Is The Abyss Ocean World Based On A Real Place?

Ishida, a young man, unexpectedly meets a girl named Rhina by sheer fate. But before long, a war erupts and they are captured by soldiers led by the malicious Lieutenant Monte. The lieutenant gives them a dreadfully simple choice: leave their homes in search of a legendary "lost city at sea," its immortal king, and bring back a mind-boggling amount of gold, or have their mountain reduced to ashes. Ishida’s father had set out in search of the place, too, but never returned. The journey will take them across oceans, sun-scorched deserts, and over perilous mountains; but most importantly of all: the two will discover their true selves will discover their true selves when they confront what will determine their fate. The questions remain: will they be able to find the lost city at sea and bring its treasures back to the avaricious lieutenant before time runs out? Or, perhaps the place they are searching for is simply non-existent?

Not long after getting married to my husband, he says he wants to teach me how to scuba dive. My leg cramps when I'm practicing alone in the deep sea. However, my husband, a swimming instructor, chooses to save his unattainable love—she's jumped into the sea to commit suicide. I don't ask him for help. Instead, I allow myself to slowly sink. In my past life, I stopped my husband from leaving. He saved me with gnashed teeth and allowed his first love, Millie Quirke, to drown. By the time he went to save her, she'd already disappeared in the water. He comforted me and told me it was okay, that he was glad he'd saved me. However, one night, he brought me back to the seaside. Just as I let my guard down, he grabbed my neck and plunged my face into the water. Then, he dragged me out before I could suffocate. "You were just cramping—it would've passed! But Millie got dragged away by the current because of you! You can remain in the ocean with her!" When I open my eyes again, I'm back to the day I was scuba diving.

Thousand years ago, the great and powerful city of Atlantis existed in all its full glory ok Earth. Today, Atlantis is but historical ghost and the only remnant of the myth of the lost Nation is a girl called Ava.

The Dark Below is a steam-punk/fantasy world filled with the darkness that rests beneath a wavering tide. Generations ago, Gods from the depths below rose from the black seas and in doing so, caused a great flood that would have destroyed all of humanity if it was not for the ingenuity of survival. Living among The Dark Below has come to pass, but now four warriors must come together in hopes of forging a brighter future.

In my past life, I was performing emergency pipeline repairs 300 meters beneath the ocean when my oxygen line ruptured. I swam back for help, only to have my wife, Summer Yates, and her first love, Zachary Gibson, lock me out of the diving bell. Not only did they ignore whether I lived or died, but they also started live-streaming an extreme no-oxygen endurance challenge to the entire internet. In the end, I suffocated and drowned. Even after my death, Summer and Zachary smeared my name, calling me a deranged saboteur, while they ran off together with my massive life insurance payout. When I opened my eyes again, I had been reborn to the exact moment I was banging on the hatch. Right on cue, Summer's sweet, teasing chuckle came through the comm. "All units, don't open the hatch. Carter wants to attempt an extreme challenge today. He's going to swim back to the surface without oxygen!" Immediately after, Zachary's voice followed, trembling with excitement. "Babe, the sponsors said if Carter succeeds this time, I'll be the lead director on next month's million-dollar documentary series!" In my past life, I had begged them through mouthfuls of blood, only to be met with Summer's impatient urging. "Stop wasting your energy. You should save your oxygen and start swimming up. You're such a strong swimmer. Just hold on for another half hour, and you'll make Zachary's dream come true!" Now, as I listened to this pair of scumbags plot against me, I sneered and cut the communication. I raised the highest-powered underwater cutting torch in my hand and aimed it directly at the main load-bearing cable connecting the diving bell to the surface vessel above. They wanted me dead, so none of them would be leaving alive either.

Year XX26 when a plane had gone missing. No one has heard from it since then. Search parties were called off and passengers were declared dead. People tried calling out to them through their phones. They hear it ring but no one answers. Nathalia Trayce's father was on that plane and she's determined to find out where or what exactly happened to him; by going to the place that her father was suppose to go. Hoping to find more clues, she boarded a plane passing through the Pacific Ocean when an unexpected thing happened; their plane crashed and they suddenly found themselves in an underwater land. The Atlantis, where they found out that they were responsible for the missing planes in order to save them from the government. At least, those who posses Atlantean genes - a superior gene that help improve their physical and mental abilities. But why can Nathalie hear the thoughts of sea creatures - an ability that is suppose to be for Byron, who's the said reincarnated demigod? Trained by an Atlantean general named Skyr, and learning that her ex-bestfriend, Trei, was actually one of the Atlantean rebels. Nathalia had to choose which side to take. Or in her case, who to believe.
