Greytail

Greytail was a Sparra tribe warrior, the husband of Dunwing, and the father of Queen Warbeak.

While out hunting in Mossflower Woods with King Bull Sparra, the King ordered Greytail to retrieve the sword of Martin the Warrior from Asmodeus, an adder who had taken possession of the sword after Bull dropped it.

Greytail attempted to do so, but was unsuccessful and Asmodeus bit him, fatally. The poison killed Greytail, and he only lived long enough to return to the Sparra court and explain to Dunwing what happened.
