Evat Seth was a Jedi Master from Czerial who served the Jedi Order in the High Republic Era. Around the year 379 BBY, Seth had aged considerably, and their Padawan, Rooper Nitani, considered Seth to be the most skilled lightsaber combatant she had ever witnessed. Before Nitani's Jedi Trials, she perceived Seth—along with several other Jedi—while in a meditative state on the planet of Batuu, identifying them by the unique color of their aura in the Force.
The short story "Shield of the Jedi," penned by George Mann, featured Evat Seth. It was included in the young-adult collection The High Republic: Tales of Light and Life, released in 2023 as part of the larger Star Wars: The High Republic project spanning multiple media formats.
