392 BBY, which stands for 392 Before the Battle of Yavin, marks a significant year within the 'ABY-BBY' dating system, falling squarely within the High Republic Era. During this time, the Galactic Republic initiated the sponsorship of missions carried out by Pathfinder teams consisting of both Jedi and Republic Pathfinders. These teams were tasked with charting new and secure hyperspace routes located in the Outer Rim Territories, thereby facilitating the expansion of Jedi knowledge and extending the Republic's influence. Concurrently, the Quarren Republic's leader, Orlen Mollo, successfully mediated a territory dispute that had arisen on the planet Mon Cala.
The year 392 BBY was initially brought to light through an oblique reference to an event occurring a decade before the events depicted in the 2022 novel Convergence. This novel, penned by Zoraida Córdova, is a component of the Star Wars: The High Republic multimedia project's Phase II. The specific designation "392 BBY" was explicitly used in the reference book titled Star Wars: Timelines, which debuted during Celebration Europe, held from April 7 to 10 in 2023. Prior to the official release of the book, a mention of 392 BBY was featured in a March 8 episode of Star Wars: The High Republic Show.
Within the context of Star Wars Legends continuity, the year 392 BBY received an indirect mention in The DarkStryder Campaign. This campaign, set in 8 ABY, alludes to an event taking place four centuries earlier.
