Zuko was just making a late visit to the turtle ducks. The glowing, chiming plants which the reptile-birds have discovered might have been cause enough for curiosity, but that thing across the river is about as conspicuous as they come. It's also a bit alarming, although whatever it is, Paarthurnax seems to have it under control.

Still, she finds herself making an absent and entirely unnecessary 'stay here' motion to the turtle ducks and making her way across the river. Closer up, it's most definitely not a statue; those are gears. And it seems to be... steam-powered?

"What is that thing?" It's like some sort of machine soldier. In the back of her mind, she wonders if there's some world where this qualifies as a person. It doesn't, right?
