Edit: I am not going to remake this.

So, apparently you, everyone in your universe, fell down a portal, and ended up in Teyvat, a new and unfamiliar world for you, since you were only used to whatever stuff was in your daily life.

So, well. You're somewhere, just somewhere in a forest with other, many, unfamiliar people and some people you know. Now that your in Teyvat, what do you do??
