Before the events of 34 ABY by many Centuries, Nelgenam, once a paradise planet, was set ablaze by Nihil marauders. In this destructive act, the Nihil annihilated a well-known library. Sometime between 34 ABY and 35 ABY, the cartographer Emil Graf made a trip to the devastated library on Nelgenam. CR-8R, his monster droid companion, told him about the devastating fire, noting the planet's previous state as a paradise before the Nihil's arrival.
Cavan Scott penned the comic story "The Lost Stories, Part 1," where the torching of Nelgenam was referenced. This story appeared in Star Wars Adventures (2017) 30, a comic book released on January 29, 2020.
