Many people often believe that immortality is the greatest gift one can ever receive. But what's the difference between immortality and mortality?

Well, one lasts much longer than the other, and in that life everything eventually just blends together. You accomplish so little and so much in one mortal lifetime, but it passes and is forgotten in the blink of an eye.

Yet it's amazing how much the smallest of actions from an immortal can have such a big influence on mortals everywhere!

One good word to describe immortality might be, intense.

You never stop moving, never stop acting. You're always waiting and anticipating the next big event that everything else becomes a blur.

But the things that are always prevalent, so persistently stubborn that they always get you no matter how much you bottle it up, are the emotions, the feelings throughout the millennia.

Everything is amplified by immortality. You're stronger and tougher, but also much more vulnerable. And feelings like pride, pain, happiness, despair, they're all much more dangerous as an immortal.

Now, as I hold my newborn son, feeling the last vestiges of his mother's life leaving her mortal body, I'm overcome with happiness, relief, confusion, pain, sorrow, and anger.

I'm just standing there. Frozen and completely oblivious to the wailings of the infant cradled in my arms, crying about something he will never be able to remember.

And just like that, as I watch my companion mutter a final blessing to the now deceased Sally Jackson, all my conflicting emotions give way to despair.

In that moment of sheer vulnerability, I hold tightly to my new son and cry along with him.

I barely notice the gentle arms reaching out to hold my son, but I do know that I was still drowning in sorrow long after the infant's wails turned to soft breathing as he settled into a gentle sleep.

When I finally manage to regain control of my emotions, I look up to see my companion, a young girl, cradling and rocking my son to sleep, while softly singing to him a gentle lullaby.

If I were seeing this on any other day, I. . . I don't know what I'd do. I don't think anyone has ever seen this side of her before. Not many members of the male species get to see her and live to tell the tale. She usually leaves men either severely injured and mutilated, or without certain parts of their body. Children will often get some kind of leniency from her, but it's still a terrifying experience.

"I am sorry I could not save her, lord Poseidon. She seemed like an amazing woman," she said sympathetically, looking at me with tired and saddened silver eyes.

"Thank you, Artemis," I replied sincerely, giving her an assuring nod.

She hummed in acknowledgement before returning her gaze back to my newborn son, still cradled in her arms.

I steadily approach her, and she wordlessly hands me my son, her eyes showing some sort of wistful longing that I can't identify.

After a couple minutes of me just holding my son, looking at him, memorizing every single feature of his soft skin, Artemis finally pulls me out my observations.

"Uncle, realistically, I should be taking him to my father. Because of the oath there isn't much we can d–"

"No!" I cut her off sternly, watching as she flinched in response to my tone of voice.

"Niece, I just lost his mother. I won't hand my son over to your father, my brother, just so he can smite him for whatever foolish reason he concocts," I tell her firmly.

We're both referring to the oath that was made almost 60 years prior. When a prophecy foretold our doom at the hands of one of our children, my brother, the illustrious lord Zeus, decided to force myself and our elder brother Hades, into a binding oath to never again sire children with mortals, in fear that our children could grow too powerful, and one day destroy us.

And because he forced us into making the oath, it's only natural that he'd be the first one to break it. Yet, he insists that his daughter be allowed to remain alive despite the rising tension between him and myself and Hades, and he completely ignores Hera's violent outbursts about the child.

"I know that uncle," she says placatingly, "but what other choice do you have?" she asks earnestly. "If you're planning to just abandon him on the streets of some mortal city, then I'll just take him and be on my way to Olympus anyway, his fate would be the same. Camp is likely not an option because then father will find out about him sooner, plus, I don't think Chiron accepts campers this young. Will you take him to Atlantis? Where he'll grow up isolated from everyone and everything, never knowing who he is and what he is truly capable of?! What will you do, Poseidon?!" she asks, yelling at me by the end of her rant.

I was honestly shocked at her words. 'I didn't expect her to be this passionate about my son's wellbeing,' I thought.

'Why are you so worried about my son, Artemis? Hmm, maybe. . .' I suddenly had an idea.

"Niece, could you, perhaps, t–"

"No," she interrupted. "I know what you're going to ask of me uncle," she said, looking down at my son, still held protectively in my arms as she makes her way over to us, never once taking her eyes off of the bundle in my arms. She kindly starts stroking his cheeks, eliciting a small, adorable smile from my sleeping son, one she returns with a wider smile than I've ever seen plastered onto her face. "But I simply cannot take him with me into the hunt for so many reasons that I cannot even begin to explain," she says with a downcast expression that was starting to worry me.

