Life & Soul by Quillion9000 reviews
Before the start of this story, seven Humans, varying from children to teens, climbed Mt. Ebott for various reasons. No matter their reason, all seven fell into The Underground. What I can confirm for you now is this: The Eighth, despite a differing circumstance, has the same reason to climb the mountain as the first. Like the seven before him, he will fall into the Underground.

Soul of our Hearts by Congar reviews
Human magic before the Barrier was achieved through the Cooperative Connection, a bond wherein a monster gifts his or her memories, and thus a part of their soul, to a human. Discovered when Queen Toriel gifted a blind prince a blanket which she weaved in her memories of describing the starry sky far above her castle in the Monster Capital.

The Golden Quiche by Sophtopus reviews
For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.
