Prologue: The End of the 'Great Kingdom'
About eight centuries ago...
"So, this is the end." the 'Eternal Queen' of the 'Great Kingdom' whispered, as the Ancient Alliance warships bombarded the Holy Temple. "This power that they lust after," she revealed a bright diamond-shaped jewel in her palm. "The 'Water Star'. Do they not realize that it serves merely as a foci for the Lambda Power of the Cosmos?"
"Selena-sama, what are you..." one of the Queen's retainers gasped, as they rushed into the crumbling Holy Temple. "The Water Star'... My Lady, you can't!" he protested.
"If you do that..." another retainer protested. "Your life will be forfeit! Please give us the order to counterattack!"
"No." Selena, the human reincarnation of the Water Dragon Goddess turned to her kneeling retainers. "I've already foresaw the result of this battle. This Kingdom will be destroyed in the end. That's why," she let her Divine Haki ripple out from the pedestal she was standing on. "I have to do what needs to be done." raising the 'Water Star', she encased her retainers in Life-force Bubbles and sent them skywards. "Water Star', lend me your power. Final Law, Activate!" she unleashed the power of the 'Water Star', the blinding light rippling out in powerful waves and sending the warships backwards, the shockwave totally destroying the 'Great Kingdom'. "Everyone, hear my last will. Live." the dying 'Eternal Queen' rested against a fallen pillar, glancing up as the bubbles shot outwards in different directions in the sky. "As long as one of you still lives, the 'D' will never die."
