary talent in magic , more so than the average Breton . He had taken lessons from his local wizard to the Mages Guild hall in Shornhelm , where he was taught by Morkledder , the Guildmaster . Eventually , Gyron had learned all he can from Morkledder and was sent to the Crystal Tower , where he would be trained even further . At that point , he was well - known in the magic community , and when he arrived at the Crystal Tower , the mages were given him their undying attention . It was there Gyron was taught by Esthlainder , the Elder of the Council of Wizards . Finally , the Elder admitted Gyron from the Crystal Tower ; he emerged with immense and boundless knowledge . With everything he had , Gyron returned to Moonguard , where he lived out the rest of his life in a cottage , until his parents had died , from there he returned to the Crystal Tower , to learn about prolonging his life . And so he remains to this day , deep within the Kurallian Mountains of High Rock , in a magical fortress . On the Evening Star of 2E 563 , Ayrenn Arana Aldmeri was accepted to the Sapiarchs ' Labyrinth . Which is an esteemed school that was required for Ayrenn ' s ascension to the throne of Alinor and the Summerset Isles . It was there , Ayrenn was to study Altmeri Regal Praxis and Ceremoniarchy for thirty - five hundred and fifty - five , coincidentally playing into Ayrenn ' s birthdate . And so the royal family gathered at the Crystal Tower to celebrate this momentous event , but Ayrenn disappeared from the Isles , even the Thalmor Justiciers were unable to find the Princess . It was on that day , Ayrenn left the Summerset Isles , to experience the world and its people . On that day , an eaglet had landed on a statue of Topal the Pilot , prophesizing the Aldmeri Dominion . Ayrenn would return when her father , King Hidellith had passed away . Third Era . During the Imperial Simulacrum from 3E 389 to 3E 399 , Emperor Uriel Septim VII was imprisoned along with Talin Warhaft in the Deadlands by Jagar Tharn . Tharn planned for months to capture the throne , and he was able to achieve so in the span of ten years . Tharn had a powerful weapon called the Staff of Chaos , and he split it into nine pieces and scattered them across Tamriel , the staff was the only thing keeping Uriel Septim and Warhaft in Oblivion . A warrior escaped his clutches and traveled all corners of Tamriel to retrieve the missing pieces . The hero was known as the Eternal Champion , and he assembled the staff and defeated Jagar Tharn at the Imperial Palace . The Eternal Champion had at one point visited the Crystal Tower in their quest to recover the pieces . The Eternal Champion had retrieved the fourth piece of the staff from the ruins of the Halls of Colossus , continuing their quest throughout Tamriel . In their sleep , Ria Silmane came to the warrior through a dream , telling them where the next piece is , which was Crystal Tower in the Summerset Isles . The Champion had then traveled to the city - state of Lillandril , to get an idea on the Crystal Tower ' s location , and was directed to Corim Ashlen , the Loremaster of the Mages Guild . Before they were given the whereabouts of the Crystal Tower , the mage gave the Champion a proposition , if they defeated the priests from the Temple of the Mad God ; then he will give them what they need . And so , the Champion was able to get the coordinates for the Crystal Tower and retrieve the fifth piece of the Staff of Chaos . The Champion would then set their sites for the province of High Rock . During the waning years of the third era , the youthful Altmer took a critical view of the High Elves ' xenophobia and hierarchy , calling for social change . Before this , those who are not conformant with this would be exiled from the Isles , but this time things were different . There have been when it was constructive , when they accepted Morgiah as the Queen of Firsthold . But there was a more darker side , in the form of the Beautiful , a radical group that took a more extreme initiative , by attacking the greatest monuments in Altmer history , beginning with the Crystal Tower . There have been several attempts on the tower , but they were all failures , only leaving vandalizing ancient sculptures and emblems . From there , they took to more living representations , for example , they pulled a successful assassination attempt on the Princess of Shimmerene , horrifying the public . During the Oblivion Crisis in 3E 433 , the province of the Summerset Isles was under serious attack from the invading Daedric Force . The cities were ransacked and so the Crystal Tower served as a beacon of hope for the Altmeri , being filled to the brim with refugees and Daedra surrounding the Crystal Tower . They hesitated their attack , and the Altmer had hope , thinking that the Daedra feared them . As the refugees slept , the Daedra brought Altmer prisoners on the outside of the Crystal Tower , before they attacked the tower . Everyone in the Tower woke up to the screams of bloody murder , as the Daedra carved and ate them alive . The wizards of the Crystal Tower fought back with powerful fire magic and Altmer warriors charged with vigor , but it was enough . Many refugees fled the Tower and out of the province , looking back and seeing that the Crystal Tower had fallen to the Daedra , a great loss for the Altmer . Many refugees fled to Cyrodiil , some left for Hammerfell . Eventually , the Thalmor had risen from the ashes and established the Third Aldmeri Dominion . A survivor and hero at the siege , Rynandor had his name besmirched by the Thalmor , even when he saved the lives of Altmer , he was exiled from the Isles .
