Sea Breeze is a mare with big hopes and dreams. She always wanted to be a singer, like the famous Sweetie Belle, but instead found Eden, a city in the Maretlantic Ocean. What once was a under sea utopia has gone to hell. The inhabitants have been driven mad by excessive use of a DNA-changing magic called 'Euphoria', and it's recharger 'Bliss'.

Sea Breeze must find a way back to the surface, along with Pearl, a young filly with extraordinary powers. She will fight alongside with some of the few sane ponies, and tackle a threat even larger than the lunatics that dwell in Eden: The Founders.

She will need an arsenal to take on Eden's madponies and psychopaths. But in the end, a choice will need to be made… one that will change the world.
