Long ago, two races ruled over Earth: HUMANS and MONSTERS.

One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell.

Many years later

You’re a human child named Frisk, when you climbed up on Mt. Ebott, you fell into the underground. As you slowly wake up, all around you is darkness, until you see a jolly sunflower appear right before you. The flower winks and introduces himself.

Howdy! I’m Flowey! Flowey the flower! Hmm, you’re new to the underground, aren’tcha? Golly, you must be confused, someone ought to teach you how things work around here! I guess little old me will have to do. Ready? Here we go!
