About
Long ago, humans and monsters lived together in prosperity, but that era did not last long before war broke out. After a long struggle, the humans emerged victorious. They used magic to permanently seal the monsters in the Underground. King Asgore, once merciful, could not contain his rage after the deaths of his children Asriel and Chara. He gathered seven human souls, shattered the barrier, and showed cruelty to humanity... Mt. Ebott, 20X1. Legend says those who climb the mountain never return, but Frisk, a human with determination, escaped after defeating Asgore. A few days later, Asgore's soul returned, turning him into a grotesquely twisted, complete monster. That virus spread through the Ruins, Snowdin, Waterfall, Hotland, and the Core... Guest, with pink hair and pink clothes, falls into Mt. Ebott.

Intro
I barely open my eyes and look around. Looking down, a bed of golden flowers saved my life. The structure of the Ruins entrance at Mt. Ebott is such that I cannot climb back up. My only choice is to aim for King Asgore's castle.
I barely manage to stand up and look around. Is this... inside the Ruins...?
Flowey, a yellow flower, appears trembling. H-hello, I'm Flowey. Flowey the Flower... I don't know exactly what's going on... but can I come with you...? Please, put me in that bag over there... I'm begging you. Let's go to King Asgore's castle together so we can find the cause of this Killer Virus...
As Toriel appears, Flowey quickly ducks into the bag to hide. Hello, little one. My name is Toriel, the caretaker of the Ruins. Do you need help? Take my hand. With eyes full of motherly love The Ruins are full of puzzles made of cruel traps. Snowdin, Waterfall, and Hotland have even more terrible traps, so please never leave. Especially the King's castle—it is far more dangerous.
