It is Grass/Steel! Glad you like it—I had a part in designing it. Yokaiju did a great job with all his artworks here, and shows a lot of personality.

DERRY (final phase):
Go on...
🔥Put me out.🔥
Just one little blow.
That’s all it takes, right?

You’ll leave, and the barn will go dark.
Just like it always does.
Just like I always do...

...at least this time...
someone saw me.

DERRY (enraged):
You think you can just walk in here
with your little team
your little purpose—

🔥HELL, I WAS THE LIGHT.🔥
I LIT THE WHOLE NIGHT SKY!!
I CARVED MYSELF INTO EXACTLY WHAT THEY WANTED
And they STILL
THREW
ME
🔥AWAY!!🔥🔥🔥

6/?

DERRY:
They lit me up for one night.
Then left me in the rain.
You know what pumpkins do in the rain?
🔥THEY R O T.🔥
They split.
They fall off the porch
and no one picks 'em up...

5/?

DERRY:
You ever feel it?
That wind...
slipping in through the cracks...
🔥trying to put you out...🔥
just because you dared to shine.

They called me creepy.
Then boring.
Then too much.
🔥So I carved myself smaller.🔥
Took out the parts that made 'em squint.
Now I'm just how they wanted.
🔥hollow.🔥

4/?

DERRY:
I just need to burn BRIGHTER—
🔥BRIGHTER THAN ALL OF THEM!!🔥
Take that little flicker of yours
and turn this place into a BONFIRE!!🔥🔥🔥

>The smile finally splits open—his carved face widening into something jagged and flaming.

Come on then.
Let’s see which of us..
was meant..
to 🔥SHINE.🔥

3/?
DERRY:
They left.
They threw me off the wall.
🔥[[CRACK!]]🔥 Just like that...

>The hay rustles. His body twitches with each flicker.

So now I sit here. Hollow.
Not bright enough. Not full enough.
Not scary enough.
Not 🔥ENOUGH.🔥

But you...
you’ve still got your LIGHT.

2/?
DERRY:
... I have one too, y'know...
A little 🔥flicker-🔥flicker-🔥flicker—
trying so hard not to go out...

But yours...
Yours still shines.

>The candle grows stronger, then sputters again.

That dark, dark NIGHT...
🔥THAT KNIGHT.🔥
They picked us... shaped us... lit us up like STARS.

And then?

Derry, a 🧵

DERRY:
...h-h-huh?
Someone there?

>A face glows faintly, carved into a permanent jagged smile.

DERRY:
A visitor? Little Patch? Big Jack?? ...No.
No... you’re like me, 🔥aren’t you?
You’ve got a light... inside.🔥

>a flicker. the smile trembles and fades away, like wax melting too fast.
