An Architect Transported to Honkai: Star Rail

To meet her client's demands, Kaveh keeps revising his proposal again and again, but none of the revisions pass. With no other options, he goes out to look for inspiration.

Somewhere along the way, something goes wrong with the ley lines, or something else. After a burst of laughter, he opens his eyes and finds himself in an unfamiliar place.

Kaveh: Where in the world have I ended up?

Astral Express Crew: Would you take in a lonely bird of paradise that fell onto the train? You have to, even if it kills you!

With no choice, Kaveh can only continue pioneering with the train, praying that one day it will reach Teyvat. Until then, he can take the chance to see more of the sights elsewhere in this universe.

Kaveh: So this is the universe? The architectural styles are so magnificent and diverse! I wonder if I could build something like this back in Teyvat.

At first, Kaveh thinks he's just a stranger who wandered into this place by mistake.

But he never expected to meet a "familiar face" in a strange place?

Aventurine: The echo of good fortune!

Kaveh: That voice sounds so familiar. Am I imagining things?

1. If you want to see Kaveh and Aventurine being lovey-dovey little birds, this is a dumpling wrapped in vinegar. The main story is set in Honkai: Star Rail, and there will be memes. If that's not your thing, please don't read.

2. No romance, just friendship. My writing skills are limited, but I'll do my best to capture the characters. OOC is inevitable. And since I'm writing fanfiction, cut me some slack. There will be plot holes and lots of headcanons, so please spare me if you're particular about canon details.

3. The Trailblazer in this story is Caelus.

4. The Honkai: Star Rail timeline is before the train goes to Penacony, and the Genshin Impact timeline is roughly before Song of the Welkin Moon. Anything else that doesn't make sense is a headcanon, such as ley lines causing all the Genshin Impact crossovers, or Aha being involved in the Honkai: Star Rail crossover.

5. I may revise the story often.

6. Updates are irregular.

7. It's probably a short-to-medium-length story.

I'll add more if needed.

Theme: Enjoy this wonderful journey to another world.
