"What if, some day or night a demon were to steal after you into your loneliest loneliness and say to you: 'That life as you now see and have seen it, you will have to live it once more and innumerable times more....'"
Finding himself inside a novel he was reading. 'He' is thrown, unprepared, into a daunting situation, bearing the burden of a Name no one should bear. Keeping the story under control will be the least of his worries, as he teeters on the edge of becoming the world's enemy.
It is said that a price is always exacted for what fate bestows... yet fate can be cruel sometimes.

Summary
This is a self-insert story, and yes, I got rid of Sunny because I don’t know how to write him without ruining his character. (within the scope of this story) I am also stealing a few attributes and ideas from other fanfics. (I will be putting the names below this)
Also, this fanfic is not spoiler-free for the later chapters. As of the time I'm writing this on Chapter 2216, I will reference things from later chapters if I feel like it.
This is my first attempt to write a fanfiction, and I'm taking inspiration from damn reincarnation for the aspect. I'm going to be putting in OCs. (there will be a picture)

Morgan's Annoyance-Solving To Do List by SugarElemental
Fandoms: Shadow Slave - Guiltythree
13 Oct 2025
Tags
Summary
Apparently the youngest Master in history have signed to army and speedrun his way to official War Hero title to impress his former commander, Princess Changing Star, and become qualified to marry her. But elders of Clan Valor think that he might be better fit for their other, much more favored Princess, who needs a particularly sturdy husband for any marriage to work.
Princess in question is less than happy about their idea.
(Not Canon Compliant. Actually a bit of AU, because canonically Valor's internal politics and whole Morgan's upbringing are even more toxic. I actually planned it as canon-compliant, but I'd need extensive anthropology studies to comprehend the actual canonic levels of Valor toxicity. Which I might do anyway in the future.)
Can be read as a bonus Chapter 3½ to Have You Heard?, or Kaleidoscope of Gossip.

Summary
Shadow Slave au where Sunny, Cassie, and Nephis are gone and instead there is Klein, Fors, and Amon from Lord of the Mysteries. Their pathways are their aspects.
This is just a dumb idea I had, and my first fanfic so don't expect anything good.
Go read Lord of the Mysteries by Cuttlefish and Shadow Slave by Guiltythree. Both are great books.

But everything begins to shift the night she stumbles upon a wounded dark haired boy in the streets—bleeding, alone, and far too calm for someone on the verge of death. Brought into her world as nothing more than a servant, the boy hides a secret far deeper than his scars.
As Nephis begins to question her own emotions and instincts, one thing becomes clear: their meeting was no coincidence.
A tale of hidden identities, forbidden emotions, and a bond that defies destiny.

Have you heard?, or Kaleidoscope of Gossip by SugarElemental for GriffinBorn
Fandoms: Shadow Slave - Guiltythree

Tags
Summary
Nephis and Sunny's relationship examined through gossips told about them. It was delicious in their Fake Dating Turned Real Dating arc, and this series of miniatures is meant to give similar external POV context for other stages of their beautiful trainwreck of relationship.
(In particular, I revel in how unreliable Sunless is as a narrator and how expertly does he lie to himself and I believe he shine the brightest when his ideas of what is happening are set against contrasting background of what does everyone else see.)

Summary
In halls of thought where threads entwine,
A shadow woke with mind divine.
No blade in hand, no wrath to wield,
But truths unveiled became his shield.Cassia’s gaze behind his eyes,
Could see through veils, unmask the lies.
A whisper turned to fated string,
And all the world began to sing.No chain could hold, no fate control,
The seer’s mind in shadow’s soul.
With every thread that he would weave,
The gods themselves began to grieve.What might a monster’s path have been,
If fate had whispered deep within?( Poem written by True_Vanity from webnovel :) )

Or: Sussie but with roleswap. A seer Sunny and scout Cassie fanfic.

Summary
Atop the red spire, a treacherous shadow and a brilliant angel fought. Normally, the shadow would win, only to realize he had been fooled and ultimately forced to leave the angel behind.
It was the predestined path, the correct one, the one that would lead to the best possible end. However, a moment of weakness was all it took to send it all crashing down.
Plans long in the making were made impossible, salvation became uncertain, and amidst it all, Fate would not be denied.
