Vermilius

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

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.
