Summary
Twelve years ago, after a violent storm, a young woman was found on Omashu Beach, with no memory of her past life, and taken in by a convent of nuns. Now, Katara, as she was named, lives wondering who she was and why the ocean both saved her and cursed her, transforming her into a mermaid—a secret known only to her mentor, Father Iroh.
However, mermaids face many dangers, so when the most unlikely opportunity arises, Father Iroh entrusts the pirate Zuko with taking Katara far away, to the Northern Water Tribe. They embark on a journey that could change their lives, for Zuko is a man haunted by the pain of having lost his honor years before.

Summary
Dewdrop is a crew member of the Hail Mary, a fishing ship captained by Terzo Emeritus. Life is calm, if a little dull, hauling fish day after day. That all changes when the fishing nets pull up an unexpected catch. A living legend. A mer person. Rain.
Dew immediately feels sympathy for them, especially when Terzo plans to bring Rain back to land. In setting out to return Rain to the ocean, Dew finds himself undertaking a journey through loss, fear, and hardship; above and below the waves, to rediscover himself and find his place in the world. And perhaps something even better; found family and a home.

Summary
He's seeing things, catching glimpses of nothing between the lightning above. Fantasies of sailors who swear they've seen beautiful creatures while on the cusp of death. If his lungs weren't full of seawater, he'd laugh at how he's no better than those delusional men, how he's holding onto what sliver of hope he has left as his consciousness fades.
And then, finally, pure darkness.
When a sudden storm knocks Kayn overboard, he accepts his fate to the ocean's depths. He wakes, however, in a seaside cave, injured but very much alive, and not as alone as he thinks. Someone is helping him — tending to his wounds and bringing him food only while he's unconscious and resting, but he never sees his mysterious helper directly. Not until one day, he catches a glimpse of something that he can only describe as otherworldly, and not at all human.

Summary
He hears her cries echoing on the waves, the sound so sharp it reaches down below into the slow spiral of his nest. It is a female, the males do not possess such a crackling pitch.
She was not the first to make that sound and from his limited understanding of the species, she will not be the last to arrive, but there is something in the pitch of voice that makes him curious.

Summary
So he watches him slumber, for there is nothing else to do, or so he tells himself. Like this, he can observe all he wants, and the mermaid can’t make a fuss. He brings a gentle hand to tuck his bangs behind his ear, and traces his fingertips down his jaw.
Even if he finds Phainon irritating, even if he wishes to be alone, he can’t relinquish the fact he saved him. Found him in the dark abyss and plucked him from his grave. For that, he does not know if he should be grateful, but he knows he should be less harsh with him.
Mydeimos tries to find a cure for his terminally ill mother, Queen Gorgo, but attempt after attempt he fails. On his last chance, he captures a mermaid, a creature whose flesh should solve his woes, but he can't bring himself to kill and sets him free.
And when his father learns of such an act years later, he condemns him to drown in the same ocean where he enacted his betrayal, only to be saved by the very same mermaid who brings him to a secluded island to heal.

Summary
The Szarr pirates were not known for their mercy and Astarion had long lost the ability to care. One did not survive under Cazador's command without throwing their morals into the unforgiving waves of the ocean, and Astarion was very much planning on surviving this mess. The only thing Cazador did better than pillaging small unsuspecting ships was making enemies in deep waters.
Astarion slipped away from the chaos and into the deeper parts of the ship, hoping to find first whatever it was their captain had been so desperately searching for in the past few months.
On Cazador's orders, Astarion manages to capture a creature rumoured to be able to guide them to towards unfathomable treasures. Neither he nor Gale could have predicted the consequences of such an action.
