Instead of staying bored under the sea, he decides to pose as a mortal and walk the Earth. Throughout ancient Greece, one small island kingdom in particular took to worshiping him, the Demetria Isles. So that's where Percy goes, to see what kind of people worship him.

He runs into interesting people. Lives with thieves, learns from priests and falls for the prince...

A God Among Men

Life in the Kingdom of Demetria

Prologue: The Bored Sea God

Being a god was boring. Utterly and absolutely mind-numbingly boring.

Sure, Perseus could have anything he'd ever want. Sure, there was this whole magical world that was only tangible for the gods. And sure, Perseus loved his family, but still.

Perseus was a young god, compared to others at least. He was the youngest son of King Poseidon and Queen Salacia. He was his father's pride and his mother's little darling. His big siblings were all rather protective of him. Which translated to Perseus leading an utterly sheltered and extremely boring life. Anything of excitement was potentially dangerous. Questing? Slaying monsters? Heavens no, the precious baby could get hurt! Perseus scoffed. The precious baby was already seventeen years old now. By human standards, he would be considered an adult! But no, no, he was far too young for the gods. He needed to be sheltered from the dangers of the world.

Well, no. No, he did not need to be sheltered from the world. He had proven that whenever he sneaked out of the palace for one of his own little adventures. But all he got in return were worried looks from his mother and a scolding from his father, regardless of the human lives he saved or monsters he defeated or even the other gods he helped out. What did they expect of him, really? That he'd stay cooped up in the palace, looking pretty and smiling gently all the time? What kind of life would that be? He wanted to slay monsters, defend the innocent and see the world.

So that was what he was going to do; for good now.

He knew the sea like the back of his hand and it was even worse with the palace. No, it was due time to see something new. Something exciting. He wanted to explore the upper world, where they walked on legs and lived without water around them. He was curious to see how that worked out. The first time he had sneaked to the surface had been at age seven, escaping his parents' watchful eyes. It had been quite troublesome, but if there was one thing that could be said about Perseus – he was stubborn, clever and tricky. Thinking back on it, that little stunt he had pulled ten years ago was most likely the reason his parents were so overly worried now and kept him sheltered all the time.

Well, he had escaped now and there was no going back. Figuratively speaking, obviously, because he could still turn around and go back home without anyone noticing he had been gone in the first place. But his urge to see and experience and explore was simply too strong. He left a letter for his parents, an apology and a promise to contact them as soon as he found a place to settle down, as well as the plea not to look for him and allow him to have this.

The only problem was that the outside world was big. So very big. Where should he go? Where would he be safe? As much as he scoffed at his family's over-protectiveness, he was aware of the dangers of the mortal world. There was only one place he could think of though, as he swam further toward the surface. The Demetria Isles. A small kingdom he has heard from the most.

They were the only kingdom to worship him.

After all, he was still a very young god. Too young for worship, normally. It took decades for a god to earn their stripes, as Poseidon had put it. To do something worthy of worship. Percy had managed that at the age of seven by accident. Well, not by accident, he had chosen to do what he did, but he had not done it to make the people worship him. The queen of the Demetria Isles had been on a boat, there had been a very nasty storm – the weather had been crazy due to another one of uncle Zeus' little fits; he had a lot of spats with uncle Hades and they normally led to very dark and stormy nights. The boat was thrown over and the queen had her youngest daughter tugged securely against her neck as she clung onto the boat, while the middle son held tightly onto his mother, but the oldest princess was drifting along in the vast sea, being swallowed by the waves. Amidst the darkness, Perseus hadn't been able to make anything out properly, but he had heard the girl's screams for help, so he made the waves stop, turned the boat back over once more and made the water lift her up until she was sitting in the boat. He then proceeded to lift the other members of the royal family out of the water and onto the boat. In the darkness of the stormy night, the young prince had called out for him before Percy had any chance to leave for the underwater palace again. The prince had asked him who he was and, as mother had taught him, Perseus introduced himself as Prince Perseus, son of King Poseidon. Not that Percy had known the people he had saved were the royal family. He just saw people in trouble and because he wanted to be a big hero when he grew up, just like his cousin Heracles, he had saved them.

