Galvan

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

Personality
Galvan thought very much like a scheming blue dragon. He was also Talis Kasterel's mentor and saw 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 was not great enough. He joined the Cult of the Dragon and served 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 a link between the two groups. There was a secret family connection between him and Rath Modar, the lead Red Wizard allied with the Cult. Galvan also plotted against Valindra Shadowmantle hoping to acquire or destroy her dragon's orb.

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