DOCTOR GASTER LEAVES THE VOID by Geomultiplikator

Summary
"From the warm, black and white Abyss emerged slim but strong silhouette of A.D, floating towards me.
Breathing was possible in this void, and being in it felt like being immersed in warm honey.
Despite this at first I felt fear: Watching those majestic horns below me grow larger and larger as he swam closer, made me think of a sea predator rather than interdimensional lover.
After what seemed like an eternity, eternity fulfilled with very mixed, only half-conscious feelings, he was at the same altitude as me.
Fear began to fade away, when I saw his full body.
He wore only a black cloth clinging to his hips, tight from the muscular shape of his long legs.
He had perfect physique: Slim waist, but a wide chest. His muscles were covered by lengthy, clean white fur, floating chaotically in bichromatic warm substance.
His feet were pawed, but his hands were more human-like, his fingers sharp.
His horns were long and rearward.
His face was perfectly symmetrical and beautiful.
His shining eyes were the only colorful thing in the void, black and green like obsidian-emerald galaxies with golden pieces.

Summary
An unfortunate accident one dark winter night sweeps you off your feet and leads you into a chance encounter with a house full of skeletons! They’re charming, witty and punny all around, but for reasons only known to you - you escape their friendliness intending to never step foot near the woods, or the skeletons, again… or that was the plan at least. What you couldn't have expected was that they're rather stubborn, and for some reason very intent on befriending you? No matter how much you avoid them or how many excuses you provide - they just keep popping up?! Why you?! Why now? And why are there so many?!
Will you be able to ward off your new skeleton suitors and keep your age old secrets, or will you succumb to their wily charms and submit yourself to their affections despite your unnatural circumstances? Will you be able to come to terms with befriending them or will you abandon it all, leaving them and all they are in the dark…
A tale as old as time, in which the reader goes through all 5 stages of grief trying to avoid the skeletons, with very little success and a ridiculous amount of shenanigans.

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new maical coinhabitants on the surface? How far would they go if they could weaponise their magic?
