Summary
When your life comes crashing down at a young age, some screws and more are definitely going to come loose and jumbled up. You can't remember what happened. Or, rather; you don't want to.
You couldn't do anything about it, couldn't control it.
And yet, you're burdened nightly. Burdened in your moments most isolated, by a voice that insists upon the notion that you could have done more. That you could have prevented something from happening. That pushing forward is for naught.
No matter how far you go in life, it will burden you unto eternity. That, is what you tell yourself anyways. However, perhaps...
Perhaps that will change. You've opened up a little more, shied away less from visages unfamiliar to you. And now? Maybe now, you can find something that'll pull you out from this dark haze.
Maybe even someone.
...You hope someone will.

Summary
In Woventale, the Underground is a patchwork of strange cities and altered destinies, where familiar faces walk unfamiliar paths. Across the stitched landscapes of Snowfall, Sea Shore, Smokestack, and the Forest Ruins, lives intersect in quiet, calm, or sometimes dangerous, and unexpected ways.
This is the world woven by 'Watchers'. Like you. So why not stay awhile, and listen?
This - is not a grand story. This is a collection of short stories, moments, scenes and encounters.

Summary
Technology is a fascinating thing, and you had always wanted to use it to help humanity. Unfortunately, you live in the age of late stage capitalization and AI bullshit. You've been working as an alpha tester for a VR company for a few years, but after they started up a new AI branch you've been force to pivot towards testing that instead of the usual physics emulation. It's something that should be given to a psychologist, but you really can't afford to fight for another assignment. Just push all your ethical protests to the side and get the work done. It's not like your whining will change how silicon valley is doing a dystopia any% speedrun right now.
And most importantly, remember that nothing you make will ever actually care about you.

The story officially begins when Toriel dies in her universe mysteriously. Gaster with his allies show up and take her soul remains back to his lab to save her life. Toriel then had DETERMINATION injected into her. Most of the DETERMINATION was collected from humans in multiple different universes. Gaster created the perfect solution to end RESETs and genocide routes that plague The Multiverse. A new kind of boss monster with the ability to utilize the power of the savestar. Toriel, who got reborn as Gaster's daughter in his lab due to a serious situation that happened, it was the only way to save her life.
Gaster embarks on his quest to bring peace and balance to The Multiverse. However The Savestar becomes corrupt, doing more than its intended function.
If the RESET function is over-worked, it will erase a universe. The more universes that are gone, the more The Multiverse dies. They explore every universe they're able to, attempting to fix the savestar and rid the ability to RESET, helping others and themselves.
Note: The AU is heavily in progress, unsure when new content will be published. Hope you enjoy what exists right now though.

Summary
Player on their third playthrough and save file of chapter five manages to convince Gaster to go on a date with them to "show what a first date should be like." After Kris' and Susie's dates fall apart, Kris pulls the Soul out and throws them into a box to create the next Dark Fountain. Player and Gaster get some much-needed bonding and time spent together, with the looming threat of the plot chasing them behind.
Well, more like everyone desperately needs Player to go back to being a heart and Gaster to go back to the void, so everyone can actually have a winning chance and the plot to progress.
