Summary
You're pathetic
Rotting beneath trash, worthless.
You're alone
Inconsequential. Useless.
Stop
Do you here that?
Running water.
Go down.
You shouldn't be here.
Disclaimer to anyone reading: This is an old fic, it is currently being re-written to portray the heavy topics I initially attempted to include in a much better way. This fanfic is not a portrayal of my moral, beliefs and or character, I'll be doing my best to edit out any weird shit 16 year old me wrote on a wim.
The writing isn't shit, it just makes me cringe to think about it...definitely not my best work
Also, in the re-write I do plan on NOT ruining G/Echotale, I don't know why I did, I'm also working on something to un-Frans(eugh) his au.(8/27/25) Papa's back and actually editing/writing!?!?!? Who woulda guessed. I'll be doing it in small sections (or big). I label the unedited chapters later.
I was hit with motivation at this fine hourI'll try to stop being schizo in the tags lmao/ I'll change em' later

A FINE LINE BETWEEN ORANGE AND YELLOW by Fantasy_Artist
Fandoms: Undertale (Video Game), Original Work
09 Oct 2025
Tags
Summary
While Aneira didn't necessarily believe monsters existed, she did find the fact that everyone and their dog still did might mean something. Her childhood town of Beddgelert believed in monsters trapped under the mountains near their home that would need a seventh soul now to break out and destroy lands.
Aneira also knew that she needed to figure out what happened to the kid she was friends with who went missing. Which was how she found herself having fallen (probably) hundreds of meters below a mountain inside a cave system. Was she stupid for leaving without telling people where she was going, definitely, but, to be fair, she didn't expect to fall; she couldn't even see the hole.
Injured and wanting to go home, Aneira braves through the underground cave systems, finding MONSTERS both friendly and foes, learning about what happened to all the previous (children) HUMANS that fell.
tldr: Aneira falls instead of Frisk, is injured and is too stubborn not to use this chance to find out what happened to a friend (definitely dead by now, but she still wants to confirm), the Undertale cast feels like something is different, but not what. They also live in Wales here because why not?

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.
