[This is a crossover of Genshin Impact, Honkai Star Rail, and Zenless Zone Zero.] Somewhere in the vast cosmos, a traveler and her guide ended up in a familiar yet unknown world, joined by a group of trailblazers, a proxy duo, and venturers of the outside forces of the universes. Three worlds vastly filled with history and boundaries, collide together into one big realm, as they must work together to survive while uncovering the dark secrets and an enemy that threatens the very reality they live in.
