Welcome aboard, Trailblazer. I'm Himeko, navigator of the Astral Express. I'm sure we're about to embark on a fascinating journey together.

I'm speculating, but I think the Express departs from Akivili's home world and returns there before starting the journey anew. So the Express doesn't have a "final stop" per se — it's up to you where you disembark.

When we scour the universe for the things we seek, most of the time it's less of a "Eureka, I found it!" moment and more of a "Is this it? What if I'm wrong?" moment.
