Fashurgrin, the glacier guardian

Fashurgrin, a male silver dragon managed to emerge victorious against his nemesis, Eternal Ice during the events of the Dance of Dragons. Since then, he watches over the Winterwall Glacier, ensuring Eternal Ice remains trapped for as long as they both live.
Befitting his preferred environment, Fashurgrin is described as cold and harsh, but he has a strong sense of justice. Some claim he rules over the city of Frostwatch, the last larger settlement before the vast expanse of the icy tundras of the crown of the world, others say Fashurgrin has never approached civilization since defeating Eternal Ice.
