Summary
The underwater kingdom of Gillysea is dark and dank, but Regulus Black, the last remaining prince of the Mer, has never known anything else. That is, until one day, he decides to visit the surface. What he finds there is that he knows nothing about the world, and even worse, knows nothing about himself.
As sleep pulls him under, the last thought that crosses his mind is that they're even, he and James. They've saved each other, haven't they? Regulus can't help but wonder if either of them stink of doom.

Shall I become sea foam, let my voice be carried by the wind by Tsubulle

Summary
It was the life he had chosen for himself. Every step he took was so painful he would have screamed in agony if only he had a voice. But it was the life he had chosen for himself.
In exchange of everything that had made him, he could roam the human world on his own two legs, to see all of its beauty and its horror.
But being a mute bard was a heavy burden, so maybe following a witcher to the edge of the world and back could bring him both inspiration for life and his voice again ?
It’s not like he wasn’t allowed to try anyway.Series

Tales of two princesses (Fateful version?) by Jamiekeyblade123
Fandoms: The Little Mermaid (Disney Animated Movies), Good times Little Mermaid
22 Sep 2025
Tags
Summary
A more fateful version of a tale of two princesses rather than the darker, godly version that had destroyed my mind, happiness and writing schedule lol.
Hopefully this is enjoyable for everyone. Although almost all of the first chapter is reused from the first five of the lighter version although the rest will mainly focus on the movies with a little extra. Oh may Satan save me from little mermaid burnout

Summary
Just as he was comparing the different materials the royal mermaid carriages were built from to the firm wood of this human ship, two pairs of footsteps appeared right into the siblings’ view. Robin smiled in excitement, whereas Sunday lowered his head a little, but not enough to shield his shamefully curious eyes.
Sunday carefully ran his eyes from the figures’ matching black boots (ugly compared to their stunning tails) up to their torsos (covered by ragged and messy clothing, something that made Sunday’s skin crawl as if millions of little crabs were walking right on him), and finally, their faces.
A hardened face met him, flawed and hurt by scars of old, yet the lines on his face betrayed a relaxed personality. He had a mess of brown hair, shorter frames on his face, yet longer strands at the back of his neck, but as the tufts swayed in the salty wind, Sunday couldn’t help but think his hair looked quite soft…
And then it hit him as hard as being hit in the chest by an incoming, raging shark.
Brown and fluffy…
‘Is this the dog Robin talked about?’ Sunday’s train of thought came to that solid conclusion.

Summary
“WHERE,” Namjoon boomed, “ARE THE PRINCES?!”
Grand Scholar Moonhyun, dropped the stack of scrolls he’d been organizing. They floated around him like startled fish. “C-Commander Namjoon! I—I don’t—”
“You taught them last. What did you say to them?” Namjoon leaned so close his nose nearly touched Moonhyun’s. His trident clanged against the floor and left a dent.
Moonhyun gulped. “W-we covered the usual… human history, dangers of interacting with them… the—ah—the story of Ariel—”
Namjoon froze. “Ariel?”A long time ago, Ariel gave up her voice for love. Today, Jimin and Jungkook are determined to do better. With legs (mostly functional), voices (slightly too loud), and an endless supply of questionable decisions, they set out to find their happily-ever-afters — whether their father approves or not.
