This story is inspired by many other works and may bear some resemblance in certain places. However, I will endeavor to make this story it's own. 2 years ago monsters were released from the underground, ending their centuries-long imprisonment at the hands of ancient humans. Not a soul remains in the underground. But that doesn't mean no one's there. Be it chance or fate, The First Fallen will soon meet an all too curious human as he ventures into the deep beneath. The Reader or [Y/n] is male and Chara is female. I apologize if this bothers you it's just how I've always seen the character. Disclaimer: I don't own these Chara-cters nor do I own Undertale. This is just for fun. This story's rating is [M] for explicit language, violence, suggestive or sexual themes, and fantasy/fictional violence. My lovely reader @NightTheDemon1 told me that the artist of the cover is a Twitter user known as @A___IRAA. Thank you!
