Y/N L/N's adventure in GenderVerse (REVAMPING)
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.Complete![Underswap love [complete]](https://img.wattpad.com/cover/212776827-256-k241755.jpg)

Fallen Under
Fallen Under is a full-length fan-novel of the game 'Undertale' set in 'Underfell'. This work will not have anything sexually explicit, though there is a (major) gore warning. It is light of heart, but some dark themes including suicide, abuse, and murder are explored. Mt. Ebott is famous for the woods that a child may wander into and never return. In legend, monsters snapped up children from villages, hid in dark corners, and ate the souls of the weak or unprepared. When a young child chooses to flee into the mountain rather than face human capture, they find out that these monsters might not just be characters in old children's stories. Frisk Foster, an eight-year-old child cursed by hereditary blindness, falls into a cavern full of merciless monsters, all of which want nothing more than to steal their soul. Armed with only their sense of justice and kindness, Frisk must travel across the underground to get back home. Yet when faced with the terrible truth of the consequence of their escape, can they truly find the will to complete their mission?
