Freia Greymoon

Mister Cornelius offhandedly mentioned someone named "Freia" while speaking to Group Alpha, and for a time nothing was known of her.
Eventually, however, Group Alpha discovered that she is the leader of the Knightly Order of the Sacred Moon, as well as the daughter of Luca Greymoon. Freia showed herself to be fierce, but kind, and even after Lucien Novelle claimed to be Luca Greymoons son, she remained calm and accepted his apology at the deceit. She also showed great respect to Factus Formis, a fellow Dragon Slayer, even granting him Storm Aegis, The Dragon Slayer Armor.
Using Lucien Novelle's Knowledge of Whiterock Keep, and their teleportion circle, the Silent One sent a trio of Hushed Lords to eradicate every inhabitant of the keep. They faced Freia in an intense, terrifying battle. Eventually Freia succumbed to the powers of the Hushed Lords, being disintegrated by Constance Von Ducall.
Left were her ashes, and the yellow vestige, a pole arm previously wielded by Freia known as Cloud Cleaver. Lucien Novelle used her ashes in a ritual to see the events that had led to her demise. He is also the current owner of Cloud Cleaver, which had been purified by Group Alpha, but retained magic power.
