Do You Recall? I Believe I Mentioned When I Venture Into Battle I Wield A Certain Sword. And That Weapon

Do you recall? I believe I mentioned when I venture into battle I wield a certain sword. And that weapon is a memento of his.  The magic blade: Heartspan. It may be a nameless item from an eastern land, but apparently quite the myth surrounds it… The sharpness of Heartspan’s bladed edge is authentic. so much that if you  but leave the threads alone they shall twine themselves back together. Of course, that is only if I am the one wielding the blade. That man died and left this as a memento mori.
