Five Nights at Freddy's

My Celestial Beasts

by Adaya_Hearts

You have always been fascinated by marine life. Always. Of course your first job would be as a Caretaker for magnificent and exotic creatures that could have only been found in fairy tales. Except they're not.Here, you find how horrible they have been treated, and you want to change that. Little do you know, your act of kindness rewards you with being the favorite of two leviathans...[Just slow updates cause I'm Hella busy. But I will finish this book!]

Claw at the Stars

by vivisols

After spending your entire life in the ocean, you unexpectedly get captured by humans and brought into some sort of... aquarium? You want nothing to do with the place, but alas, your attempts at escape have been consistently foiled. It doesn't help that the only other two mers in this strange place, Sun and Moon, seem to have no qualms about being confined to their tanks and doing tricks for the humans.In fact... they don't seem to want to leave at all, much to your dismay.

Behind the Glass

by bkbubble

After a foolish mistake leads to you getting captured by humans, you're trapped in a large facility built for the sole reason of studying and experimenting on marine life. Most specifically - mers. With danger at every corner you have to remain vigilant. From the tests they put you though to the lucky escape, you can't afford to get distracted... but unfortunately the yellow mer you've befriended is taking up more of your thoughts than you originally planned. Now you have to protect yourself from the humans, while protecting your heart at the same time.

Celestial Depths

by ErenEvune

Well, there are many ways being stranded, alone, on an oceanic alien planet could be much worse.---You're stranded on planet 4546B after the Aurora is destroyed and most if not all its crew killed. Two of the locals seem to be oddly interested in stalking your every move as you struggle to survive while waiting for a rescue that may never come.You just really don't want to be eaten and wish they would stop taunting you.

Seafoam Stars

by ErenEvune, HollowTea, Pterolem

Sun and Moon meet you as young mers and you all become lifelong friends, even when as you grow life keeps you from visiting as often as you like. You don't meet Eclipse for a long while, though he's a great Big brother to Sun and Moon and, of course, a menace to you and society (where do you think the boys learnt it?). You wish to know more about your aquatic friends and spend as much time with them as possible, they're probably the reason you found your passion for all things related to the deep sea.aka, starting as a series of one-shots for Mermay 2023! (and beyond!) Platonic DCA Mermay Challenge is from intistone on Tumblr and Ao3.All of these will be connected in the same AU unless said otherwise in the beginning A/N (there's only a couple that aren't AU canon though). If required additional chapter specific tags will also be in the A/N. There will be bonus prompt chapters for when we had several ideas we wanted to write for a prompt!

Sub Celestial

by RandomDoodlesIDK

“Careful,” a voice chastised, whatever had grabbed you pushing you to the surface.Gasping and hacking, you barely have the ability to focus on what you’re currently sitting on. As you finally catch your breath, you finally notice the large figure breaching the surface of the water not far from yourself and the platform.Your eyes locked onto the massive red eyes staring down at you.You might be screwed-Crashlanding on an alien planet where the local giant fish try to adopt you probably isn't the best for your mental health.

Beyond the Glass

Every day is filled with happiness and peace, and there's nothing left to want...That is until you start thinking of the future, and the possibility of what could be the greatest adventure of your life.

Become One with the Sea of Stars

by Obsidian_Goat84

It was one thing to end up stranded on an alien ocean planet, light-years from earth. But, it was a completely different thing for there to be sentient fish people on said planet who could try and kill you if you so much as looked at them wrong. Maybe it was a blessing Yvette ended up with one of the friendliest of them to decide they were best friends. Though, the one outside their bedroom window at night keeps watching them with murderous intent. Is that a child? AND an even bigger fish person?! This'll be an interesting...

The Only One Allowed to

by Crabas_Lordes

The distant rumble of darkened clouds did not motivate the minisiren. Nor did the setting sun. The day threats have been avoided, luckily. Bit Bit had deterred a feast from ospreys and seagulls, and luckily no bigger eyes caught sight of them. But night was a different monster.
