Brimstone is a vampiric smoke drake who was instrumental in the destruction of the mad Lich Sammaster. Believed to be dead by his comrades, he remains in the North, in the citadel where the final battle against Sammaster took place, waiting and gathering power. During the Year of Rouge Dragons, 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.

He can 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 are reversing the Vaasan Horde that were stirred up by Sammaster to cause confusion, help leading to the destruction of the Mythal that caused the dragon rage, and the saving of Gareth Dragonsbane, King of Damara.
