This is rushed. Had an idea and jotted it down as fast as I can.

Dream slinked in the pillar shadows of a glorious judgement hall.

Ink, Classic, and Fell stayed close behind him.

The creator placed a hand on his shoulder.

"How long?"

Dream hummed. "A minute or so. My brothers aura is close."

Ink nodded and turned to the other two. "The moment he strikes the statue we attack."

Fell scowled in anger. "I can't believe these bastards are going to damage such a sacred monument." Classic nodded in agreement.

The Au they stood in was an ancient one. One of the few remaining originals.

The monsters had long sense left. All that remains is the ruins of the underground. The only surviving structure is the judgement hall.

Inside is a two story marble statue of Dike, the Greek goddess of justice, the spirit of moral order, and fair judgement; standing almost untouched by time.

A sacred symbol to all Aus who regularly come to pray to her.

Dream had felt the Dark Sanses roaming the world.

He knew they were after the statue.

Her destruction would cause a tidal wave of despair and negativity. It was the perfect opportunity.

Dream perked up at the sound of footsteps on tile. He lowered his aura, hoping the other wouldn't sense him.

His allies felt the drop and hid themselves better. Glaring at who had arrived.

Stepping from the shadows was the King of Darkness himself, Nightmare.

His tentacles waving slowly, eyes fixed on the large statue before him.

He stepped forward slowly.

The four heroes readied themselves.

Dream summoned his bow ready to strike when he noticed the others tendrils retreating into his back, a soft hum coming from him.

The other stepped closer. A few feet away, and began to do something that stunned the four.

The God of negativity began to sing.

His voice deep and sorrowful that echoed through the hall.

"I don't know if You can hear me....
Or if You're even there,"

He looked to the ground, eyes dull.
"I don't know if you would listen, to a bad guys prayer,"

He clinched his fist. Eyes shutting.
"Yes, I know I'm just an outcast.
I shouldn't speak to You,"

He lifted his head to meet the statues eyes.
"Still I see Your face and wonder.
Were You once an outcast too?"

Nightmare stepped closer, the four snapped out of their shock. Ink stood, ready to strike but Dream held out an arm to stop him.

The god of negativity continued to sing out.
"God help the outcasts,
Hungry from birth,
Show them the mercy,
They don't find on earth."

The gang stepped out of the shadows one by one. Eye full of sadness as the look to their leader.

Nightmare glanced at them softly.
"God help my people
We look to You still
God help the outcasts
Where nobody will..."

Killer stepped up.
"I ask for health,"

Dust stepped up as well, placing a hand on Killers shoulder.
"I ask to end this game,"

They harmonized together.
"I ask for you to end our pain!"

Horror gently grabbed Dust hand.
"I ask for love-"
Dust began to sing along.
"-I can possess,"

Cross and Killer joined them.
"I ask for you and the gods to spare us!"

Nightmare, through this all, began to change.

The toxic sludge around him began melting away.

Dream held in a gasp as Nightmares older form, the one the thought he had lost forever, stood in place.

Nightmare balled his fist a few tears dripping from his cheeks. He looked up at the statue. Almost pleading.
"I ask for nothing!
I can get by!"

He gazed to his boys.
"But I know so many.
Less lucky than I."

His eye shot back to the statue as he kneeled before it.
"Please help my people!
The poor and downtrod."

The gang slowly kneeled down around him.
"I thought we all were.....
Children of the gods..."

Killer embraced him from behind, the others joining in as Nightmare sang out one last line in a cracked, sorrowful voice.
"God help the outcasts......
Children of the gods...."

Ink, Classic, and Fell stood behind the pillars, tears pricking their eyes.

It seemed like they only wanted their suffering to end. This whole time, had they been wrongfully judging them?

Dream seemed to be taking it the worst, holding back sobs as he watched his brother, in the form he knew and loved, break down and cry.

This whole time he believed Nightmare had stolen his brother away. Killed him in a way. A reason he felt little remorse for fighting him.

But he was wrong. So, so wrong. Nightmare didn't take Nighty away.

Nightmare was Nighty.
