Reventine was a planet in the Seswenna sector of the Outer Rim Territories, two star systems away from the planet Eriadu. In 228 BBY, Republic Defense Coalition forces led by Jedi Knights Bell Zettifar and Burryaga Agaburry theorized that Reventine would be the next planet targeted by Nihil marauders led by Storm Melis Shryke. However, Defense Coalition forces instead encountered Jedi Master Avar Kriss, who had escaped the Nihil-controlled region of space known as the Occlusion Zone using Shryke's starship, the Cacophony.
Reventine was a populated planet in the Outer Rim Territories' Seswenna sector. It was located in an empty region of space two star systems away from the planet Eriadu.
In 230 BBY, the anarchistic faction of marauders known as the Nihil deployed the Stormwall, separating several sectors of the Outer Rim from a region of Nihil-controlled space known as the Occlusion Zone. In 228 BBY, the Stormwall expanded to a point bisecting the Seswenna sector. The new border was at a position near both Eriadu and Reventine.
Following the Stormwall's expansion, Jedi Knights Bell Zettifar and Burryaga Agaburry and Republic Defense Coalition technician Harlak pinpointed Reventine on a star map they were studying as the next world that Nihil Storm Melis Shryke was likely to pillage and began concocting a plan to trap Shryke and her forces there. The Seswenna sector had indeed been the next target for Shryke's forces to raze, with the marauder noting that it would be her first raid so far out and on such a populated place; however, Jedi Master Avar Kriss had hijacked Shryke's starship, the Cacophony, above the planet Seswenna before the mission could take place. As a result, when the Cacophony emerged near Reventine, the Nihil were not present. Instead, the Jedi and Republic forces discovered Kriss, who had utilized hyperspace information from an EX droid to slip through the Stormwall unscathed, with Shryke in tow as a prisoner.
Reventine was depicted in-universe on a map in The High Republic: The Eye of Darkness, a 2023 novel written by George Mann as part of Phase III of The High Republic multimedia project.
