Nolaloth Nolaloth , more completely known as Nolalothcaragascint , was a crystal great wyrm that was asked by the Illefarn Empire to destroy their great Guardian following the fall of Netheril . War with the King of Shadows . The Guardian had been created from one of Illefarn ' s greatest champions , his soul tied to the ancient Weave to become a construct of power great enough to deter Netherese attack . But when the Netherese arcanist Karsus , fearing the empire ' s destruction by the life - draining phaerimm s , cast the " Karsus ' s avatar " , and then - goddess of magic Mystryl sacrificed herself to save the Weave , the Weave ceased to exist long enough for the Guardian to lose its power source . Instead of accepting its fate and dying , however , it linked itself to Shar ' s Shadow Weave and became the King of Shadows . Following the King ' s defeat of several mighty Illefarn warriors , the ruling council of Illefarn asked the great wyrm Nolalothcaragascint to destroy it in exchange for a massive addition to his hoard from the empire ' s coffers . The dragon accepted , and flew into battle . A titanic struggle erupted that shook the Sword Coast , but in the end the King of Shadows overcame the dragon and struck him to the earth , creating a massive valley in the Sword Mountains which remains to this day . The dying Nolaloth was " saved " by the ruling council , which transfigured his heart into an enormous floating crystal , into which the wyrm ' s soul was laid in a process reminiscent of the crafting of a lich ' s phylactery . Thankfully for Illefarn , the dragon ' s sacrifice was not entirely in vain : the King of Shadows was so badly injured in the battle that it was forced to retreat to the Plane of Shadow to recover , where it remained for over a thousand years . Advisor to heroes . Over the centuries , the great wyrm ' s valley became an oasis of fertility in the Sword Mountains , warm year - round thanks to the heart ' s influence , and a haven for young dragons of all species . Though immobile , the great drake could still speak , and people occasionally came to him to learn , particularly about the King of Shadows . First to come were the githyanki . Approximately a thousand years before the events of " Neverwinter Nights 2 " , the King of Shadows made its first forays into the universe outside the Shadow Plane . It forced open a portal into the Astral Plane , sending its Nightwalker avatar to attempt conquest in the name of now - defunct Illefarn . The giths ' silver swords were enough to fight it off , but at a terrible cost in lives , and the King simply shrugged and recreated the Nightwalker . The Lich - Queen Vlaakith sent her warriors to Faerûn to learn more of her people ' s seemingly indestructible foe , and found Nolaloth in his valley . He advised them to attack the portal itself , extracting a return promise that the githyanki would return him to life . The githyanki were successful , but either forgot or ignored their promise . In the mid 1300s , the - Neverwinter arch mage Ammon Jerro , while studying in his time off , uncovered information leading to the King of Shadows , information that explained some recent strange happenings on the Sword Coast North . His search for answers eventually led him to Nolaloth , and in exchange for the same promise he extracted from Vlaakith ' s emissaries ( to return him to life ) , the dragon informed him of the githyanki ' s success against the King with their silver swords , and told him of the mightiest silver sword of them all : the Silver Sword of Gith , lost with its wielder millennia ago in the Nine Hells . Only the Sword of Gith might have the power to unmake the King once and for all . Jerro immediately left for the Nine Hells , recovered the Sword with the aid of Levistus , Lord of the Seventh Circle , and then led a force of Neverwiner ' s soldiers into battle against the King of Shadows in the Mere of Dead Men . The King was once again defeated , but the Sword was shattered ( one shard burying itself in the chest of the infant Kalach - Cha ) , and Ammon Jerro was blown into the Hells . Encounter with the Kalach - Cha . In either late 1374 DR or early 1375 DR , the Kalach - Cha , now Knight - Captain of Crossroad Keep , was informed by his / her githzerai ally Zhjaeve that he / she needed the Silver Sword of Gith to defeat the now - thrice - resurgent King of Shadows . Ammon Jerro , having escaped from the Hells and now working with the Kalach - Cha , told him / her of how he had learned from Nolaloth . The party immediately left for the dragon ' s valley . As they stood below the great crystal heart , they noticed a pair of black dragon s perched on the cliffs above , simply watching them . They proceeded warily into the northern passage , where they encountered Nolaloth himself . At first Nolaloth refused to help them , his ghostly head vanishing , but then the Kalach - Cha mentioned the return of the King of Shadows . Nolaloth agreed to help them , telling that to reforge the Sword of Gith , they must return to where it was broken : a scar on the earth in West Harbor . This time , the dragon was tired of living half a life , and asked the Kalach - Cha to repay him for his aid by destroying his heart , and freeing him from his torment .
