The Academy of Mystery and Trickery

''Huh, you haven't heard about it yet?''''Then you must be fairly new to this academy, right? As your tour guide, let me tell you all about our traditions and festivities.''The moon was suspended in the dark blue sky, as if hung by puppet strings. The branches shook and shiver by the oncoming freeze, and the cold hallways became even colder with the coming autumn. A school was built on the lofty moors, its gilded roofs shining black under the midnight stars. All students, whether from the farthest reaches of Teyvat to the closest, were to attend this mysterious academy upon receiving an unsigned letter.And all it came with was a raven's feather, no less. This work is for Day #1 of the Genshin Halloweek event. The prompt used is ''dark academia''.
