Summary
A day has passed since Tenna settled into life with Mettaton- watched and appreciated, he's very hesitantly happy with this new, shaky life.
That is, until two certain kids get a little too curious, making the Knight have to set an example- or, perhaps, cause a distraction?
Originally a supposed murder attempt, Tenna can now walk around in the Light World, able to switch between ordinary TV and monster. Now he has to actually put the work into acting like a person, sorting through his trauma, and getting to know his new roommate. When characters from his past start making things more complicated, will he be able to handle the pressure? Or will he shatter for a third time?

Summary
Tenna considers himself to be a seasoned family entertainer, a jack of all trades in the high-flying business of distraction. He knows what makes children laugh and mothers smile.
His new home has no children or parents. It’s barely a home at all, only a tiny room with an audience of one who is neither mother, father, nor child.

Summary
“Goodbye,” I whispered, with a small wave.
Seeing her standing there, her hands clasped in front of her, shedding silent tears, made me want to turn back, made me want to make it okay, but I couldn’t. I had to grow up. I had to move on.
I turned and pushed open the heavy doors. There was a ramp, leading upwards, towards another set of beautiful columns. I took a deep breath and pushed forward.
Step by step, I made it to the next set of columns.
It was dark.
Here goes nothing.
I took the final step out of the Ruins, and my foot crunched on something white and cold.
“Oh, come on!” I shouted at no one.
I hated snow more than anything in the world.

Summary
Telila had never really did anything remarkable as a scientist and she knew it, she wanted to be seen as a one and not just the coworker of alphys and gaster. She had been trying to be more useful to society in the underground by fixing more stuff, discovering new stuff or even making new things. But the underground had a bigger concern, the barrier. She noticed that her efforts were less and less acknowledged, that her friend Gaster acted distant and that the king seemed more distracted... Then a question appeared in her head, it lingered and made it almost impossible for Telila to think about something else: could she make a nonhuman soul strong enough to break the barrier? After a few tests and studies she came to the conclusion that she could, by taking any kind of fragment of a soul and fuze it with another weaker soul and in this case an animal soul's, it would make it strong enough to count as another human soul and break the barrier. she didn't want to take the soul of another monster to strengthen the weaker soul and she didn't want to take only hers either, it could harm or even worse, shatter the soul of the monster. But with a little help from one of the human soul she wouldn't even have to sacrifice her soul.

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
A long time ago, two races ruled over earth. Humans and Monsters... but that's a story everyone has heard before. The laws have been changed, fates had been broken, chains had been mixed, concepts and reality itself had been shattered against their will, and reborn into something that shouldn't be possible for the Underverse's standards.
"My Child. You've gotten an invitation."
"Hm?... Chaldea? What's this about?"
Frisk looked up at his mother with intrigue, his eyelids opening up slightly, the soul of determination sat on his chair, looking at the letter that had just arrived, before the former Queen of Monsterkind took her phone, contacting her ex-husband and the rest of her friends for some advice. For some reason... not just her, but Frisk as well had a bad feeling.
A very... very bad feeling.

Summary
Hace mucho tiempo, dos razas gobernaban la tierra. Humanos y Monstruos... pero esa es una historia que ya todos conocen. Las leyes habían cambiado, destinos fueron rotos, cadenas entremezcladas, conceptos y la misma realidad fueron hechos pedazos contra su voluntad, reformados en algo que no debería de ser posible para los estándares del Underverso.
"Mi niño. Has recibido una carta."
"¿Hm?... ¿Chaldea? ¿Pero esto qué rayos es?"
Frisk miró a su madre con intriga, sus párpados abriéndose levemente, el alma de Determinación se sentó en la silla, mirando a la carta que acababa de recibir, para que luego la antigua Reina de los monstruos agarrase su teléfono, contactando a su ex-esposo, y al resto de sus amigos en busca de su concejo. Por algún motivo... no solo ella, sino que el propio Frisk, tenían un mal presentimiento.
Un muy... muy mal presentimiento.
