I remember my mother telling me a story of how Monsters and Humans used to live peacefully on the surface in harmony. Nobody held any grudges, and nobody fought. They just lived their own lives. But, an argument had risen between the two races. Thus, a war started. It was hard and long, but in the end miraculously, monsters were victorious. And so, the humans were banished deep underground with a magic spell.
That's how we ended up down here in the first place. My father died in the war before I was born, so I never knew him. Mother told me about him though. He was very brave, and he also was a mage. He knew 6 other mages that he was very close to. These 6 mages had built a portal down here that could transport up to 8 human souls aboveground. A child went into it and never came back. One by one after the first child disappeared, the 6 mages went inside as well. None of them made it back home. Because of that, the portal was sealed off from the rest of society. By this time, I was only a very young child.
And as I got older, my mother grew sick. She only got worse over time. For my ninth birthday, she gave me a heart-shaped locket that played the most calming melody. She said it was a family heirloom passed on for at least five generations. Someone in our family apparently got it at the beginning of the war somewhere. It is my prized possesion, and I wear it all the time, in memory of my late mother.
But now, I'm going to find out what happened to those mages, and that child. I want to know if they are alive. It pains me to think of the fact that a majority of the human race could care less where they are. I'm going to take action. And it all simply began with a feeling of sheer determination.
