"...I don't think I expected that," says Stalas. "Although maybe I should have. Still, no matter, if I have more lyrium in my blood than usual at least I'm hopefully going to bruise less. Thank you, Sable."
"My turn for candy?" asks Milo, approaching Sable's candy-distributing station.
"It's delicious and nutritious and ever so cozy, I love it. I will try very hard to not need to reconstruct a new organic body when I have moved into my rock."
"In our world there is a fluffy alien which wants to grant us a wish and magical powers in exchange for us using those magical powers to fight despair monsters. The magical powers include 'being, technically, a rock, remote-controlling one's body'. This seems like a pretty swell deal, especially since magic rock people do not die of old age and are allowed to use their powers for whatever they want in the off-hours between despair monster fights."
"...Yeah, that sounds like a good deal all right," says Sable. "Here you go, Milo."
"The problem is 'a wish' doesn't mean 'literally any appealing thing I can describe in a sentence'. There's an oomph limit. Solvei has more oomph than I do, but neither of us seems to have enough to do anything good and large-scale. We might just wish for more magic powers to help with despair monster combat - the despair monsters fuel the magic powers, which are pretty freeform."
"If you need to combat despair monsters, I'm coming down more on the side of maybe giving you Terraria weapons," says Sable.
"I would love some Terraria weapons with which to combat despair monsters."
"Terraria weapons are pretty exciting. I'd want to make sure you knew how to use them and could, though, I'm not sure where they fall between 'can't use stacks' and 'can eat candy' in terms of things you can do without whatever it is that makes me Terrarian enough to use stacks."
"Well, how do we check? I could go in the backyard and shoot at trees."
She separates the rest of Milo's Life Fruits and then starts digging in her pockets and pouches in search of a less exciting weapon.
"Not the Last Prism, that's nearly as bad..."
She goes over to the door again. She bumps her hip into a booth-bench in so doing but barely feels it; she laughs. She opens the door, leans out.
"Despair monsters," she reports, on closing the door, "warp space, but insofar as they have sizes they and their customized environments full of minions are, together, bigger than a house."
"Well then. I would actually be willing to fight the Moon Lord enough times to make you a Celestial Staff of your very own, but I definitely want to take you outside and show you what it does first. It's very... very."
Milo has now eaten his last Life Fruit. "How are you feeling?" asks Sable. "That is some exceptionally unnatural health you've got going on there!"
"How does 'the Moon Lord' be a thing you can fight many times? Does it not die, just go dormant...?"
"...There's a coherent explanation but it's a very Terraria explanation and I'm not sure how well I can actually convey it," she says.
"Okay," says Sable. "So first of all, the world of Terraria is a perfectly flat grid of square areas of ocean each with an island in the middle. I started on one island, and explored a bunch more afterward. I don't know how many islands there are in total, or whether they just go on forever in every direction. The island squares are separated by perfectly flat walls of weird magic fog that takes a few seconds to fly through no matter how fast you're going."
