Wyvern Head

Wyvern heads are loot from wyverns when they are killed. If you met Coran and accepted his subquest, you can hunt one wyvern down and sell its head for 2000 gold coins to the governor of Beregost. Other heads can be sold to Officer Vai or at stores that will buy this item.

In-game description
"The severed head of a wyvern is both a fearsome and a reassuring sight. Gruesome as its fanged maw and balzing eyes may be, there is consolation in the knowledge that can be conquered by mere and lowly mortals."
