Oathcarver is a sword of radiant silver forged in the fires of rebellion and quenched in Gwenivire’s own vow. Its hilt bears the shape of an open gauntlet and the sigil of the unbroken chain.

Awakening Trigger:

Oathcarver awakens when its bearer defends someone despite great personal risk, or upholds honor in the face of overwhelming corruption, betrayal, or despair. The sword draws power not from righteousness, but from sacrifice in service to others and devotion to a cause greater than self.
