Aela was a child blessed by the Gods. She was a child created and tempered by each and every God who feasted in Valhalla. A child who possessed all their strengths, and would bring great change to the world. A child who would uplift and support all friends, and crush enemies like vermin under foot. A child whose name will be known to anyone who had ears.
She was the child of prophecy.
The Gods are very compassionate. But no great boon such as this comes without a price. Sacrifices are to be made to keep their favor.
