Summary
In 2015, Toby Fox discovered the Multiverse. By 2040, mankind reveres the AU characters, treating most like celebrities and some like gods. Naturally, unethical experiments ensue, and some humans are turned into powerful monsters for the sake of researching without disrupting timelines. They may fight to stop the cycle, but some will not come out the same as they once were.
This work was remade in protest against current censorship laws around the world after the deletion of the original copy of SDAU off of Google Docs.
NEW FEATURES:
-New content and lore
-Improved writing
-Third-person perspective for ease of POV changes
-Unabashed Dreammare subplot
-Trans plotlines for Lamia and Scarlet; otherkin plotlines for Wren and Adwin
-The villains are worse somehow
-Nearly everything has been rewritten! -

Summary
The Barrier is down, monsters are walking the streets, and reality just got a lot stranger.
Rhea is human, unprepared, and stuck in a house full of wildly different, unpredictable skeletons. Some are warm, some dangerous, all impossible to ignore. Pulled through by a mysterious machine, she’s trapped under their watchful eyes while the multiverse starts leaking into her life.
Rhea navigates the household of chaotic, flirtatious, and often deadly skeletons, while trying to come to terms with her new fantastical, but very real reality.
Darkly funny, magically strange, and dangerously charming. An urban fantasy reverse-harem story about survival, trust, and learning to live among the bones. -

Summary
Months after being on the run, I was finally found and made to stay with a mage. Unfortunately for me, the mage I was stuck with was more evil witch than mage. Not only that, but he's caused the many skeletons that lived on his property to dislike me, too.
As grim as it was, I could manage. At least it was better than death.One month into my stay, however, something changed. Another skeleton appears, one much different than the pairs that the other ten came in. The mage demands that this skeleton be roomed with me in the attic. The attic where all the rest of the forgotten things go.
The rest of the skeletons argue and attempt to find compromise. During all of this, though, this new skeleton meets me.
And he refuses to leave me alone.- Language:

Summary
Шла, шла и умерла. Мало того, что умерла как лох, так ещё и после смерти покоя нет. Без моего согласия запихнули в глючную задницу всего мультиверса! Мою любимую Ошибку, конечно, но всё же! Не хочу быть разрушителем вселенных. Работа эта неблагодарная, опасная. Так ещё и без зарплаты и отпуска. Идите все нафиг, я сбегаю. Пусть в этой мультивселенной хоть коллапс произойдёт от переизбытка мусорных вселенных! Мне плевать!

Summary
With the ascension of monsters, there hasn't been a boring day since. Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I lived in starts getting new residents.
The only problem now is finding a better job.
Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept.
And I soon run into a whole bunch of other skeletons that all seem to like me.
Romantically, and I'm afraid of what will happen. -

Summary
Finding yourself in a whole different multiverse wasn't exactly how you were planning your week to go, but knowing you, it was bound to happen at some point.
But hey! It's not all that bad.. well except for Dreamtale being in utter chaos, not having the squad with you, and being 'kidnapped' a couple times. But then again, this multiverse was already proving to be much better than your previous one. Or at least, there is more opportunities here. And come on, how could you miss the chance to see this many stars?!
Now you just needed to figure out how to get the squad here, hopefully without the stupid chicken.
Nightmare has a bad feeling, your Nightmare. You'll just have to make sure he doesn't go insane with worry.
