Gullveig

Gullveig is a character from Fire Emblem Heroes. She is an antagonist of Book VII. Gullveig, the Golden Seer, is a being with control over time. In the future, she brings Askr and Midgard to ruin. When the Order of Heroes confront her, she undoes its members each in turn, returning them all to a moment in time before their births. The goddess of light Seiðr imparts these events to Kiran as a vision to warn them of Gullveig's threat so that this ending can be averted.
