Dagger of Mortis/Legends

"He who wields the blade will be able to control my brother."

- The Daughter

The Dagger of Mortis, also known as the Mortis Dagger, was a blade that was kept in the underground Altar of Mortis. It was capable of killing such Force-wielders as the Father, Son, and Daughter. During the Clone Wars, Jedi Master Obi-Wan Kenobi and Jedi Knight Anakin Skywalker attempted to use the Dagger of Mortis to kill the Son, but when the Son stole it and tried to kill the Father with it, the Daughter sacrificed herself to protect her father.
