So this was the purpose? Interesting.

I find this very interesting. I never really questioned why they journeyed space before. I just figured it was something they chose to do. But learning that their ultimate goal is to "grasp the true purpose of the cosmos" is quite shocking to me, as well as the fact that it says they're getting somewhat close to an answer. Especially since the traveler is now talking about how they see teyvat as a home now and the only thing missing from their life here is their sibling being by their side. What did/does everyone else think of this?
