Eric is stumped by this. "Ten platinum bars and eight diamonds can be combined to make a Diamond Staff," he tries.

"Whatever." Dinner is pecans and bananas. "Want some food, Eric?" she asks. It's only polite, and who even knows how he works, maybe he does eat.

"You can make a cooking pot with three lead bars and two blocks of wood," Eric says noncommittally. "Many dishes can be cooked in a cooking pot."

She notes that down for later, but first she heads back outside and hangs out above zombie altitude for a while, blasting flying eyeballs and looking for anything that might be described as a falling star. She might be a little more trigger-happy as regards the eyeballs than is strictly necessary for self-defense; those things are disgusting.

Coins and lenses rain from the sky! So do stars. They're yellow and heavily stylized, and they fall in showers of colorful sparks, destroying any monster they come in contact with as they descend.

Those are some gorgeous stars! The first time she sees one she tries to chase it down.

It sits on the ground, releasing occasional sparks. 

Into the Bag of Hoarding Holding with it! How many more can she get in the next couple hours? She wants to get some sleep before dawn.

Seven stars fall within her field of vision in that period of time.

At one point a cloud is blown by the wind into place a few dozen feet above her, and she hears the sound of a star falling overhead, but it doesn't go past her. A few sparks drift down and fade out around her.

Seven stars is a good number!

That cloud seems to have eaten a star, how odd. What's in there and is it dangerous? (Get wrecked, flying eyeballs.)

Well, if she tries to fly up into it, she bounces off. It's like trying to fly into a very large, oddly shaped marshmallow.

It probably doesn't taste like marshmallow, more's the pity. Time to hit it with her pickaxe! 

Little cubes of puffy white cloud fall and consolidate, as cubes are wont to do. Eventually she breaks through to the top of the cloud.

There's a house built on top of it. Gold and blue bricks, a door with a sun emblem, windows made to let in the currently nonexistent light. Through the windows she can see a chest inside, with another sun emblem on it.

Now she has some cubes of cloud, that's pretty cool, she wonders what she can do with oh goodness she's been mining out somebody's house!

Margaret flies up and looks in the window, hoping whoever lives here isn't mad about their foundation but mostly hoping any kind of person lives here at all.

Nope. There isn't even a bed; there's a table with two chairs, several colorful banners hanging from the ceiling, and the aforementioned chest. It all looks kind of sterile, like an Ikea showroom.

Aaaand there goes the moment of hope that she wasn't the only living mind in the world. She sits on the cloud and feels sorry for herself for a few seconds, then swaps her wings for arm coating of peelable birch bark with discoloration spelling out a note. It says, Hello. My name is Margaret. Sorry for damaging your cloud. I live here: and then there's a map of the island with her building marked with an X.

She leaves this note under the door, then goes back "home" and gets some sleep. Fortunately her magic can make "pajamas" sufficiently fluffy and extensive that they're basically blankets, and she sleeps in decent if unfabulous comfort in a nest of them.

When she wakes up, Eric is standing over her again. 

“A furnace can be made with twenty stone blocks, four wood, and three torches!” he says happily. 

"Gah! Oh, it's just you. Don't sneak up on me in my sleep!" She deletes her blanket-nest and starts starscaping herself clean and fully adorned. When that's done, she sits at her workbench and starts examining her options for making things.

She can make: things!

Some more furniture. Walls, made out of wood, dirt, stone, or clouds. Wooden armor or weapons, if for some reason she wanted those. A campfire. ("Being near a campfire will increase your life regeneration," Eric mentions.) Arrows. She could use some torches to make flaming arrows. A furnace, as Eric mentioned. She could make mana crystals out of her stars.

A furnace sounds good, as does a bed. Can she make both, with the furnace in its own walled room with a connecting door to her living space?

Eric shakes his head. "You can make a bed at a sawmill using five silk and ten wood. You can make a sawmill at a workbench with ten wood, two lead bars, and a lead chain."

Furnace and connecting door works, though. Despite the roaring flame within the stone chamber, it only emanates about as much heat as the back of a refrigerator.

Can some of those shackles the zombies dropped be turned into a lead chain?

The furnace will allow her to melt them down into iron bars, one bar per shackle! Then she can turn a bar into ten chains at a workbench.

"Lead and iron are interchangeable," Eric notes.

Does he just mean that in terms of making sawmills, or what? As soon as her sawmill is done she turns one of her finger-scales into a magnet and checks whether lead and iron are in fact still different on that score.

...nope, lead is magnetic now apparently.
