The now-destroyed Lost Library of Nelgenam was a library that had been erected on the idyllic planet of Nelgenam. In the past, the library was a well-known destination for numerous individuals journeying to the planet. However, it descended into a state of disrepair and collapse following the devastation inflicted upon Nelgenam by Nihil marauders who set the world aflame. It was widely believed that the library was nothing more than a legend, but the cartographer known as Emil Graf managed to obtain the planet's navigational data from the First Order, leading him to explore the library's remnants.
