With each passing year, the icy tomb that surrounded the resting monarch slowly began to change the young one to prepare him for his destiny.

He became muscular and tall, his body now resembling a great warrior rather the scrawny teenager who had arrived at Nortend's frozen shores all that time ago.

His mind grew sharper like a razor's edge as all sorts of knowledge was being absorbed into his brain. Knowledge on strategy and leadership, the magic of blood and frost, how to raise the dead to follow his every command and the art of inflicting pain upon both body and spirit.

His heart and soul grew colder, no longer was he held back by innocence and naivety. He now saw the world with jaded eyes and now witnessed the injustices performed by the gods with more clarity than ever before.

Somewhere deep inside him, there was still a flame that could produce warmth. But it was well hidden behind layers upon layers of ice, designed to protect the last remaining spark of the boy who he had once been.

But that did not mean that Percy was merely sitting back and letting the magic do its work.

As the mental connection between him and his followers grew stronger, he started to issue his first two commands while his body slept.

The first of which was the reinforcement of Icecrown, as he now knew the tower was called. If they truly would have to go to battle with the gods, and Percy suspected that it would happen sooner or later, then they would to turn the tower into a fortress capable of withstanding almost anything.

And with workers that required nether food, water nor rest and carried an unbreakable spirit, it was going to take a fraction of the time it normally would have.

Similar reinforcements would gradually be made throughout the entire island.

The second was for his troops to prepare for war.

Great legions of undead were gathering, some human and some more beastlike. Giant abominations patrolled the shores and the great frostdragon Sindragosa kept a careful eye on the heavens from her perch on top of the tower.

Blades were sharpened and new weapons were put in development. Chief of which being the Plague, a sickness that gradually transformed the victim into an undead slave. It had long existed on Northend, it being the cause of many of the island's horrors, but now the possibility of it being used as a tool in battle was being examined further.

And at the center of it all were his generals.

Kel'thuzad, the undead lich who had once been and still remained one of the most powerful sorcerers in history before he was banished for the use of necromancy. This in spite of him performing said act in order to save his closest friend.

Anub'arak, the King of Spiders and the leader of the Nerubian hordes that guards the underground chambers. Him and his entire people banished as a result of a hero's poisoned lies, a fate not too dissimilar to Percy's own.

And the Four Horsemen, the greatest of all of his death knights. Each one a former hero who was banished and erased from history for daring to question the gods.

They were kindred spirits whose loyalty was unquestionable, his most trusted advisors and most fanatic followers. Each one wielded incredible power and maintained order amongst the ranks while Percy was still in his great slumber.

For five years they waited patiently for his awakening, all the while anticipating the battles ahead.

Then one day, an unholy cold light began to glow from within the helmet.

And then a pulse of raw power surged through the island and all of its inhabitants began to cheer and shout praises at the top of their lungs as the ice begun to crack.

As the transformation started to reach its conclusion, the powerful magic that heralded the arrival of the new king of Northend had slowly begun to take hold ahead of time. The entire northern hemisphere was covered in ice and the winter lasted well past May and into the middle of June, eventually reaching the Greek isles and Camp Halfblood before it adruptly began to transition into spring around the end of the month.

The gods watched with baited breath and even a bit of anxiety amongst the lesser ones, the prophecy from years prior still echoing clearly within their minds. Part of them hoped that Apollo had been wrong, that what he had seen wouldn't become reality. But deep down they all knew better.

Quite a lot had happened in those five years.

For one, Poseidon had left Olympus on his own accord and now stayed permanently in his palace in the deep ocean. In his belief that Percy was innocent, something that he had never gotten the chance to convey to his son before his banishment, the rift between him and Zeus grew into a chasm that would probably never heal. Then three years after Percy's banishment, an argument between the brothers eventually escalated into a bloody fight that shook Olympus that resulted in the ragefilled Poseidon leaving the sacred mountain in fury and Zeus taking Davos under his wing.

Roughly one year later, Davos ascended to godhood as the God of Champions at the same time Annabeth became the Goddess of Truth.

During his ascension, Davos was gifted with the winged horse Pegasus as well as a golden armor and a sacred blade forged from one of Zeus' lightning-bolts.

