Prologue

It had been a very bad day for one Perseus Jackson, when Thanatos arrived to claim his mother's soul, after an attack by a Hellhound. It was his seventh birthday and his mother had planned a party for him at their home in New York. Sadly, in the middle of cake a Hellhound had come running out of the wall, intending to rip the young demigod apart.

However, at the last possible second, the boy's mother saw the Hellhound, and jumped in front of the creature in an attempt to save her child. Instead of protecting her son, she merely took his place. In his rage and despair at his mother's death, Percy strangled the hound to death. And such is the scene that awaited Thanatos upon entry of the Jackson family home.

Chapter 1- Despair in Death

(One Month Earlier)

Thanatos was called into Atlantis, by Lord Poseidon for a special assignment. Generally, when a fellow god made a request for a special assignment, Thanatos ignored them and went on about his business. However, when he saw Poseidon's face during the Iris- Message he could not say no. Well, that along with the fact that Poseidon was an Olympian; the Lord of Death could not simply refuse him.

He quickly made his way past the palace guards and into Poseidon's private chambers, where they would hold their meeting. Poseidon wanted to keep his request a secret from his wife. With that information, Thanatos figured the only logical explanation for what the God of the Sea could possibly want, would be that he wanted help protecting his mortal lover from death (a.k.a.- him), which was something he could not do. Even, he could not interfere with the plans of the Fates.

Before too long he was standing in front of the door to Poseidon's private chambers. Deciding to do the respectful thing, Thanatos knocked loudly causing the door to creak open and Poseidon to call out, "Enter!"

As he walked inside he began to look around, taking in the majesty of Poseidon's palace. From the beautiful sea green walls, carved from unbelievably fine oceanic materials, designed in a way to resemble the waves themselves, to the granite floors carved just so, in order to look as close as possible to the sandy shores of an amazing beach in the world above.

Not exactly my cup of tea, Thanatos thought, although, this is quite a beautiful palace.

Soon upon entering the vast walkway beyond the door, the death god entered Poseidon's bed chamber itself, only to find said god sitting in a very comfortable chair in the farthest corner of the room, looking as though he had lost his best friend.

Thanatos knew that look very well. It was a look of mourning among the gods, when one of their mortal lovers or children was on the verge of death.

Recognizing the look on the sea god's face, Thanatos knew that he was correct on his assumption as to why he was called to Poseidon's kingdom.

It actually pained Thanatos to have to be the one to tell his fellow god that he could not defy the Fates, and save his lover, for even Thanatos knew what it was like to love a mortal and then watch as they die while you lived on for centuries longer.

What made it worse was that Thanatos was forced to make sure that his past lovers stayed dead, which was something no-other had to do.

"Hello, Thanatos," Poseidon began, "I'm happy you are here-"

Thanatos just chuckles drily, causing Poseidon to frown. "What is so funny?"

"Sorry, it is just that among most, death is not something that people are happy to see."

Poseidon just frowns again before replying, "True as that may be, I am in need of your assistance if you wish to help, but first I must ask you to swear on the river Styx, to tell none but those mentioned in the rest of this conversation. My wife would be quite enraged, about what I am about to ask of you."

Thanatos quirks an eyebrow before responding with, "I swear to your terms, milord."

Poseidon nods accepting the death gods' oath. "Ok. Good, now, on to the hard part. Earlier this week the Fates approached me as I was making my morning rounds, and told me of a coming tragedy, destined to happen one month from now. They told me that a monster was going to attack my child on his seventh birthday, and while my son will survive, his mother sally will-"

"I'm going to have to stop you right there, Lord Poseidon. I cannot defy the Fates. No being, save for the Primordials, have that ability. I cannot help you."

Poseidon merely nods his head then response, "I already know, Thanatos. I am not asking you to. The Fates told me her death could've been avoided had she remarried a mortal with an incredibly human scent. However, she did not, and now her death can't possibly be avoided. It is my son whom I need your help with."

Thanatos just looks at the fellow god quizzically, prompting Poseidon's response.

The sea god licks his lips before continuing. "Well, the Fates also told me that without his mother, Perseus will not survive long. His scent is far too powerful. Untold amounts of monsters will attack, until he is dead as well. However, they told me this can be avoided, if a god becomes his patron immediately after his mother's death, and helps to train him, and look after him. There is little I can do, because I am his father, meaning that the Ancient Laws prevent me from interfering. That is where you come in. Since, your presence will be there already what with so much death, perhaps you could take him under your wing? Metaphorically that is, of course." He finished eyeing the God of Death's majestic wings.

Thanatos sat and thought for a few moments. Did he truly wish to gain a champion, and save the son of the sea god? Did he really care enough to sacrifice time in his busy schedule to train a seven year old demigod?

Perhaps, Thanatos mused, once he is trained I could allow him to assist me in monitoring the souls that escape from the underworld. It would certainly help with the work load. Plus, it would not be wise to offend an Olympian, considering I am only a minor god.

After affirming that in the long run, it could be possibly beneficial to him, Thanatos consented, "I will assist you, milord."

Gratitude showed clear in the eyes of the elder god, as he smiled and replied, "Thank you, Thanatos. If you never need a favor from me, do not be afraid to ask, and remember; one month from today!"

(One Month Later)

As Thanatos made his way up the stairs, he noticed the unusually powerful aura of the young half-blood. With the intensity of this aura I am not surprised he was attacked at this age, Thanatos thought, even for a child of the Big Three, his aura is immensely powerful. Could he be the child of the Great Prophesy?

Upon reaching the door of the Jackson's apartment, Thanatos did not pause to enter the house and walk straight to the body of Perseus' mother, with his black iPhone in hand, checking to make sure his presence reaped her soul, and sent it straight to the underworld.

"Who are you? Get away from my mommy!" Thanatos barely registered the seven year olds' shout before he was tackled off his feet.
