- "Once the Sword of Darkness has been drawn, it cannot be sheathed until it has tasted blood."
- —Wulfgar Eisengaard
The Sword of Darkness is a dark sword of the Black Knight of Tes Pellaria. It forces its wielder to kill a person, no matter the allegiance, when it has been drawn. If a person uses the sword to kill its previous owner, the slayer is forced to become the next Black Knight. This is what happened to Ulrik Alefheim after he had killed Wulfgar Eisengaard, the previous owner of the sword.
