How about a short story where Poseidon falls in love with a mortal and has to face the challenges of a forbidden romance? It could have elements of forbidden love, divine intervention, and the struggle to overcome the odds.
It could involve Poseidon's battles with other gods for power or his attempts to protect the seas from various threats.
A possible plot could be that King Poseidon discovers that some humans are polluting his ocean. He gets angry and decides to send a series of small tsunamis to the coastal areas where the pollution is coming from. But then, a young human girl who loves the ocean dreams of Poseidon and pleads with him in her dream to stop. Moved by her love for the sea, Poseidon decides to give humans one last chance to clean up their act.
In the deep blue sea, King Poseidon was on a quest. He had heard rumors of a magical conch shell that could control the tides better than his trident. He swam through dark trenches and colorful coral reefs. Along the way, he met a wise old turtle. The turtle told him that the conch shell was guarded by a giant kraken. Poseidon wasn't afraid. He faced the kraken, fought bravely, and finally got the conch shell. With it, he could make the tides even more predictable, ensuring the safety of all sea - faring creatures.
One possible plot could be a story of cooperation. Maybe there is a great threat to the world of the Greek gods, and Athena, with her wisdom, and Poseidon, with his power over the sea, have to work together. They could start off distrusting each other due to their past rivalries, like the competition for Athens. But as they face challenges, they gradually learn to respect and rely on one another's strengths.
In this fanfiction, Percy could be caught in a love triangle of sorts. With Aphrodite as his mother, love and relationships might be more complicated for him. Maybe he falls in love with a mortal, but Aphrodite has plans for him to be with a demigod who can help strengthen the power of their family line. This would create internal conflict for Percy as he has to decide between following his heart or fulfilling his 'duty' in this fan - created family dynamic.
Once upon a time, Poseidon was angry with a mortal fisherman. The fisherman had unknowingly fished in Poseidon's sacred sea area. Poseidon sent a great storm to the fisherman's small boat. But as the fisherman pleaded for mercy, Poseidon relented and calmed the sea.
A plot could involve a prophecy that the union of Poseidon and Demeter would bring either great prosperity or great disaster. This prophecy sets the stage for their relationship. They start to secretly meet and fall in love. Poseidon might use his powers to create special underwater gardens for Demeter, and Demeter could make the lands near the sea more fertile in return. But as their love deepens, the other gods start to notice and some, like Zeus, might be worried about the implications of the prophecy. So they try to keep their relationship hidden while also trying to figure out how to deal with the prophecy.
It could be a story full of adventures in the sea. Poseidon, as a child, might be exploring the underwater world, making friends with sea creatures, and learning to control his powers. For example, he could be trying to create small waves or communicate with dolphins.
In 'Poseidon the First Stories', there might be stories about his relationships. He has many affairs and children. His relationship with Amphitrite is a significant part. He had to court her, and their union led to various other stories, like the birth of some of his important children who had their own roles in Greek mythology.
The Poseidon Adventure is based on a fictional story, but it was inspired by real - life sea disasters. It's about a luxury ocean liner, the Poseidon, that gets capsized by a huge tidal wave. A group of survivors then have to fight their way through the upside - down ship to reach safety. There are various challenges like fires, flooding, and the constant threat of the ship collapsing as they make their arduous journey towards the hull's bottom, which is now the top in the capsized state.
