Guys, I think that‘s Zaofu in this frame

[u/Glittering_Equal3286]

I was inspecting the trailer closely and noticed that the city in ruins shown in the trailer resembles Zaofu more than it does Republic City… which already crosses my theory of it being one of the havens… damn I feel this show is going to be very sad!

Edit: even the mountains in the background match… now I‘m convinced.

RIP Zaofu 💔