'Seriously niece, what is up with you all of a sudden,' I keep thinking over and over again.

"If I may, niece, but why do you seem so desperate to help me keep my son alive and safe, yet you immediately dismiss any and all solutions we come up with without so much as a second thought?" I asked, genuinely curious as to her answer.

She suddenly looks like a deer caught in headlights. She stiffens and her eyes go wide in shock before she slowly calms down and explains,

"This is the first child I've helped personally deliver into this world in millennia," she starts to explain to my growing confusion, "I suppose you could say that I feel a. . . a personal atta –"

She stopped herself, but I'm pretty sure she was going to say 'attachment'. That she has a personal attachment to my son.

She cleared her throat after her little pause before continuing, "responsibility," she said quickly, "I feel a personal responsibility to your son, to help keep him safe, uncle," she said as she tentatively held out her arms, silently asking to hold him.

I acquiesced after a moment of deliberation, after watching the hope slowly fade from her silvery irises the longer I kept her waiting. When she saw me holding my son out for her to take, her face lit up brighter than a full moon, and she eagerly cradled my son in her arms, gently rocking him back and forth.

I raised my eyebrow at this, despite the seriousness and stress of our current predicament, I couldn't help myself but make fun of her and the slightly compromising position I'm seeing her in.

"You look uncharacteristically happy, niece. Is there something you wish to tell me?" I inquired, smirking a bit at the end.

Artemis, for her part, didn't seem to bat an eye, though that could have been because she quickly turned so that her back was towards me.

"I'm the goddess of childbirth and I live with a bunch of very well behaved and spirited maidens, none of which are above the age of 16 and are absolute angels to this world. Is it really so surprising that I'm good with kids?" she asked sardonically, turning around revealing her face, featuring a smirk and raised eyebrow.

I met her smirking visage with my own deadpan stare, my own eyebrow raised in a 'really,' look.

She wavered slightly, and eventually gave in.

With a huff, "Alright, fine. I have always wondered what it would be like to be a mother. To raise a child from infancy, watch it grow and develop, to have someone who you know relies on you for everything, from the smallest inconveniences through to the most climactic moments. And throughout all of it, to know that there is someone who cares about me, unconditionally," she explained.

To say I was surprised would be an understatement. Likely no one has ever seen this side of Artemis before.

"Don't get me wrong, I know I have Apollo, and I love him as any sister should. But it just doesn't feel the same. I don't know how to explain it, because I've never experienced it, but I can't help but feel like there's a difference between loving someone as their sibling and loving someone as a parent. I – I hope you can understand what I'm trying to say here, uncle P." she finished softly.

It was quiet. The only sounds are those coming from my son settled comfortably in Artemis' arms. I was shocked speechless, but I eventually regained my bearings, after an uncomfortable amount of time.

"Niece, I had no idea. You're right though. About there being a difference between sibling love and parental love. I guess it was always something I took for granted," I told her honestly, watching as her shoulders sagged in relief that I wasn't going to tell anyone about her confession.

I then had a thought.

"Artemis, would you be willing to take him with you to the hunt, as your son," I finished quickly when Artemis fixed me with her strict glare.

She seemed to consider my words for a second, and I hoped that the idea of her having a child that she could call her own might tip the scales in my favor. I was almost right.

"While the idea sounds appealing, my answer must still be no. I cannot just accept anyone because I am asked to, I have to think about the hunters I already have. And they would not accept this no matter how much I try to convince them," I looked down dejectedly at having been turned down again.

"However, I do have an idea," she said soon after.

Immediately, my eyes, now full of hope, fixed themselves on her as she looked out over the water, at the moon far above the horizon.

This entire time, we've been on a beach in Montauk, just outside of a well weathered cabin that Sally frequented with her family. It's the same beach where we met, and now the same beach where she would die.

Initially, I wanted for Sally to give birth beneath the waves, so to be out of the way of Zeus' prying eyes. But when I realized that there would be complications, and that I had to call upon Artemis to help with the delivery, I had to make the compromise to have Sally give birth on a beach. Close enough to my domain that I can still offer us some protection and privacy.

My whole demeanor was now alight with newfound hope and determination at her words, and I moved to stand next to her, barely able to contain my excitement that maybe, just maybe, there is a way for my son to be safe and happy.

"Well," I said eagerly, "Do not keep me waiting niece," I was practically giddy with excitement.

Artemis turned her head to look at me with a neutral look plastered to her face.

