    Summary

    It's been a year and four months since the Barrier was broken for good and all Resets have come to an end. Life has been far better than anyone could have hoped for! Everyone is doing their own thing and living their best lives. Sans and Toriel have even become the parental caretakers of Frisk, Chara and Asriel. At long last, the nightmare is over.

    ...

    Unfortunately, one cannot escape their past. Sooner or later everything has to come out. The children and their genocidal past, Resets, Asgore's mishandling of the Underground...

    Then, there's Sans. A skeleton with many secrets. He's not doing so well. One could say he's the DEATH of the party. Fortunately, a certain skeleton outside of space and time knows what to do.

    "If you want to save Sans, all of you must be willing to pay the mental and emotional cost."

    In order to keep Sans alive, those closest to him must learn his secrets.

To counter this, the government issued a new project called the Dreamcatchers. Small shops will sell special dreamcatchers that contains a guardian, it is said that these guardians will protect you from nightmares and night terrors.

    Summary

    Quantas vezes você precisa apertar um botão repetidas vezes para que ele finalmente ceda ao uso? Quantas vezes se deve repetir um mesmo momento até que alguma coisa mude? Você teria que pagar algum preço por seus pecados ou ao voltar no tempo eles simplesmente são apagados, mesmo que permaneçam em sua memória?

    Não importa o mundo, não importa o tempo, não importa quantas vezes se repitam, algumas coisas nunca mudam. Mas o tempo espaço não pode ser tão resistente ao ponto de aguentar constantes instabilidades fluindo por suas cortas. Em algum momento alguma coisa tem que quebrar e o mundo deve vir a baixo.

    Frisk não sabia, ou ela tentava não saber, que todos os resets que ela e Chara estavam a cometer enquanto disputavam pelo controle poderiam gerar tal caos ao ponto de fundir todas as dimensões em uma única. E para o desespero de Frisk isso não significava que os resets haviam terminado e que poderia alcançar seu final feliz. Isso apenas queria dizer que agora ela estava sozinha com as lembranças de cada dimensão, de cada diferente Frisk, de cada linha do tempo... Enquanto desesperadamente implorava para que tudo simplesmente terminasse e não apenas permanecesse um ciclo sem fim de acontecimentos iguais.

    Summary

    "Have you heard? The old Script farmstead finally got bought!"

    "Really? It's about time! I thought those three would never agree on what to do with that old place and it would eventually get split among even more heirs until it went to ruination."

    "Oh yes, Verdana heard it from Arial who heard it from Oswald that Courier saw a group of skeletons ride into town and go straight to town hall to arrange purchasing the whole farmstead."

    "I wonder if they already know someone in the area, seeing as they knew there was even a place to buy and just how to get it. I can't see anyone getting those three old codgers to agree to anything without some kind of warning."

    "Most likely, I'm just excited about having some new neighbors. If they know someone already all the better, whoever they know can make introductions."

    "That would make things simpler, let's ask around and find out."

    "Great idea, let's!"
