Summary
Error wakes up in a game he never chose to play—Until The Last Breath, a brutal survival world hidden between life and death. The only players? People trapped in comas. The only way out? Win.
To survive, he must fight through deadly floors, forge uneasy alliances, and follow three unbreakable rules:
[ 1. GAME OVER means death, both in-game and in real life. ]
[ 2. Artifacts must be crafted from Fragments found throughout the world by a Player. ]
[ 3. Reach the final floor before the chronometer runs out… or fade away forever. ]
There are no second chances. No resets. Just one question: can Error and his team beat the game before it beats them—and can love survive in a world designed to tear everything away?

Summary
A brother adored, a brother scorned. The choices made by the masses that led to a war. A kingdom divided and the middle ground neither can claim. A past that should have been long dead resurfaces- and it changes things. The sun and the moon shine brightly- but what about the beauty of the stars?
Or; Nightmare and Dream are at war, and their friends have to deal with it. A part of the past the twins- especially Nightmare- have thrown away comes back. Things change; but is it for the better?

Summary
We're back with another year of Inkwhumptobertale!
And this year, we have another twist: another list! That's right: every day, I'll be facing the challenge of eight different unrelated prompts, and I'll have to do my best to cram them all into the story, somehow. Admittedly, there is a low chance of me actually doing that, but I am obligated to use at least three prompts each day, and I'll add more if possible. I'd like to do at least one day fitting all eight prompts into the story at some point in the month, though. So..prepare for chaos!
These characters are not mine!

Summary
Here we are again! Another series of Undertale one-shots following the Fictober prompts and featuring the skeleton brothers as love interests to either my nameless or named girlies.
Just like the past two years, if you'd like any of these to be turned into fics, then please let me know in the comments! If enough people show they're interested, then it'll be added to my list of future fanfics! Five requests are what's needed for them to be added.
And if you choose to wait till the end of the month to read, that's okay! Requests can be made up until November 7th, when I post the list of the lucky winners!
Hope you all enjoy!
