Where's the Honkai We Were Promised?

I transmigrated into a Honkai crossover world! It has not only the Honkai Gakuen cast, but also Honkai Impact 3rd, the Previous Era, and even characters from the Zero Era! Elysia is a streamer, Vill-V is a magician, and Eden is touring the world with her concerts! Kiana’s whole family is together, the angelic Sirin was adopted early by Cecilia, and Durandal is still the big sister of the group! When I first transmigrated into this world, I thought Honkai was going to pull some huge stunt on me. Here, even the Herrscher of the End would only be a foot soldier. So I spent two or three years working hard to prepare for battle and build up an organization, but I never saw a trace of Honkai, nor any records of its history! That was when I realized that Honkai simply didn’t exist in this world!
