A tragic massacre occurred at Anx Minor in the time before the New Republic began its campaign in the Cerberon system, specifically during the Galactic Civil War. Approximately around 5 ABY, New Republic Intelligence identified the Anx Minor massacre as potentially connected to the Galactic Empire's 204th Imperial Fighter Wing's actions. This event was subsequently examined by New Republic Intelligence agent Caern Adan along with Yrica Quell, his fellow agent. Quell observed resemblances between the massacre and the 204th's raid on Beauchen, but also pointed out its geographical isolation compared to other incidents they had been investigating on her and Adan's map.
Alexander Freed included the Anx Minor massacre in his 2020 novel, Shadow Fall.
