WHY ARE THEY STAYING OVER TOO.

Summary
"A long, long time ago, another human fell down here."
"Injured by their fall, they cried out for help."
"...But nobody came."
Or
Chara didn't wait as long for help, and by the time Asriel works up the courage to investigate the cry, they're already gone. The butterfly effect (and the addition of a bunch of my headcanons and ideas) does the rest.

Summary
Fighting against royal nepotism,
Stood 4 humans who died for monsterkind.The first was the patient of spoiledness,
Who planted the seeds for action.
Then came the revolutionary,
The brave soul who died for the cause.
Don’t forget the human who stood on their values,
Whose silent perseverance was idolized for resilience.
At last was the giver,
Their kindness to the unkind led to their demise.The fifth, the enforcer of justice.
With the revolutionary seeds in the soil,
Born with a soul so determined,
The others sat for him so he could stand.
---
A world where Chara and Asriel weren’t able to go through with their plans, yet the royal family continued on a murder spree. For each human who fell, the underground saw them as leaders of revolution, only for that hope to be stripped by the monarchy. How would Clover be different from the others?Navigating through the complex relationship between the crown and the underground, Clover and Frisk set on a journey to liberate monsterkind, using everything they could to bring justice against royalty. But when one man serves as the judge, jury, and executioner, how fair can justice really be?

Summary
Another SOUL is added to the collected collection of many more; the monsters rejoice in their progression to freedom. But only a handful know of the tragedy behind their success, mourning the loss of a life that's already deemed forgotten.
They don't even know the child's name, do they?Only until then, Monsterkind remains and waits for the last SOUL to be collected, questioning and guessing how time will pass until their freedom is within reach.
They come with their name being 'Frisk'. The last human to fall, and the one to rekindle their hope.
An AU "what-if" scenario where Frisk spends a little more time in the Underground during a True-Pacifist Route, or on-route towards one.
Some Monsters just can't help but gossip about humans, can they? And it seems the ones in Hotland like to chat about a specific human in an area Frisk has yet to see.

Summary
Clover is dead.
And yet, he persists.
Unable to let himself fall into the unknown that is death, his soul clings to a facsimile of life, trapped in darkness with nothing but his thoughts and time to reflect and ponder. He will not, cannot move on, even when there is nothing left for him in this world. No body, and no hope of returning home. No hope of reuniting with his friends.
Until someone called for help.
Now stuck in an Underground he does not recognize with only his trusty four-shooter and a friend he can’t trust, Clover searches for his friends, the voice who called for help, and answers. Retracing his path through the Underground, and forging a few new ones as well, Clover battles his thoughts, suspicions, and memories of events that never occurred, but won’t quite leave him either.
Now, if only he could find his hat.
