A blade utilized by William of Greenbury. The sword is extremely sharp and able to cut through goblin steel with ease. This is attributed to the fact that the sword was crafted from an angel's feather. Anything sliced by the blade can never be healed, leaving lasting wounds on opponents. Often described as having a "keening" sound when swung.
Role in PGTE
Used as the sole weapon of William of Greenbury in his role as the Lone Swordsman, it was eventually turned into a tool to summon an Angel of Contrition during First Liesse. After the angel summoning was prevented, Catherine Foundling broke it, and scattered the pieces.
