Gretta the Arbiter in Brunnhildar Village wants you to go to Valkyrion and obtain Vials of Frost Oil from the Valkyrion Aspirants. Use the Vials of Frost Oil to destroy 30 Plagued Proto-Drake Eggs.
It is not enough to demonstrate your prowess among your peers. You must also fight our enemies, dear sister.
The Valkyrion traitors continue to mock our noble drake-riding traditions by rearing plagued proto-drakes.
Seize the frost oil they wield and use it to freeze their abominable plagued eggs.
