Freyja

Freyja is one of the Valkyries - a powerful Demi-Goddess from Valhalla that is featured in Valhalley of the Dolls, Part 1 and 2. She appears to be the leader or main Valkyrie as she seems to be the voice of reason and direction. Although not stated, because she is the leader of the Valkyries, she is highly likely to be the Norse Goddess Freyja. The only possible proof of this is when Chris Halliwell referred her to her as a "legendary being", possibly referencing her importance, her reputation, authority, powers, and her possible status as a goddess.