Eternally grateful to him for saving the princess and in effect also the rest of the royal family, the kingdom built a temple dedicated to 'Lord Perseus'. Whispers and rumors spread about a merciful Sea God who was protecting their kingdom and the rumors reached beyond Demetria's borders. It was how word of his existence spread through Greece and the Roman Empire. Though in most places that had heard of him, he was mainly known as the patron god of Demetria. It irked him, just the tiniest bit, because he was still so young and he should have the right to chose his realm himself. He didn't even properly know what he was the god of yet. Among his older siblings, all minor Sea Gods, they had each found their very special purpose – Proteus was the protector of their father's seals, Triton was the patron-god of mermen, Kymopoleia was responsible for violent storms, Benthesikyme had taken over calm waves of the ocean and Rhode was the patron goddess of the Island of Rhodes. Perseus thought being a patron god was kind of boring. He wanted to be something more fun. Something exciting. Like cousin Hermes. Tricksters, thieves, travelers, messenger of the gods – now that was fun. Then again, Perseus was particularly fond of his older cousins. Unlike uncle Zeus, most of Zeus' children were awesome and very nice to Perseus.

So, back on track – the Demetria Isles were the only place where he was being actively worshiped. So why not go there? See what the queen had been up to since he last saw her. See what kind of a realm it was, how the people were. If they were good and kind, if they deserved his protection. If maybe, being a patron god wouldn't be that bad, depending on the kingdom. He wanted to know what his temple looked like and how the people in the kingdom behaved.

The world was a vast and endless place, so why not start on this little archipelago?

Smiling to himself, the Sea Prince reached the shore. The waves carried him onto the beach where he laid and watched the water return back to the ocean's depth, leaving him dry. His sleek azure-blue tail split into two legs as he emerged from the water. They felt a bit weird, especially the tiny ends – toes was what they were called, if he was right. Spreading them far apart, he giggled a little. What an odd sensation. He basically had an additional limb. As a breeze picked up, he yelped, face heating up as he hastily pulled his legs together and up against his chest. Humans were vulnerable. How did they manage, with their privates so exposed? He already missed the protective sheath of his dick and the scales hiding his entrance. Blinking doe-eyed, he decided to get off the sand because the sand was going places where it really shouldn't be – again, missing the scales that would protect his sensitive rear and penis from the assault. Supporting himself with his hands, he slowly stood. He was a bit wobbly on his new feet and stumbled over the sand, nearly landing on his rear again. Once again; how did humans manage? This was so utterly impractical. Wouldn't it be far safer to walk on all four? Less chances of toppling over.

Sure, he was a god and could, with some magic, help himself out, but... This was it, this was the last time he'd use his godly powers for the time being. Because as long as a god didn't use their powers, there was no way to track them down in the mortal world. He would be beyond his family's reach. A grin tugged on his lips. Time for an adventure. First on his list; find some way to protect his privates form the weather, because there was a lot of dangling happening between his legs and it was just awkward. Second on the list; find his way inside the big city on this island.

And from there on out, there would be lots of exploring and even more adventure. His fingers were tingling with excitement as he made his way off the beach and toward the tall city walls.

Author's note: I really miss my "Ambassador of Hades" fic, so I thought I could take that to the next level - turn Percy into a god, have him be adored by all the gods because he's a cute little fletchling god! And yes, other gods will come later to show Percy's relationship with them. I haven't quite decided on the fic's length yet, guess it'll depend on how much you guys like the idea - so feel free to tell me what you think. ;)

Next chapter, Percy is going to run into a group of thieves and learns his first couple of lessons about what it means to be human. Clothes, for example. Clothes are a thing you should have.

Now as with all of my other stories - if you want to know when it'll be updated, you can find it on my updating schedule on my profile!
