Just thinking about Venti's voiceline on Albedo: How do you explain white chalk in black soil, or the earth's dense crust

Just thinking about Venti’s voiceline on Albedo:

How do you explain white chalk in black soil, or the earth’s dense crust amidst the emptiness of space? Same reason the purest soil gave birth to human life… It’s an ancient power with unmistakable properties. Trying to harness it is dangerous indeed, I can’t imagine what would happen if someone lost control of it in the city… Ah, never mind! What goes on within Mondstadt’s walls is up to Mondstadt’s people to deal with!

Also thinking that if Albedo is going to lose control (highly likely given all this foreshadowing), Venti might sacrifice himself to protect Mondstat. There’s plenty of people who have pointed out all of Venti’s death flags, so I won’t go into that foreshadowing here.

It’s entirely likely that in the event of Albedo’s corruption, Dainsleif will reappear to stop him for good:

But if Albedo were ever to make a single wrong move… I could not let myself ignore it.

If Mihoyo goes for the most tragic outcome, we may end up losing Venti and Albedo.

The traveler’s role in this story gives me some hope though, as I’ve already written here. We may have the ability to stop such a tragedy from occurring. I can’t imagine that Mondstat would actually be permanently destroyed…
