Summary
Please note: English is not my first language. Thanks for understanding.
In a multiverse built on creation and destruction, timelines flow according to unchangeable laws. As resets repeat, 'anomalies' begin to appear, threatening the very existence of AUs. Ink, the AU guardian, struggles to maintain order while navigating conflicts with troubles and protecting his friends. Amidst uncertainty, trust and reliance between him and Dream deepen, revealing hidden vulnerabilities and the weight of past failures.

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
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

In a linear, closed off yellow-hued hallway, featuring a Symbolic Rune depicted atop the corridor entrances and windows. White light shines through the mosaic windows, and Greek pillars border the corridor in both sides Mami, Sayaka, and Madoka are cautiously walking in the middle of the hallway to reach the end, until they stop as a girl with long black hair like Homura with slightly pale skin and has black eyes with white pupils made herself known appearing from a pillar and was wearing her seemingly signature blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of white slippers and was showing her signature smile to them.
"..."
??? Looked at them curiously and then spoke. "That expression that you're all wearing..."
"..."
"Well, i won't grace it with a description. But damn this is your 900th try so good luck. Kyoko and Nagisa are waiting for you three, you know?"
"S-Sachi-san please we can try and talk this out-". Before Madoka can finish what she's saying, Sachi Akemi looked her with her white pupils missing.
"Talk this out?" Sachi scoffed "You lost that chance after what you did to Homura" -
