Sol dreamt of a strange world...

...full of rules and wonder...

They journeyed on until...

Sol awoke in an unfamiliar dark cave!

This seemed to alarm a mysterious knight
who ran off in a hurry.

Oof...I'm awake now, right?

Who was that knight?

...And where am I?

You're in Null Point — a faraway cave,
high up in the mountains.

AH! Luna, where'd you come from?!
I thought you were just part of my dream!

That's usually the case, yes. I was able
to follow you here using my powers...

...but I can't stay for long. I'll have to
leave and rest for a while after this.

Really...? But I still don't
remember anything about myself...
what will I do after you leave?

Don't worry, Sol...I think there's a
solution to your lost memories. Remember
the teddy bear you found earlier?

Oh yeah...I heard a voice when
I held that bear. It seemed familiar.

Exactly. I believe there are
other objects in this world that will help
you unlock memories of your past.

...And I'm sensing an object like that at
the exit of this cave. Sol, you must find it by—

Woah! Luna, what was that noise
just now?!

How can this be...?
Sol, the exit is caving in!

W-what?! What should I do??
We need to get out of here!

Hmmm...first, let's stay calm.
We still have time, just less than I thought.

You can do this, Sol — escape the cave
by using your rewriting power!

How can I do that...?

Look around you...doesn't some of this
seem familiar?

...Oh, you're right! It looks a little different, but there are objects, blocks,
and rules here like the ones in my dream.

Indeed. This cave has objects
like rocks, mushrooms, and fossils.

As for object blocks — there's a block
for mushrooms, Sol, fossils, and gold.

Yeah! There's also the connector block...

And a state block. Hmm, this one says SINK.
I don't think I know that one.

Can you tell me what it means, Luna?

Hm...remember Sol, I won't always
be here to give you the answer.

Instead, I can show you how to approach
problems that are new or unfamiliar.
That should be more useful for you.

After all, the first step to solving
a problem is to understand it.

And the more you understand a
problem, the more your rewriting
power ​grows when you WIN.

Really? Okay then, I'll try...
but where do I start?

Let's try this — make new rules with the SINK block by using these 3 object blocks.

...New rules? So I should try
making SOL IS SINK, FOSSIL IS SINK,
and GOLD IS SINK?

Yes. Each time you make a new rule, pause 
and notice what happens. That should help you understand SINK and solve this problem.

But remember, it's okay if you don't solve
the problem right away. What's important is
that you try to understand it first.

Right...I just need to try my best.
Let's do this!

What did you notice when Sol pushed the fossils into the mushrooms?