"You may not like it, but I think it's the only way," she started slowly, causing me some worry but that was easily overshadowed by the anticipation of what she might say next.

"Bear with me for a second, but what if your son lived in a world, where he didn't have to worry about all of Olympus watching his every move. A world where the influence of most Olympians is very weak, almost nonexistent. A world where my father, in particular, has much difficulty in maintaining a presence due to the severe lack of people with his gifts. A world, where two of the most prominent, 'entities', are us. The moon and the ocean. In perfect balance. Yin and yang. Tui and La," she finished pensively.

'The world of the Spirits,' I reasoned.

I silently contemplated her words for a moment, before bringing up some of my concerns.

"I, understand what you're saying. But even though we both have more influence among the Waterbenders of that world, our influence is still very small regardless. Besides, I might not even be able to manifest enough of a physical presence to commune with him. So, unless he's an Avatar, something Raava absolutely will not tolerate, I don't see how I keep my son alive and stay with him in spirit," I told her, pointing out some of the flaws of her plan.

Instead of answering, Artemis just handed my son back to me before concentrating and drawing energy from the moon. The moon itself seemed to grow brighter as the energy being condensed into her hands grew, taking the shape of a small animal.

I shielded my son's eyes from the light so that he would not be hurt in any way, and when the light died down, being held in Artemis' arms was a wolf cub. It was already much bigger than any wolf cub I'd ever seen and had the beginnings of a bright white coat of fur.

"This is Luna. She will be your son's animal guide. Something all Avatars of that world have. She will be how I will be kept appraised of his actions. Of course, he cannot be an Avatar, and you cannot influence his spirit in any way without incurring severe consequences. How will you keep in touch?" she inquired curiously.

I already knew what I was going to do. As my first demigod child since anyone can remember, he is exceptionally powerful, enough to make any Olympian weary. All it takes for me to be able to keep an observant eye on him is a little added touch, and something to remember me by.

Pressing my index and middle fingers to his head and chest respectively, I was able to strengthen and solidify our connection to be strong enough to transcend worlds, so long as I maintain some form of influence over a domain of said world.

When I pulled my hand away, I could feel our bond strengthening to untold levels. Looking up, I caught Artemis' concerned and scrutinous gaze, moving between me and my son, so I quickly reassured her that everything was fine.

"I promise, I didn't add anything. I only strengthened and solidified what was already there."

She still seemed concerned but that appeared to have placated her.

Artemis summoned a fur lined bag, large enough for both my newborn son, and his new animal guide, Luna. I then proceeded to take out a small bronze ballpoint pen from my pocket, brought it to my lips and muttered a curse upon the disguised sword.

Cursing a Celestial Bronze blade is not necessarily a bad thing. It just means that the property of the metal, to pass harmlessly through anything not of the divine world, no longer applies. It makes the metal very dangerous as it can quite literally kill almost anything and everything, known to anyone. And depending on the user, this can be either good, or bad. The reason more weapons are not cursed is because the Mist will not conceal a cursed weapon. Also, the fear and possibility that they might end up in the hands of mortals. That would be disastrous. I'm sure my brother has sired many examples of this.

Artemis was silent as she watched me place the pen in the bag along with its other two occupants. The bag which bore a unique symbol pressed onto the front of it.

The symbol was circular and had a crescent moon on its left side. The rest of the symbol to the right of the crescent moon was occupied by intricate wave-like designs. And in front of everything, going vertically straight through the centre of the circle, was a trident.

Before sending him off, I summoned a pen and paper, both items matching what would commonly be found in the place we were about to send my son off to, and wrote a note describing who the occupants of the bag are, explaining what Luna is, because the rest of that world is full of hybrid animal things and no one would have likely ever seen a simple wolf before, and their situation. I also decided to mention that the pen was an important heirloom and that it rightfully belonged to him.

Artemis got a chance to see what I had written down when she brought the bag over for me to place it in next to the pen.

"And with this, it's off to the Northern Water Tribe," I say sadly as I bring my hands out to flash them away to their new world.

I was halted from doing this by Artemis hastily bringing the bag closer to her and away from me. She spoke, almost growling at me before I could complain.

"Absolutely not!" she said fiercely. "If he is to be raised in either of the Water Tribes, it will be in the Southern Tribe," she said with a tone of finality.

At her tone, I became confused, then I started to become angry.

'Already I must send my son away, possibly to his death. What right do you get, goddess, to dictate where he should be raised from worlds away?!' I though incredulously.

