Talzin's sword/Legends

Mother Talzin's lightsaber was a weapon used by Mother Talzin during the Clone Wars.

Description
The weapon's emitter closely resembled the face of Malmourral, the demon worshiped by the Frangawl Cult. The blade produced from the "mouth" of the hilt was green and smokey, and when swung left green mist in its wake. The weapon produced a softer sound than ordinary lightsabers.

Zardossa Stix
During the Clone Wars, Talzin gained the allegiance of the Frangawl Clan of Bardotta, who came to worship her as the Great Mother. The cult gathered the Living Force from several Dagoyan Masters and kidnapped Queen Julia and brought her to a ziggurat on Zardossa Stix to steal her life force as well. Talzin arrived on the planet as the ritual began, but she was confronted by Jedi Master Mace Windu and Representative Jar Jar Binks. Talzin summoned her lightsaber from spirit ichor and battled with the Jedi, but Jar Jar managed to free Julia and shatter the sphere containing the stolen force, causing a massive explosion. Talzin disappeared after the battle.
