Jenny Cornelius's lightsaber
From Jenny Everywhere Wiki
Jenny Cornelius owned what was very obviously a lightsaber, claiming to have acquired it somewhere “far, far away”. When Mister Fell found himself of a flaming sword with which to fight a Hound of Tindalos, she offered to lend him “her own” and gave a surprised Fell the lightsaber's hilt before showing him how to make the blade appear. After he dispatched the Hound with it, Fell returned the weapon to her, inquiring as to its origins, as he was still unsure it could seriously be called a “flaming sword”. (PROSE: Dog Days of Sumer)