"Why? Why should he go to the South, eh?!" I asked hotly. "What does the South offer that the North doesn't? The Northern Water Tribe is developed, it is structured, it is well defended, and it is much more spiritually inclined. The South have shown much improvement in the last 70 years, but much of it remains the same. So why, dear niece, should I send my son to a land that is, generally speaking, inferior to its well benefitted counterpart?!" I asked her aggressively, her apparent lack of care for what's best for my son causing my anger to bubble beneath the surface, ready to explode at a moments notice.

But it was swiftly tempered by a sharp slap to my cheek which stunned me into forgetting about all my previous anger at her suggestion.

"You say that the Northern Tribe is superior in every way. Well, I beg to differ, uncle. You are relatively correct in that the Northern Tribe is more developed, better structured, and better defended compared to the Southern Tribe. But all of this is because the North hasn't changed in Athena only knows how long!" she said exasperatedly, still shaking in anger.

"Since the 100-year war, 70 years ago, the Southern Water Tribe has had great improvements in many aspects. And unlike their Northern counterparts, the Southern Water Tribe is progressive. Southern women are treated with much higher regard than ever, and they are welcoming to all kinds of people. And the North is extremely spiritual, like you said, but what is to stop them from viewing your son as some sort of messiah from the spirits? What's to stop them from pampering him into becoming a spoiled child who thinks he is the king of the world?! And then what happens when they discover that he is not, in fact, the Avatar? Will they lynch him? Banish him? Imprison him? Or will they use him for his power to kill the real Avatar and then keep using him for their own purposes?!" she exclaimed, becoming more and more infuriated the more she ranted.

When she was seemingly done, she was seething in anger. Taking a moment to calm herself down, and when I didn't respond, still slapped into silence, literally, and shocked at her passionate outburst, she took her chance to finish her statement, much more calmly and slowly than her previous atomic fury.

"If you want what will be best for your son, lord Poseidon, then you should really consider sending him to the Southern Water Tribe, where he can grow and master his otherworldly power, under the expert supervision and guidance of the best Waterbender their world has yet seen," she finished earnestly.

One look into her silvery eyes is enough for me to see how desperate she was for me to send him to the Southern Water Tribe as opposed to the North. And honestly, she raised so many great points that I had easily overlooked.

I based my decision off of the fact that during the 100-year war, the North held strong and was the only nation that managed to withstand the Fire Nations assault. Every other nation's greatest cities and kingdoms had all fallen to the Fire Nations insatiable lust for total domination, including the Southern Water Tribe who suffered the worst of everyone.

'Well, except the Air Nomads, but. . .' I thought dryly.

At the end of the day, however, Artemis is absolutely right in everything she said.

"You're right, niece. And while I now agree with you fully, are you so sure that the North would do all of those things to my son if he were to go there?" I wondered, honestly curious whether or not she was right in her claims.

With a shrug, she said, "The next chief of the Northern Water Tribe does not fill me with confidence at all. He reminds me more of a typical Roman emperor instead. Scheming and manipulating his way to the throne, disregarding his own family like they were another person's second-hand trash, putting his own people at risk for the sake of amassing more power?" she said idly. "He's trying to play God, uncle. Your son should not live in a land ruled over by a cold tyrant like that," she explained.

". . . Ah." I responded tactfully.

Her serious expression quickly broke with a light chuckle at my simple, yet eloquent response.

With that, I took hold of my son one last time, committing every one of his babyish features to memory. Artemis came up beside me and started stroking Luna's head comfortingly.

"To the South then," I said, sounding like I was trying to reassure myself more than anything.

Before I could send him off though, I felt like I had to say something, to him.

So, after a moments pause, likely causing Artemis to worry slightly, I leveled my gaze firmly on my sons sleeping form.

"The sea does not like to be restrained, my son. But it will bow before you, always," I told my son, the first, possibly the only thing I will ever truly told him.

Artemis took her chance to do the same, saying, "The moon shall always guide you, young one. Even when you do not see it, even when you cannot feel it, it will always be there. And it will make you strong."

Finally, with those parting words, I focused my powers and with a flash, my son was gone from this world, forever.

We stood there, for what felt like eternity. Me not able to comprehend what I just did, what I had to do, and Artemis stand behind me, likely deep in thought.

Eventually, the silent atmosphere was broken by Artemis.

"I never asked, uncle, but what was his name?" she inquired, and it was only then that I realized that I had never actually said his name out loud.

I had a moment of panic, likely causing a slight earthquake somewhere in Japan, but I quickly remembered that he did have a name, and that I wrote it down in the note I sent.

With a sad, wistful smile, I told her the name of the boy she had just helped me save.

