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.

Summary
After leaving the underground, monsters and humans are finally at peace...or it would seem so, as conflicts arise: Will everyone be able to overcome past conflicts and move to the future, or will they divide once more? It's up to Frisk, who is perfectly fine and is totally not going through an identity crisis that is totally NOT your fault, to solve!

A FINE LINE BETWEEN ORANGE AND YELLOW by MairwynCSulien1990

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
Two souls in the Underground, intertwined by fate and by a prophecy that keeps them apart.
Heads up before you read:
In this fic, Chara is alive and far from a good person. They’re not a mindless killer, but a narcissistic kid. This is not a fluffy Charisk story. Chara and Frisk’s relationship is deeply toxic.Please look at the tags before you continue.
I've been experimenting with third person for a while now, and I've grown to like it a lot more than first person. For those who came from my other fic, which I promised a sequel for, I’ll try my best, but I’m not sure how that will go now that I’ve fallen in love with third person and started a new long fic. Please don’t be angry I will try to finish my other fic as well.

Summary
This the story of Kingdomtale, an au I created that's essentially Undertale if it took place in the medieval century. It's not historically accurate but it's my take on this popular concept. I have already posted a series for this au but have grown dissatisfied with it. I know I can write something better. This is the new and improved Kingdomtale, and it's going to come back even stronger and better than before. My hope is that this story can feel nostalgic in a way, like you are experiencing Undertale all over again for the first time.
Here is just a quick snippet of the plot: The year is 15XX, and another human has fallen down Mount Ebott. This human is no more than a child, having woken up in a bed of golden flowers. How did they get there? They'll soon discover a world of monsters, magic, and much more. Can one human child bring peace between two different races that have been forced to share one Kingdom? Well, you'll just have to read to see if the story is still as you remember it.

Soul of the Heroes by AmityBlight953

Summary
“What’s your name?” Wind asked the kid.
“Link….” He responded in uncertainty.
“Well Link, this might sound a little crazy, but we’re all Links too.” Time said.Basically I add my own Link to the Chain, but instead of making up a journey for him I’m using Undertale as his journey. I also made up a few journeys for him, but his first and main one was Undertale……
Warning if you haven’t played Undertale this contains some spoilers for it. It’ll mostly be pacifist route spoilers, but there will be a few from some other routes.
