Could this be a thing?

I've been on total theory mode since the Yae stuff I came up with. And that led me to making a whole video on it and my predictions for Inazuma.

But researching through that ended up getting me info on Sumeru and the other regions going all the way back around to Travail where this suddenly popped an idea in my head.

So why Resurrection? People who've been following my theories you might remember who I think is the Pyro Archon Murata. So it could be she wants to resurrect her buddies. If I'm right about the event that ties into her background it would only make even more sense because those old wounds would have reopened again and she'd probably want to resurrect them.

What Dainsleif says while this part of the trailer plays is that Murata has her reasons for warring that she'll tell the Traveler. Well the event should happen before this even starts so we wouldn't really need her to tell us but it could play a part in telling us her personality.