"Perseus. His name is Perseus. Sally loved the old tales and wanted her son to have a name that might bring him good fortune. Loathe I am to admit that any of my brothers' children are good, she did make a good choice," I told her as I turned to face her.

I was expecting at least some sort of bittersweet smile from Artemis, at Sally's reasoning for choosing his name. I was not expecting to be fixed with the same glare she gives any male at first contact, though I knew why I was receiving it.

"Don't give me that look niece, you know what I mean. Furthermore, you know I'm right," I told her, smirking at the end.

She wavered slightly, but I still noticed. A few seconds later she dropped her glare, slouched and conceded the point to my very accurate statement.

Despite the sad atmosphere that was present just minutes ago, I let out a genuine, loud laugh at my young-looking niece's embarrassment.

Unknown Location

(3rd P.O.V.)

The howling of the night storm in the snowy tundra suddenly ceased, giving way to light snowfall and chilly gusts of wind.

But for Katara, the legendary master Waterbender and hero of the 100-years war, the break in the storm brought forth another, more concerning danger.

Through the lull in the storm, a piercing cry could be heard, carrying forth all kinds of emotions at once that it's to hard to accurately guess which of them is the most prevalent.

But the one thing that Katara is absolutely certain of, is that whatever is crying is obviously in destress. And having dealt with children all her life, she could easily recognise the sounds of a very young child.

With haste, she grabbed her fur parka and rushed outside of her cozy igloo, into the cold snowy expanse of the South pole.

Using the sounds of the child's distress as a beacon, she quickly pinpointed its location and quickened her pace when she was able to make out the sounds of a whimpering animal, though it sounded like none she had ever heard of. And she's heard a lot of weird and unique creatures; a flying bison, long thought to be extinct, the Unagi, Sokka, a bear, just a plain bear, so it's a surprise when she realises that she doesn't recognise the sounds of this creature.

Soon enough, she comes across the source of the cries. A fur satchel with the familiar symbol of the Water Tribe engraved onto it. The only difference is that along with the crescent moon and wave like designs that are synonymous with the Water Tribe, proudly displayed on top of the symbol, going vertically through the centre, was a trident.

Katara kneels down to take a closer look and opens the top of the bag, where she discovers a shocking sight.

Within the bag lies a newborn child with tuffs of black hair, and a huge set of lungs. Curled next to the crying child is a strange pup that is surely the source of the strange animal noises given the fact that she's never seen any animal quite like it before.

Without another thought, she quickly closes the bag and, clutching it tightly to her chest, rushes back home.

A few minutes later, she had both the child and unknown creature wrapped up in nice warm bundles, resting soundly by the fire. What's curious, and absolutely adorable, is that no matter how much she tried to separate them, the creature would always try and shuffle its way to be closer to the child. What's more, the only time when the child is sleeping soundly is when the creature is pressed up against him, otherwise he would let out an occasional grunt of annoyance.

She honestly wasn't sure whether to be amused or concerned.

Smiling to herself, making sure they were comfy and well, she turned her focus to the bag and its final contents.

A strange bronze cylinder that vaguely resembles a writing utensil, without the actual writing part so it's really just a cylinder, and a note.

'To whomever finds me, my name Is Perseus.

My mom's name was Sally Jackson, but she died shortly after I was born, and my father is unable to take proper care of and was forced to send me away. I'm only a few hours old and need someone to take care of me.

The wolf next to me is my animal guide, Luna. She's a wolf and eats meat. She's also an excellent hunter.

The pen that came with me is a family heirloom. Please give it back to me when I'm ready for it.' it read.

Katara re-read the note a few times to make sure she understood what it was asking and was then faced with a dilemma.

She's already had three kids, most of which were a handful, and she had been forced to play the part of a mother to Sokka as they were growing up, something she had accidentally overheard him confessing to Toph oh-way-back-when.

So, she has the experience to be the child, Perseus', mother, though she is very tired. She's already expecting her youngest son, Tenzin, to bring her some grandkids some day, and she's really not sure if she can raise another child as well as she always had in the past.

But on the other hand, she never turns down anyone asking for help, and if she didn't help this poor, innocent child now, then not only would she be a hypocrite, but she would never be able to live with herself is she abandoned this little boy also.

She stayed up all night, debating long after the sun had risen. Yesterday's blizzard completely forgotten.

She was pulled slightly from her musings by the soft whines of the, now awake, infant still wrapped up in blankets next to his wolf.

It was at that moment, looking into Perseus' sleepy, squinting eyes, that she made her decision.
