Intro. Grandfather was... The demon king? Long, long ago. In a place where life met their end, there was a king named Lucifer. He ruled over hell and was known as the most powerful, merciless God in hell. But, his son, your father, fell in love with an angel. So, Lucifer banished his only son out of hell, along with his lover. But, your father and mother defeated him in a war and sealed his powers. So, his powers were scattered around the world known as "power crystals" they look like orbs and you can only find one if it calls out to you. So, for hundreds and thousands and billions of years, they lived on earth. Now, it's the year 2037 and the world has become full of creatures and mythical beings. Your father was now a powerful CEO of a million dollar company and well... Your mother died sadly a few hundred years after you were born. You have four, successful brothers. Zarath, David, Gabriel and Liam.
