Gladius Dux (BSN)

The Gladius Dux

The Gladius Dux (支配者の剣, Shihaisha no Ken), known as the "Sword of the Commander", is a key item exclusive to Bladestorm: Nightmare. Once owned by a forgotten race, this ancient artifact has the power to control monsters and slay supernatural beings.

Joan of Arc discovers the sword at Nantes and hands it to the protagonist upon being captured. Its effects on the monsters are initially feared by the English and French armies, though the relic is eventually viewed as their only means of salvation against the demonic horde. After the defeat of Diabolus, Joan throws the sword into the ocean so that no one can ever abuse its powers.