Annabeth was gifted with a tiara that in its center housed a third eye, one that allowed her to view inside of someone's mind, as well as a glaive and a pair of golden scales who could determine whether the accused was telling the truth or not.

Now they were officially the two guardians of Camp Halfblood, keeping watch over the other younglings as they too strives to ascend and have their names recorded in history.

Anna became feared as the Protector of Women as she made sure that nobody would attempt to replicate Percy's disgusting actions on her watch. Repeatedly hopping into the minds of the male students, she checked for any indication of perverse thoughts and even more importantly the desire to act out on said thoughts. The result was that the young men became overcome with paranoia and that the young women took control over the camp, gleefully enjoying the power they now possessed.

Davos spent the majority of his time training, sometimes alone and sometimes with the other halfbloods. When he got really desperate, he would even challenge Ares to a spar who always accepted with a wide grin. Now, he didn't always win those particular battles (Ares was the God of War after all) but these were the few instances where he actually lost so Davos swallowed his pride and learned as much as he could from those losses.

When Ares inquired as to why Davos kept picking fights with him, not that he was complaining, the young god simply replied that he was preparing for the future.

What he did not mention was that there was a tiny voice in the back of his head that kept reminding him of the actions that he had committed against his half-brother so many years ago. And that they were going to catch up to him someday...

The time had come.

Percy summoned his strength and easily broke free of the frozen cocoon, he stood up as he let his gaze fall on his generals that kneeled before him.

Kel'thuzad spoke in a raspy whisper that could chill lesser men to their bones, his voice strained after not using it in many years.

"Welcome back to the world of the living, my king. Icecrown's fortification is complete and your troops are ready to march."

Percy smiled to himself, incredibly pleased with the news. They had exceeded his expectations and he felt pride in what they had accomplished. Even though the tie between him and his followers did convey his feelings rather well, he felt the need to address them directly with his own voice.

A voice that was just as worn and cold as those of his subjects.

"Perfect, you have outdone yourselves. We can finally continue with the next phase of my plan."

He could feel their curiosity peak and he elaborated further.

"We must proceed carefully, the gods will attempt to twist anything we say and do in their favor. Any direct acts of violence against them or theirs will be used against us and they might even get other pantheons involved if they perceive us to be a big enough threat. We will have to be cunning and clever, we will send out eyes and ears throughout the surrounding territories and gather the support of those that has been thrown away and trampled upon. But first and foremost..."

He looked upon the gathering with a confident grin that was only barely visible through his helmet, for once allowing his youth to shine through his frigid exterior.

"Let us get rid of that pesky ice wall, shall we?"

-line-

Percy's towering form stood before the Great Wall of Ice that separated them from the outside world.

He drew Frostmourne and held the blade before him, the runeblade glowing ice-blue as he began to gather power.

With a great warcry, he swung the blade and sent a wave of energy flying towards the frozen barrier that had stood tall for hundreds if not thousands of years. The impact broke the structure into an uncountable number of icechunks that was sent flying only to crash into the ocean with great force.

Percy raised Frostmourne in triumph, he turned towards his people and raised his voice.

"The time has finally come! No more shall we be forgotten, disgraced because of the actions of those who think themselves above us! Now is our time to bring them down, let us remind them that we will never let them walk over us!"

The masses cheered and Percy felt a deeper sense of belonging than he ever had in the past. They were his kin and he was their ruler, yet at the same time they were one and the same. Thousands of minds working as one.

He turned towards the Arch Lich beside him.

"Send out some of your pupils, preferably those that look the most human, to the lands closest to us and let them know that we mean them no harm. But tell them to be careful with their words as they can be interpreted in a number of ways. We do not need to fight a war on two fronts. Begin to also delegate spies to the areas closest to Greece."

Kel'thuzad nodded and immediately set off to perform his task.

Percy smiled to himself, everything was coming together smoothly.

Soon enough, they would all regret turning on him.

And he had something quite special planned for that treacherous half-brother of his...

For reference, I am counting the actions that the gods commit in the classic mythology as canon. And in that light, many of the Greek Gods are kind of despicable people when you really start to think about the actions that they commit in those stories...

And on that note, Davos does have reasons for behaving the way that he does and they will be revealed soon enough.
