Chapter 1: Homecoming

~Vincent's POV~

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. Legends say that those who climb Mt. Ebott never return. When I first heard this story I thought it was pretty cool, but when it came to us humans sealing monsters away it sounded really cruel, however, my mother said it was just a story. If only I could tell her how wrong she was. It all started 3 years ago, I was 19 and I flunked out of college and because of it I moved out of my house so I wouldn't be a burden anymore leaving my mother and 11 year old sister Izabella. Izabella begged me not to go, but I told her it was for the best. I bought myself a ticket to New York City hopefully to give myself a fresh start. I am now 22, living in a decent apartment with my girlfriend Sandy (who followed me to NYC), I work as a part-time bartender and writer. Sandy decided to become my editor (go figure). When she appeared at my doorstep one day while I was cooking I immediately freaked out and asked her why she was here. She said that my mom told her what happened and she was a little upset when I didn't call her...oops. She then explains to me that she dropped out of school, packed her bags and came to NYC. Before I could scold her for that she told me that she would rather have me in her life then school. I didn't know what else to say and I couldn't send her back when she came all this way. I hugged her and welcomed her in my or I should say "our" home. For 3 years it was going really well, Sandy was not only my editor she got a job as a library assistant whiched payed really well. Unfortunately on April 21, I got a phone call from my mother (who I still talk to) when me and Sandy were watching a movie on a Sunday night. When I answered the first thing I heard was crying, "Vincent! Bella went missing" she said. I couldn't breathe for awhile, but when I could I asked mom when did Bella go missing, "She was on a camping trip with Daniela and she went for a walk near Mt. Ebott an she never came back!". My mother then explained that even the police couldn't find her. I told my mom that I would take the next flight to California and come home to help. I ended that phone call and rushed into my shared bedroom with Sandy, "Vince whats wrong?" she asked while I packed my bags. I told her what happened to Bella and she was just as shocked and worried as I am. As I packed I started crying causing Sandy to hug me, "Its my fault" I said "No its not" "Yes it is. If I was still there then this wouldn't have happened" Sandy breaks the hug and holds my face with her hands. She wipes my tears with her thumbs, "Listen to me Vincent, none of this is your fault ok. You left because you thought it was the right thing to do. And believe me I think its very brave of you to do all that. Which is why I'm going with you" I nod "Thanks babe".

~Timeskip to California~

~Sandy's POV~

Vincent and I made it to California at 11:30 in the morning. Vincent looked restless, I don't blame him though his 14 year old sister is missing and he looks like he could have a heart attack any second. I managed to drag him outside the airport and have a taxi pick us up. Vincent told the driver where to go and we were off. I wrap my arm around my boyfriend while giving him a reassuring smile. It seemed to work cause his head started to rest on mine. The reason I stayed with him for as long as I have is because when I heard he left I was upset that he didn't tell me. He'd probably tell me to stay, but even that wouldn't stop me. I couldn't continue school without him so I told my parents I dropped out and followed Vincent. They didn't like the fact that I dropped out of school, but they later understood why I did it. Anyway, the taxi reached Vincent's mothers house in Sylmar. Vincent payed the nice man and he left after we got our bags. Vincent knocked on the front door and soon his mother Gabriella opened the door. Her eyes looked puffy from crying so much. When she saw Vincent she hugged him immediately and thanked us for coming.

~Vincent's POV~

Moms house looked different last time I was here. Then again I haven't been here in 3 years. Thats 3 thanksgivings and 3 christmas's, but never birthday's. I shipped many gifts to Bella on her's or mom's. Mom, Sandy, and myself sat on the couch as I was told everything. I learned that Bella had been missing for 5 weeks and the only clue the cops have is that they found her footprints going towards Mt. Ebott. All I could think of was, 'Why did you go to that mountain Bella?'. Bella was just as curious about the whole "Humans vs Monsters" story as I was when I was her age, but I would never go near that mountain. I heard a rumor that a kid named Frisk went to Mt. Ebott weeks before Bella did and was never seen again. A couple of hours passed and my mom went to her room to take a nap and I was standing outside wondering what the hell was I gotta do. "Hey" Sandy says behind me. I turn my head slightly letting her know I was listening, "You know the cops DID say they found Bella footprints on Mt. Ebott right" "So" "Well I've been thinking. If we check it out ourselves maybe there's something that the cops couldn't find" I looked at her "You want to break into a crime scene" she shrugs "Maybe" I think for a moment. Two things could happen, we could get arrested or we could find more clues. I then made my decision, "Sounds like a plan, but I think I should do this alone" "Seriously?" "Yeah. She's my sister and its my job as her brother to find her" "What about me?" "I need you here with my mother. The last thing she needs right now is to be alone." Sandy nods. I went into my mothers room and she was still asleep. I went up to her and kissed her forehead promising her I would bring her daughter home. I quietly exited her room making a quick stop to my old room to change. Once I was done I looked into the mirror to see my outfit: I wore an orange zip-up hoodie (Sandy gave it to me for my birthday saying it looked good on me), a black t-shirt, dark jeans, and my grey hightop sneakers. Afterwards I made my way towards the front door. Sandy stopped me for a second. She hugged me wishing me good luck and telling me she loved me. After a quick kiss, I took the next bus leading to the trail to Mt. Ebott.

~To the top of the mountain~

~3rd POV~

Vincent found where the police searched for Bella and he searched everywhere, but found nothing. The sun was setting and he was about to give up when he realized that the cops didn't search the big hole on Mt. Ebott. He knew he shouldn't look there, but something told him he should. He stood at the edge of the big hole that looked deep enough to jump or fall to your death. Vincent then thought maybe Bella and Frisk fell down, but quickly shook that thought away. He tried to see if there was a way down safely, but the floor beneath him crumbled and he fell down the hole screaming, "This is gonna huuuuuuuuurrrrrrrrrt!".
