About The Authors
synthofurthesis
Writer. Frontend management.Synth (they/them) is fast and logical, driving ambitious projects forth with unwavering protagonist energy. They love all things sports, fantasy and action-filled adventures and are pushing the arrogant dragon Phainon and Ica product placement agendas in our fics. With unwavering determination, they steer the ship from plot point to plot point while crushing any writer's block iceberg on their way. After navigating through the last straights of post-processing, they emerge victorious to safely deliver the team's fics to ao3.Plum's note: They have a gif folder with cute animal reactions. It has cute bunnies and a side-eyeing cat.
plumpaperbird
Co-writer. Editor. Backend management.Plum (they/them) loves heartwarming stories, interesting world building, dark fairy tales and the Ancient Greek language. When they're not writing, they pretend to be a no-fun person by chugging a lot of coffee and holding important plot and consistency meetings where they put on their big speech voice, make bad puns and try not to grin while discussing the structural intricacies of emotional breakdowns and the acceptable amount of Mydei simping for a particular chapter.Synth's note: To the question of a literal dark pit in one of our fics, they have stroked their chin and commented 'looks like we have a plot hole.'
