THEY WERE DESCENDANTS OF A LOST CIVILIZATION...

For thousands of years, they have dwelt the earth in hiding. Blessed with abilities, they were revered as gods and deities, giving knowledge and wisdom to those who seek it. And for a time, all was well until the world was at the brink of war and left mankind in desperation.   

SOUGHT FOR THEIR POWER, THEY WERE EXPERIMENTED, SEPARATED THE STRONG FROM THE WEAK...

A group of humans called the Regent  was formed to rally their kind. Tortured and  deprived of their emotions, they are forced to live as weapons within the confines of the Dome. They were called the Revenants.

THERE WERE SEVEN OF THEM, POSSESSING UNIMAGINABLE ABILITIES...

"Seven shadows. A girl trapped in glass and a crow." 

A few decades back, the Regent  had found a new designation, a new breed with abilities of immeasurable power. They hoped to exploit them but failed. 

Now they were hunted for what they are.
