Fay was a near-human Jedi Master of the Old Republic who perished during the Clone Wars. Of legendary status, it was rumored that in all of Fay's decades as a Jedi, she had never once raised her lightsaber in combat. Some Jedi were unsure she even carried one. Fay's beauty never diminished during those decades either, giving her an ageless quality. When the Clone Wars engulfed the galaxy, Fay did not hesitate to step up and defend the Republic and the Jedi.
One of the more sinister plots hatched by the Confederacy was the creation of a chemical weapon aimed to annihilate Republic soldiers as well as civilians. Jedi Knight Obi-Wan Kenobi had discovered the plot on the Naboo moon of Ohma-D'un where the weapon was tested on a colony of Gungans. Obi-Wan's investigations led him to the planet of Queyta where he met up with Fay and three other Jedi Masters, some drawn to the planet through investigations of their own, some drawn by the Living Force. Fay was not the only Jedi of legend to join the team. Jedi Masters Nico Diath, the Bothan Jedi Master, Knol Ven'nari, and secretive Master Jon Antilles offered a strong presence.
Queyta was a volatile planet, with lava flows crisscrossing the landscape. The chemical weapon factory was actually located on an island in the middle of one lava flow moving it in the direction of the fiery river. The Jedi sought to obtain a sample of the weapon's antidote to return to the Republic for mass production. This prize was sought at any cost. Readings from the factory showed little more than a skeleton crew, as the production was mostly automated. Unfortunately that crew included Dark Jedi Asajj Ventress and the cyborg bounty hunter, Durge. Making their way to the synthesis lab to secure the samples, Fay and the Jedi ran into the two Separatist commanders and a raging battle ensued.
