At least for the moment. I worked through the story in visual beats. I'm not sure at the moment what is lacking, or what can be cut. But this is what I have right now. Places where the text and my handwritten notes vary, the text is a revision.

The mothlike man and moon
The magnificent world

A breeze leads to the discovery...

An underground city

An unguarded gate

The only sound is their labored breathing and the occasional scuff of hoof on tile

A girl of the city

Where's your glow? Where's your plug?

No plug!

The machine that powers the plugs

The thinkers, who "control" the machine

The machine isn't producing enough energy

"You have no plug, you can help us." (
you can go where we cannot)

"I don't think I can help you."

"This part will fix the machine."

The girl leads them to the machine

Alone inside the machine

"You fixed it!"

"We're saved!"

"Now we'll plug you in so you can stay!"

"I'm leaving now. Will any of you come with me?"
