The Lord Ruler is in his palace, when he sees a sight he hasn't seen in centuries. Trees, sunlight...is he hallucinating? The fact that there's a forest in his living room isn't the surprising part. The fact that there's a forest on his planet is. As soon as he walks through the door to where his living room isn't, it's definitely not a hallucination.

His stores of Allomantic metals abruptly disappear. They're still physically there, but the power is completely gone. He immediately turns to go back, only to see more forest.

At least his Feruchemy still works—he can tell because he's still alive—but that won't last him forever. He only has so much stored youth, and without both sets of abilities he can't replenish it. He hasn't been in so much danger since the beheading that one time. Returning to Scadrial is the highest and currently only priority. If spontaneous forests are a thing, he needs to find someone who can explain them and more importantly how to get back.

The next few hours are spent walking in an essentially randomly chosen direction, with the sun to his right. He's quite certain that suns are supposed to be moving across the sky, but that's not a pressing emergency. He already knew he wasn't on his own planet when he saw proper trees and plants instead of ash-covered monstrosities. Whenever he calls out, nobody responds. If it's an empty spontaneous forest, he's probably doomed.

After some time, he hears his stomach growl. He hasn't seen much that looks edible, but possibly that's just because he's not used to real plants. Berries. Berries used to exist. Those berries look tasty, and if they're poisonous it's not like he needs to worry about it. As always, he has a truly ridiculous amount of stored health in his gold jewelry. Tapping gold just in case, he eats a handful.
