A pike was owned by Zabrak assassin Savage Opress. He used it to kill Jedi Master Halsey and Padawan Knox at the Temple of Eedit on the planet Devaron. It was said to be enchanted by Nightsister magic.
The central spear could be fired as a dart from a trigger in the axe's handle. This was given to him shortly after he was transformed to be more brutally powerful by the Nightsisters.
