Blackrazor, also known as the Sword of Souls, is a greatsword that appears to be forged from an unknown alloy of steel. It is sheathed in a black scabbard decorated with pieces of cut obsidian. When held, it shines like the night sky filled with stars. The wielder of the sword hears faint whispers whenever it delivers the killing stroke to a living creature. The sword has a sentient being of another plane of existence forced into it. This creature was once a powerful undead creature similar to an atropal.
