   Summary

   With allies hidden from her, Edelgard von Hresvelg must navigate a new job as a librarian at the esteemed Garreg Mach Monastery until her plans fall apart after the murder of her associate. Joining forces with her mysterious coworker, Byleth, the two are pulled into an anxiety-inducing investigation that leads them to places and beings neither could even conceive of, while the only thing keeping them afloat is their bond.

   A modern AU inspired by murder mysteries and cosmic/eldritch horror that I thought might work within some contexts of Three Houses.
