A long time ago, monsters and humans lived peacefully. Then, war broke out.
The monsters were forced underground, and the humans were left above.
A killing machine was created, to destroy all the monsters in the underground.
This is her story.
Asgore is the prince, who lives in the palace with his father (Nazur) - who is on the edge of death - and his wife (Toriel) and son, Asriel. Toriel and Asgore are about 20. Gaster and Grillby are buddies around 19. Sans and Papyrus have no set age, they're experiments. If they did, they would be 17 or 18.

(Sans x Reader) When Two Souls Meet
Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister.Complete
All I want for Christmas
Our beloved Monsters live at the surface for almost a year now. As Christmas time begins, they are all overwhelmed by the festivity and happiness this time of the year brings to everyone. And monsters realize: it's been a long time since they celebrated a family festival under the stars. This is basically a small collection of one-shots that play in the same universe. It will work like an Advent calendar, which means there will (hopefully) be one chapter per day , until it's Christmas eve. Please understand that I am not a native English speaker, so if you find any grammatical errors or typos just point them out to me. I will gladly correct them and learn for the future.Complete
Gaster x Reader
Pretty self explanatory. This takes place after the Pacifist route in Undertale. Through determination, Frisk was able to bring back Chara, Asriel (Asriel is Flowey per say), and Gaster. I believe that Gaster is the father of Sans and Papyrus. I also don't believe that Chara is evil. The monsters are on the surface, and although they are amongst humans, most humans have accepted them.Complete
Dusted hands
Gaster couldn't help but think of the good times knowing that soon those memories would perish in this war along with many other monsters and humans. Gaster and Grillby had to lead their army to a victory, to defy humans even if their last breaths were spitting on the humans shoes, "Now isn't the time to sit and lick our wounds, monster kind depends on us and if you think siting here and sulking is going to help win the war I have to disagree with you." -Gaster.

From Darkness, Love Came Through
A long KingDings fic because this ship does not get the attention I think it deserves. I love this ship, and it's adorable. I plan on making this a full story, so buckle up! Also in this Gaster is Sans and Papyrus's father because Dadster is wholesome and cute. Toriel and Asgore are decent friends in this one because I believe that they could have a friendship if they tried. I will put in little bits of my other ships, but Asgore and Gaster are the main focus. If you want the actual story, read it. It's very fluffy and cute and gay. If you follow me, I know you like the gay ships.Complete

Roommates (Sansgore)
(Toby Fox owns UnderTale, I plan to replace the cover with my own, and there needs to be more Sansgore like what the actual heck) After the surface was finally in the monsters grasps, they were so excited to move on and find new lives under the sun. However, Papyrus wants Sans to move on and get his own life and house. When Sans sees that Asgore too has no plans for the surface, he offers that they could be roommates in this small house. Asgore agrees. They're totally not gay for each other.Complete
