You just defeated a ghost warrior who called himself, "Umbra" in Champion's Rest. As you loot the warrior's ethereal corpse of its ebony armor, you notice a black two handed sword resting on the ground next to the warrior. The sword is humming with a sinister purple energy. You can also hear a very faint voice beckoning you to touch the sword. However it's so faint you can barely make out what it's trying to say.

Do you pick up the sword? Or do you leave it?
