After Frisk goes missing, Caitlin, Frisk's twin sister goes looking for her in the the last place she saw her. MT Ebott, the mountain of dark legends, she finds a necklace that belonged to Frisk on the ground. Just like Frisk, Caitlin tripped and fell into the Underground. Caitlin finds things she never knew existed.

...I'm Undertale trash. This is basically going to be the story of Undertale retold as the Underfell version. I'm sure something like this exists already...but whatever. The story is told from Frisk's point of view, and it's the Pacifist version because Genocide scares me. Anyways I hope you like it!

It's been four years since peace and prosperity had been restored to the undergrounds where the monsters were once forced to be trapped inside. Long ago, two races ruled over Earth: Humans and Monsters. One day, war broke out between these two races. In the end of a long battle, the humans emerged triumphant. The monsters were sealed away with a magical seal. All is well until a young girl about our hero, Frisk's age, who has fallen into the undergrounds. Little do the gang find out that danger lurks around every corner in the undergrounds...

Frisk is being bullied at school. The mom instincts of Toriel, Sans and Papyrus are kicking in. [ aka #protectfriskyfrisk2016 ] * Completed as of 4/20/17.
