Muramasa

Muramasa is a finely-crafted Hashizawan katana, crafted long ago during the war between Kuzutoro and Shailiang. It is a magical blade that can communicate telepathically with its wielder.

The sword lay within the city's ruins for more than three hundred years before it was found by Brecca Greenstone. It promised her the strength to smite her enemies, and so she took it for herself and drew upon its magical power. As time went on, however, Brecca became concerned about Muramasa's obsession with killing and revenge. Eventually it started suggesting, then commanding, that she use it to raise the bodies of her enemies as undead servants. Concluding that the sword was evil, she hurled it into the Inner Sea.

What happened to Muramasa thereafter is unknown, but a wight Brecca encountered in Palmheart spoke her name and told her that "the sword remembers."
