Iryklathagra Irklathagra was a blue great wyrm who had long plagued the lands of Amn , Calimshan , and Tethyr and was the long - standing nemesis of Shoon VII . Description . Irklathagra was the perfect example of a blue dragon in her prime , sporting impressive frilled ears and an enormous horn typical of her kind . Due to her long absence from desert environs , her azure scales lacked the usual gloss that those of her breed normally had . Her over - sized fangs were perhaps her most prominent feature and were what earned her the moniker " Sharpfangs " . Personality . Iryklathagra ' s success was mostly due to her cunning and patient nature , eschewing much of the arrogance that is the downfall of younger dragons . Although she was well aware that she was not indestructible , she would stop at little when it came to revenge . It was this type of disproportionate retaliation to any slight against her that had deterred many from moving against the infamous dragon . Possessions . Over a millennia of amassing items and wealth for her hoard , Irylathagra grew to possess one of largest dragon hoards in Faerûn . She had looted from numerous organizations and realms , powerful wizards , and other dragons to create her hoard over the years . Although her monetary wealth fluctuated over the years , her hoard was noted for many precious works of art that were the jewels of her collection , some of these included : In addition to these prized pieces , Irylathagra had managed to attain some of the most unique magical items and artifacts in the Realms , the most notable of which were : Irylathagra did not use these powerful magic items ; she was a hoarder at heart . However , she hoped that her possession of them might someday gain her entry into the Twisted Rune , the secret society of which the blue dracolich Sapphiraktar was a part . Alternatively , they would provide her with protection , should the red dragons Balagos or Charvekkanathor ever choose to attack her . Relationships . Irylathagra was the mother of Araugauthos , a dragon once imprisoned by Halaster Blackcloak in the Undermountain . The two dragons get along well with each other . History . Early Years . Irylathagra was born in 145 DR in the Anauroch Desert . As a wyrmling , she already lusted for riches , and in 150 DR , she looted Halastar ' s abandoned tower and stole his treasure . The Sharpfang Battles . Her first interaction with the Shoon Dynasty happened in 236 DR . Irylathagra was then a young adult dragon . Desiring the hoard of a silver dragon in the Marching Mountains named Rhimnasarl , she conspired together with Emperor Shoon IV to kill the good dragon , as Shoon IV desired his death , since the dragon opposed Shoon rule . After the deed was done , Shoon IV seized the loot for himself . Betrayed , Irylathagra battled with and seriously injured him , but he escaped to Shoonach alive . Afterward , Irylathagra remained in the Marching Mountains and built a lair there , biding time for revenge . ( Even after she moved on to another lair , she continued to guard the " Yawning Cavern " , as it was called , and slew any who tried to enter it . ) By 245 DR , she began a reign of terror in the lands around her lair and built a name for herself in that region . In 322 DR , Irylathagra first battled with Emperor Shoon VII , a fight which ultimately destroyed four villages . Irylathagra had landed in the middle of Qysar ' s Square and requested an audience with the emperor . When he appeared , she demanded he return the treasures of the dragon Rhimnasarl that Shoon IV had stolen from her . Shoon VII refused , and this led to their battling in northeastern regions of Tethyr . Shoon VII emerged the victor , having even stolen several magical items from Irylathagra ' s claws . After that first fight with the blue dragon , Shoon VII became obsessed with destroying Irylathagra . This desire drove him to create the magical artifacts the Staff of Shoon and the Tome of the Unicorn in addition to several powerful and evil spells . In 358 DR Irylathagra fought her second major battle with Shoon VII . Having waited patiently for over three decades , Irylathagra was more powerful . This time , despite Shoon VII ' s powerful new magics , the blue dragon was victorious and even stole Shoon ' s powerful magic staff . In 366 DR , her final battle with Shoon VII left 75 , 000 bystanders dead and destroyed Shoon ' s right leg and left arm . Her own wings were shredded . She was eventually driven off . Shoon VII , however , used his injuries as a ploy to fake his death and become a lich . His successors , terrified of " Sharpfangs " , as they now called her , agreed to pay her tribute for centuries lest she attack again . When the Shoon Imperium fell in the Year of the Corrie Fist ( 450 DR ) , the one - armed , elven prince Strohm I burned Shoonach to the ground . On Alturiak 4 , while the fires were still burning , " Sharpfangs " showed herself to the elven conqueror . When he permitted her to loot the city and reclaim the treasures she claimed were hers , she vowed never to use Tethyr as a hunting ground again — a promised she indeed kept . For his part , Shoon VII , in undeath , bides his time , waiting for when he can kill " Sharpfangs " and retake his magic staff . Later Years . A rage of dragons occurred in 1018 DR , and Irylathagra was driven to attack he city of Mintar . She battled with its defenders for nearly a month before returning to her lair , leaving the city in ruins . In 1162 DR , Irylathagra ' s lair was invaded by members of the Skeletal Finger . They overcame her traps but woke her from a deep sleep and fled . She followed them back to their hideout and slaughtered every last member of that thieves guild . The hideout became her new lair . In 1271 DR , Irylathagra explored the ocean by means of an ioun stone . She plundered the underwater city of Otanyn and stole Kayas the Krakenscourge . During another rage of dragons , in 1373 DR , Irylathagra badly damaged the eastern tower of the Twin Towers of the Eternal Eclipse , which were temples to Cyric . She continued on from there to return to Calimshan again . Unable to attack the syl - pasha ' s palace because of its magical protections , she instead razed the Plaza of Divine Truth , destroying an idol of Bhaelros . This summoned an aspect of Bhaelros , riding a brass dragon . The two dragons fought , bringing further destruction on the Palace Ward of the city , before " Sharpfangs " was driven off .
