Bell Zettifar used his lightsaber sometime during the emergences on Elphrona to defend himself and others during a raid on the planet perpetrated by the Nihil.
Months after the attack on Elphrona, Zettifar used his lightsaber on Valo during a Nihil attack during the Republic Fair being held on the planet to save some trapped civilians from drowning on the Innovator which was sinking due to the attack. Later, he used his lightsaber to cut some fallen debris to allow a shuttle carrying Supreme Chancellor Lina Soh's son Kitrep Soh to leave the submerged ship. As Zettifar held onto the shuttle's hull as it left the hangar, he lost hold of his lightsaber, leaving it submerged inside the Innovator.
