Midarr was a world, a planet situated within the galaxy. From Dol'har Hyde, a planet found in the Outer Rim Territories, the Burnsi Run hyperspace route stretched toward Midarr.
During the time of the Imperial Era, the individual Beol De'Rruyet, who was the leader of De'Rruyet Industries, conducted business on this world. Having acquired a Nihil Path engine from the smuggler known as Remy while on Corellia, De'Rruyet had plans to publicly reveal the hyperdrive during an exhibition held on Midarr. Following this, both General Vukorah of the Unbroken Clan and the renegade archaeologist Doctor Chelli Aphra—who had been employed by Domina Tagge, the head of the Tagge Corporation—had the goal of journeying to Midarr to locate the Nihil technology.
The planet Midarr was referenced in the comic Doctor Aphra (2020) 8. This comic was penned by Alyssa Wong and put out by Marvel Comics on March 24 of 2021.
