Den va Seignon Family Sword (artifact)
The family blade of the Den va Seignon family has seen use in hundreds of battles over four centuries. Initially discovered by the (self-styled) King Credon den va Seignon shortly before the Red River War, in an ancient crypt of unknown make, its glimmering black blade seemingly fades in and out of vision as it cuts through the air with a sickening hiss. The metal and style of the blade are a mystery to all who have seen it, as is its ability to cut through sight itself.
