Summary
Ten years.
Clover has been trapped in a loop of running through all the different routes of Undertale Yellow for ten real-time years.
Then, during one of the thousands of hateful massacres that have played out, something changes.
Right at the end of the bloodsoaked path, unable to suppress a guilt gnawing at them from within, Clover turns their gun on the yellow flower a touch early.
The gunslinger fights Flowey with an equal level of Determination. The save file is damaged in the crossfire, and the save system is destroyed.The data corruption sends Clover through the void, all the way back to just outside Mt. Ebott, and also ages the gunslinger as well as the world itself by ten years.
While in the void, he sees fragments of events in the other routes, and a vision of a person he's never met before trapped in a certain laboratory.Burdened by the weight of his sins from his last journey, and armed with a vastly more mature body and mind, the fully grown cowboy decides he has to do things differently this time.
No more SAVEs. No more LOADs. No more RESETs.
All actions have permanent, irreversible consequences.
This is their final shot.
Do or die. -

Diving for Justice, Freedom and Managed Democracy by Dangeresque_On_Ice

Summary
The Monsters were dead.
They must have been, the Federation of Super Earth had said so; annihilated during the Great Galactic War along with all the other threats to Managed Democracy. So Clover was understandably confused when he set out to find the five missing Cadets only to discover a whole society of Monsters sealed underground.
What’s more, these Monsters were nothing like the tyrannical, Freedom-hating killers history had portrayed them as.
Things just weren't adding up. But why? It’s not like Super Earth would have lied, right?

The Weight of Acquittal by Your_Resident_Liability

Summary
Clover's Journey has come to its end.
For most of the Underground, this is a cause for celebration. After all, monsterkind is now only one soul away, and most can live knowing that they will likely be among those who will first step onto freer soil.
A select few, however, see things differently. For them, that human's death provides only unanswerable questions, not peace of mind.How can they honor the memory of such a beautiful yet fleeting life?
How do they go back to living normally after having their previous lives shattered? Is it even right to try and 'go back', or should the pieces be formed into something new?
'Right' and 'wrong' have been revealed to them, but can those things still be found once the light of justice fades?
Creating new light is not so easy. After all:
Sparks cannot be captured
The sun doesn't reach all corners
Stars don't always shine brightly enough
And not all flames can be containedBut perhaps, as the sun gives way to stars and artificial light, so too can the many guide one another along each leg of the journey. They just need to find each other first.
