The most powerful warriors in the village are granted flame-imbued talismans that give them the ability to control powerful, savage proto-drakes. If we can gain control of one of these drakes, perhaps we can use it to neutralize the threat posed by Voldrune.
The Dragonflayer flamebinders create the talismans and imbue them with power. Kill them and take the talismans.
Did you collect those talismans?
With the talismans in hand, the drake will have no choice but to obey you. I can't wait to see the look on the thane's face when he realizes you've commandeered his proto-drake.
