Weapon, unique (requires attunement)
The story of the ill-fated Margreve Knights, adventurers who perished in the heart of the woods, is little remembered except in the name of this strange sword. To all appearances, this sword that has been shorn down the middle of the blade. It functions as a +1 longsword that’s light enough to be used as a finesse weapon. The half-sword of the Margreve Knights scores a critical hit on a roll of 19–20.
Legend says that the second half of the blade lies forgotten in the Margreve and, if the halves are rejoined, it becomes a vorpal blade.
