Y/N L/N's adventure in GenderVerse (REVAMPING) by Derek_ACreator

The Descent Begins YN LN, twenty years old and quietly unraveling, lives in the shadow of Mt. Ebott. A jagged peak that looms above the city like a forgotten god. Their days bleed into each other, marked by faded photographs, silent rooms, and a growing weight of solitude. On the morning everything changes, YN wakes to dust and ache, haunted by loss and memories that no longer feel like theirs. A package from a kind neighbor, a forced smile, a job stripped away without warning, small cracks in a day that already felt too fragile. They didn't know they would climb Mt. Ebott. They didn't plan to leave everything behind. And they didn't know the mountain would open up beneath them, pulling them into something ancient, strange, and irreversible. Beneath the surface lies a world of forgotten magic, fractured souls, and impossible beings-each encounter stitched with mystery, danger, and strange familiarity. Who will YN become in a world that reflects them like a mirror cracked down the middle? Who waits for them in the Underground? And can anyone-human or otherwise-truly escape what they carry with them? A fall begins the story. But the climb back out... will reshape everything. Read on, and descend.

You were always a curious child. One day, your curiosity took you too far. You lived not to far from a mountain, MT. Ebott, and always wanted to see what was on the top. Your parents had told you stories about the mountain and you had always wanted to see if they were true, being the naïve child you were. One day, you reached the top after a while of climbing. You looked around, not realising where you were walking and fell into a gaping black hole. You woke up to a soft voice of a goat-like monster who, ever since that moment, took care of you and loved you. She taught you magic and all sorts of recipes. Everything she knew and you loved it. But what happens when you grow up more?

Endless possibilities (Underfell Sans x Gender Neutral Reader)*BEING REWRITTEN!* by glossedweed

Word has been released that monsters now roamed the surface, and you can't help but feel slightly skeptical. You had been told since childhood that monsters were vile and repulsive creatures who wanted nothing more but human blood pouring from the palm of their hand. You didn't know what to think of the monster race, but majority of the human race did. The tension between monsters and human kind was sickening. People had told you to stay away from monsters at all costs. But that'll be a bit difficult when two skeleton brothers move in next door to you. And why bother lying? You can't deny that one of them has stuck on your mind. (Warning. There's a lot of colourful language, so just a heads up. And also, the artwork doesn't belong to me. Credits to the rightful owner.)

You the Reader didn't get to know all the Monsters, for the whole 2 years you just worked and relaxed at Waterfall until you met a certain Monster who changes your life and you change his.
