Honkai: Star Rail: Don't Make Up Random Lore for My Original Character Cosplay

All characters are platonic, no female lead. The author plays as Qiong, so the Trailblazer in this story is Qiong. The plot starts at Herta Space Station, but won't follow the main story exactly. Some main-story events will change. The author is a student, so updates will be irregular. After being emotionally wrecked by Honkai: Star Rail's 3.4 story, xx finally finished creating their original Honkai: Star Rail character the day before the convention. In an alternate timeline where the Stellaron never boarded the train and the Trailblaze began late, he is the only survivor of Amphoreus, a young man who follows the Path of Nihility. Back on Blue Star, xx forgot to include Aha when creating their original character, so at the convention Aha happened to pass by, mistook him for a souvenir, and brought him to the main Honkai: Star Rail universe.
