Capnolithyl Capnolithyl , also known as Brimstone , was a vampiric smoke drake and a hero of the last Rage of Dragons . Description . Capnolithyl appeared to be a normal , adult smoke drake with reddish black scales . However that was an illusion used to disguise its undead , vampiric nature . He was also able to change into a cloud of embers and smoke at will . History . Capnolithyl was one of the drakes Sammaster reached out when he was researching a way to create the first dracolich es . He allowed Sammaster to turn him into a vampire , thinking this would win him favor . Sammaster realized the disadvantages of vampires far outweighed their usefulness , and he discarded Capnolithyl . Since that day , Capnolithyl ' s only desire was to see Sammaster destroyed . For that reason , he remained in the North , in the citadel where the final battle against Sammaster took place , waiting and gathering power . In 1373 DR , he journeyed with Dorn Graybrook and his companions , but also did work on his own . Little is known of the time he spent apart from Graybrook . The entire time he traveled with Graybrook , he did not get along with their traveling cleric , Pavel Shemov , a priest of Lathander , who found it hard to tolerate Capnolithyl ' s undead condition . Unlike other vampire dragon , that cannot leave their hoards for large periods of time , Brimstone was able to remain apart from his hoard due to a magical collar that was shattered by Sammaster . A portion of the collar survived , and Brimstone placed it in his body to keep it safe . Notable accomplishments by Brimstone were reversing the Vaasa n Horde that was stirred up by Sammaster to cause confusion and the saving of Gareth Dragonsbane , King of Damara ; and its help in the final battle against Sammaster and the destruction of the mythal that caused the Rage of Dragons . For this reason , dragons across Faerûn hailed him as a hero , although some believed he died in the final battle . After the destruction of Sammaster , Brimstone began to felt a sense of emptiness . He remained in Sammaster ' s fortress searching for something to give purpose again to his life , and he founded it when he came across information about an old draconic custom , the " xorvintaal " . He then traveled across the Outer Planes in order to fully investigate his discovery . He returned to Toril in 1479 DR , and went to Dracowyr to contact the Princes of Murghôm in order to start his own " xorvintaal " . The princes allowed him to contact many other chromatic dragon s , as well as a few gem and metallic dragon s to start the game . To ensure the dragons would play , Brimstone bound them with a powerful spell , although the participants were unaware of this . After Tchazzar was freed from Sseelrigoth ' s prison , Brimstone sought the red dragon to invite him to play the " xorvintaal " as well . When Alasklerbanbastos warned Brimstone about Aoth Fezim and the Brotherhood of the Griffon attempts to foil the " xorvintaal " , the vampire allowed the dracolich to reach other dragon allies , including Tchazzar and a few dragon princes of Murghôm , to attack and destroy the Brotherhood . After the Battle of Luthcheq , the leaders of the Brotherhood of the Griffon , as well as several dragons and dragonborn knights from Tymanther , traveled to Dracowyr to confront Brimstone and forced him to cancel the magic that bound wyrms to the game . Before he disappeared to whereabouts unknown , Brimstone claimed that the game was just a ruse to allow him to eliminate the most powerful dragons around the Sea of Fallen Stars .
