a human. . . who isn't quite human? You fall down mt. Ebbot with your lovely dog, forced to trekk through the underground on instinct alone. Luckily, you aren't one to ignore instinct. <Kindness soul> (This story is just so I can test my writing skills, so don't be surprised if I suck.) Edit 11/4/20: If your an old reader, I'm still here, and the ending is made marginally better, along with the story itself. I had to go back and reread/rewrite everything. I'm sorry, I tried.

It's been two years since the barrier was shattered... All was well until humanity's opinion and voices ruined it all. The war had begun. --------------- Although one girl had always seen the world as a sickening place... A majority of humanity was indeed contaminated, but she was one of the individuals who deserved the mercy of the monsters. From being abused and previously bullied (Y/N) had enough. She escaped her own home, only to be exposed into the havoc of the world. It made her sick. Highest rank: #16 in Fanfiction
