Greytail
Greytail was a male Sparra tribe warrior. He was the husband of Dunwing and the father of Warbeak.
While Warbeak was still an egg, Greytail went hunting with King Bull Sparra. Bull tried to show off his skills with the sword of Martin the Warrior, but while flying over the Quarry, Bull dropped the weapon and Asmodeus Poisonteeth immediately took possession of it when it fell to the ground. Bull ordered Greytail to retrieve it; when Greytail attempted to do so, he failed and was bitten by Asmodeus before escaping back to the Sparra court.
Poisoned by the venom in Asmodeus' fangs, Greytail soon died of its effects in his wife's wings shortly after his return. Greytail lived long enough to explain to Dunwing what had truly happened, while Bull lied to the others, but did not live long enough to see their daughter hatch.
