A series of small stories attached to a few different skeletons. Some are a few chapters, some are one-shots. A companion compilation to "Reset," meant to add a few explanations, flesh out some details, and play with some post-Pacifist-Ending ideas.

A human fell into the Underground, and began befriending every monster they came across, including the skeleton brothers. Their acts of kindness seemed to be genuine, giving the monsters no reason to distrust them... Until the human pulled a one-eighty and killed Sans when everyone least expected it. This is the story of how Papyrus grieved over his older brother's death, how he discovered the truth about his mysterious sibling... and eventually, how he decides to avenge his sibling's murder. But in the end he'll forget everything once the timeline resets again, right? That's what he's afraid of. (Based on the AU "Disbelief Papyrus," but with an original twist. There are no pairings except for what's canon. This is mainly Papyrus-centric, but it does focus on mystery of Sans during the story.)

**ON HIATUS** "The game is yours now." ~~~~~~~~~~~~~~~~~~~~~ Many have heard the story of Chara, the first fallen human, but none know the truth behind it, or the story that follows. In another timeline, in a world where anything's possible, so long as the puppet master pulls the correct strings, we can learn about who this fallen child is and how they can change an entire game. ~~~~~~~~~~~~~~~~~~~~~~ When Frisk, a human from the surface world, fell down into the Underground, they had no idea what they were getting themself into. Chara, the first fallen human, had returned from the dead. Now Chara, filled with hatred at humans, roams the Underground gaining LV and EXP by killing monsters, with hopes to erase all of humanity from existence. Can Frisk manage to return to the surface and save the Underground? Or will Chara successfully receive the vengeance they wish upon humanity? (Cover art is not mine.)

A•pa•thy /adjective/ lack of feeling, emotion, interest, and concern. ~~~ I wake up and I go to work. I see faces, and I instantly forget them. Everyday, the same thing happens. Today, however, I see someone rush to a room, then more people. Then I hear screams. Then the police are here, asking me questions. I might have just witnessed a murder, but my lack of caring caused me to forget every important thing.

What happens when a human gets tired of resets? When the thrill of a genocide route becomes boring and mundane? This is exactly what happens to Frisk. They spent so much time going through reset after reset that now they are growing tired of it. However, little do they know that their next timeline will be one of the most interesting they've ever had. When Frisk resets after an incomplete genocide, it captures the attention of a certain alien Timelord called The Doctor. He has to travel between dimensions to investigate this strange anomaly, but ends up with an adventure much more strange than he had initially anticipated. This timeline is breaking. The entire reality is being torn apart and it's up to Frisk, Sans, and The Doctor to stop it. (Disclaimer: I do not own Doctor Who or Undertale. The only thing I own is the plot line and the writing.) Cover art by @GodOfChaos3900
