Capnolithyl

Capnolithyl, mostly 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 dracoliches. 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, Capnolithyl 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 Capnolithyl placed it in his body to keep it safe.

Notable accomplishments by Capnolithyl are reversing the Vaasan Horde that were 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, Capnolithyl 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 and 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 chromatic dragons, as well as a few gem and metallic dragons. After Tchazzar was freed from Sseelrigoth's prison, Capnolithyl sought the red dragon to invite him to play the xorvintaal as well.
