Summary
Dust has always been obsessed with ghosts, the paranormal, and all things supernatural. Most people think his fascination is weird, even his friend Blue doesn’t believe in ghosts. Determined to prove him wrong, Dust takes matters into his own hands.
Killer, on the other hand, is an urban explorer who documents abandoned places through videos and photography. When their paths cross, the two end up in a bizarre encounter that goes viral overnight.
Now, the internet has dubbed them the next big paranormal investigators, and everyone’s demanding more. The only problem? They have no idea what they're doing.

Summary
VERSIÓN EN ESPAÑOL
Hay muchas maneras de dañar una relación... para los enamorados, podrian ser por mentiras e infidelidades. Para las familiares/ hermandad también podrían ser a bases de mentiras y engaños, pero sobre todo... falta de comunicación. Es en base a esto, la relación entre Nightmare (antes conocido como Moonlight) y Dream se desmorona, y todo empeora cuando su madre solo decide llevarse a Nightmare a vivir con ella. Tal vez, en unos años, ambos se reencuentren y puedan volver a algo parecido a lo que eran antes...
pero...
¿Lo conseguirán? ¿O terminarán rindiendose y se separarán de nuevo?

Summary
[This is a companion fic to "Somebody That I Used to Know"]
Ccino’s life had been mediocre at best. He’d run the coffee shop, a hot spot for those travelling the aware universes that littered the multiverse. It was marked down as a neutral AU, the inhabitant having signed a contract with the Omega Timeline to remain as such in the various spars between the twin guardians for the upperhand in the balance of emotion. Anyone was welcome, whether you were directly affiliated with the Omega Timeline or were under Nightmare’s foot, clawing to be free from its oppressing debt of ‘kindness.’ As far as Ccino had been concerned, the AU and the coffee shop it resided in were neutral; his own feelings on the matter weren't.
-----+-----
When Ccino disappears, who's left to take care of the shop? To feed the cats? To continue his legacy?
Fortunately or unfortunately, Nightmare is there to take up the mantle. Its grief refuses to cooperate.
But why does it feel such intense grief? Is there something deep inside that it hasn't realized yet? What of the Omega Timeline and its council?
Will it abide by the contract of neutrality?

Summary
“You want to break up the Star Sanses?” Blue repeated what Dream had said in shock, standing up from his seat suddenly as if he wanted to argue with him, “Dream, this isn’t a good idea! You can’t fight Nightmare alone, he’ll destroy you. There’s too much negativity, you said so yourself yesterday, and it makes you weak..."
-----+-----
Ink had done it for the last time. Dream couldn’t stand him sacrificing so many people to save the AUs that made up the multiverse, he couldn’t stand Ink making the Star Sanses be seen in such a bad light that Dream was getting sent death threats. So he broke the group up, even with Blue’s protests and Ink’s surprise. The Star Sanses didn’t exist anymore. He wasn’t Ink’s friend anymore. Blue couldn’t multiversal travel anymore, stuck in the Omega Timeline since he couldn’t go back to his AU. Dream didn’t have people to back him up anymore. And with no group seemingly able to stop people who meant harm and protect AUs anymore… There was a spike in destruction and negativity. The negativity was because of Nightmare, but what was destroying harmless AUs? That was what Dream was going to figure out. Who knew he’d meet someone special to him in the process?

Summary
VERSIÓN EN ESPAÑOL
Ya han pasado 400 años desde que Dream empezó esta batalla contra su hermano y no ha progresado casi nada en devolver el balance al multiverso. Poco a poco siente que se está desgastando física y emocionalmente, necesita un descanso, pero no puede detenerse ¿y cómo podría?, ahora mismo trabaja casi 24/7 y no ha avanzado casi nada ¿Cómo podría siquiera pensar en dejar desprotegido a todos los Au's que le han suplicado que los ayude?. Pero claro, el cuerpo en ocasiones es traicionero, y Dream no es la excepción a eso.

Summary
ENGLISH VERSION
It has been a week since Dream returned to normal. Nim explicitly told them not to disturb him due to his physical condition, but Nightmare and Moonlight needed answers. How did Dream access the powers of a negative apple? It wasn’t possible that Dream ate one; they remember a fight where he had one in his hand, it fell, and when his brother touched it, he turned it into a positive one. So… how was it possible for Dream to transform into Shattered?
I really like the character of Shattered, but I don’t like how it was created. So I thought, "Why not make my own version?"
Shattered does NOT have tentacles like Nightmare, but wings like DS Dream.
Moonlight and Nightmare are similar to Eddi and Venom... in terms of the transformation.
This story takes place in the Omega timeline.
I used Chat GPT to translate this, let me know if there is any mistake.

Summary
ENGLISH VERSION
There are many ways to damage a relationship... for lovers, it could be through lies and infidelities. For the family/siblings they could also be based on lies and deception, but above all... m̶i̶s̶u̶n̶d̶e̶r̶s̶t̶a̶n̶d̶i̶n̶g̶s̶. It is based on this type that the relationship between Nightmare (formerly known as Moonlight) and Dream falls apart, and everything worsens when her mother only decides to take Nightmare to live with her. Maybe, in a few years, both of them will meet again and can return to something similar to what they were before... but...
Will they get it? Or will they end up giving up and breaking up again?
This fic is translated thanks to Google Translator, so some parts may not be completely understood...
If you speak Spanish, there is a version in that language on my profile
I’m not going to finish this until the Spanish version is completely released
