Galvan

Galvan was the Blue Dragon Wyrmspeaker in the reformed Cult of the Dragon of Severin Silrajin.

Personality
Galvan thinks very much like a scheming blue dragon. He’s also Talis Kasteler’s mentor and sees Severin as a man of great vision and destiny, and thus would never act against him.

History
Galvan was born in Thay and had aspirations to be a Red Wizard but his magic skill were no enough. He entered in the Cult of the Dragon and served in for a long time; when Severin entered the Cult Galvan saw him as a charismatic leader and soon allied with him. He always maintained contacts among the Red Wizards and under Severin's leadership Galvan acted as link between the two group. There was a secret family connection between he and Rath Modar, the lead red wizard allied with the Cult. Galvan also plotted against Valindra Shadowmantle in hope to acquire or destroy her dragon's orb.

Behind the Scenes
Although Galvan's schede was present in the Wizard site, he was barely nominated in Hoard of the Dragon Queen and The Rise of Tiamat.
