Remembrance of Maliketh, the Black Blade, hewn into the Erdtree.
The power of its namesake can be unlocked by the Finger Reader. Alternatively, it can be used to gain a great bounty of runes.
Maliketh was a shadowbound beast given to his Empyrean. Marika's sole need of her shadow was a vessel to lock away Destined Death. Even then, she betrayed him.
While Remembrances can be duplicated more than once through different Wandering Mausoleums, they can't be traded for a copy of an already obtained item in the same playthrough.
