Vermilius

Vermilius was a young green dragon that dwelled within Arkhan's Tower in the plane of Avernus in the Nine Hells around 1494 DR.

Vermilius resided there with three other young chromatic dragons, Flash, Slarkas, and Vistalancer, and the adult white dragon Obatala. Collectively they protected the master of the tower, and servant of Tiamat, Arkhan the Cruel.
