Official description
A pair of daggers wreathed in chaotic power, originally forged by the people of the Bastion of Mó and identical in design. One was lost when the Bastion fell, drifting through the Discordance for years. The other found its way to foreign lands, where it drank blood without end in the hands of a vicious owner. Reforged time and again, it no longer resembles its former self.
Yet now that the twin blades are reunited, their resonance remains unbroken. Perhaps the bonds of blood are much the same.
