Summary
The essence of Duel Monsters has been a game of wits and the intelligent. This same game, five-thousand years ago, was played among Egypt, a ruling empire who toyed with the very essence of monsters, life, and death. With the power of the games having reared its head, the world became a little larger, a little tougher, and a little more interesting.
Five-thousand years ago in that same day and age, a wise, ancient Pharaoh ruled Egypt alongside the high court, the Sacred Guardians—guiding the kingdom with wise and fair justice… or so the stories say as they have been uncovered in time. In the present, as his memories were wiped clean, he came to find peace with his present reincarnation, Yugi Muto, along with the help of his all-powerful Millennium Item: the Millennium Puzzle. Having battled foes, faced enemies, and wiped the fields with friends and family supporting them, the journey to become “king” is ongoing—lying in the heart of the Battle City finals and beyond.
However, what if the story was never truly finished? What if the hands of fate and his memory of his past was guided to be alongside another—blessed to give their lives another try? After all, the gods have a funny way of providing second chances.

Shadow Realm Series Bible by Cerublue
Fandoms: Tales From the Shadow Realm, Original Work
03 Oct 2025
Tags
Summary
Collected field notes. Forbidden secrets. A guide to the Realm’s laws, creatures, kinks, and kings. These are the notes of Dr. Marcus Samson, observer among the Shadows: compiled, expanded, and offered to anyone who wants to lose themselves in this world. This isn’t a fic, but the lore that ties the Tales From the Shadow Realm saga together. It will keep growing as the series grows. Other writers are welcome to draw from it. The Shadow Realm is vast, and hungry for stories. Please drop a link if you decide to create your own tales. I'd love to meet more tributes and Shadows!
(Formatting is hard! Please forgive my mistakes as I learn to work within AO3's limits. Happy to take advice on publishing bulleted outlines, if anyone has some!)

Summary
Bobby has always been Nyxarion’s pet, sharp-tongued and stubborn in a world where Shadows claim and keep. Morvane has always been her rival, wolf-muzzled, competitive, and far too proud of his infamous tongue. When heartbreak leaves Bobby undone, Morvane offers a challenge, and a chance she can’t quite ignore.
Banter turns into fire, and what begins as a rivalry might become something neither of them expected. In the Shadow Realm, laughter can be as dangerous as desire… and every dare has its price.
Author’s Note: Contains Shadow Realm cultural rules about binding/claiming that might read as loss-of-choice for some readers. Nothing is written as rape/non-con, and all explicit sex is consensual. No dubious consent.
This story is the shortest in the series, but the Shadow Realm is too big for any one story. I'm also publishing a living Series Bible: everything I’ve built so far about the Realm’s history, rules, creatures, the brides and pets, ferals, even hints of what’s still to come. Writers are welcome to use it as a springboard if you want to write your own Shadow Realm fics. I’d love to see what other minds make of this world. Drop me a link if you do, so I can devour it!

Summary
Link couldn't remember anything before waking up in the Shrine of Resurrection. He didn't remember what kinda person he was, what he acted like, what he dressed like. Nothing.
But he would like to think he didn't randomly become a darker version of himself at night.
At least it could keep the Yiga off his back, right?
AU where Link turns into Dark Link every Blood Moon.
I got the idea from the armor set and npcs reaction to it!

This is pure crack, its practically snortable bc of how crack it is. Updated will probably not be consistent and the grammar mistakes are intentional.
please beware that some things may not be tagged because so much is happening that it goes over the tag limit! I will try to include warnings in chapter notes as best I can in chapters after 6.
