The Obsidian Lance, a weapon resembling a spear, was constructed using the sharpest obsidian sourced from Mustafar and forged by the Mustafarians. These weapons frequently featured runes and sigils, etched into the spear's main body. A variation of this weapon was known as the Oppressor obsidian polearm.
The Obsidian Lance made an appearance in the Star Wars Galaxies video game, a massively multiplayer online role-playing game created by Sony and released by LucasArts, before the game's servers were shut down on December 15, 2011.
