Sanguine Prudence is a sword which was the family heirloom of Alexis Luchester and her descendants. It disappeared during the Yamatian Invasion of Remon when Alexis's descendant Dorças Luchester lost her life, and the sword's current location has remained unknown since.
The sword is polished black and has a crimson handle inlaid with garnets. The blade is like any other sword, except at the tip. It has projections that curve outwards and point inwards to the inner tip, like a deformed pitchfork.
