This foul blade has had many names, and it’s origins are lost, but it is known that the longsword is capable of terrible deeds. This nefarious weapon bears an elegant hilt and crossguard made of a strange black metal and a black leathery material respectively, with intricate designs from a forgotten era, but when activated releases a blade made of pure darkness, a gash in reality itself, cutting through all matter with ease.
