The Aftermath and Age of the Gods
After the war and a funeral for Percy, the gods built Mount Olympus. The hundred-handed ones, Cyclops, and Poseida collected the materials with Poseida using the powers Percy gave her.*
The others helped construct the actual palace. Zeus wanted it high and mighty, but the others wanted it small and cozy, like an actual home that none of them really had. The compromised and Zeus got his bigger place while it was still homey (Hestia was great at making it like that and asking the titanesses who did fight to help her gather supplies. Zeus was made at her for conversing with those 'traitors' but he shut up when he got glares from Poseida and Hades, daring him to continue speaking.)
The nights were horrible though. The 4 that got swallowed weren't the best in their mental state and kept on dreaming of the darkness there. Poseida slept farther away so she didn't awake them with her screams (they still heard her) and Zeus was fine (lucky him).
"Hello everyone!" It was the day after they finally finished the marble castle. Zeus was being extra loud and annoying that morning because he was in a cheerful mood. He was lucky he had gotten any sleep within the last few months.
"Shut up, dunderhead." Poseida looked really tired as she stood in the camp grounds that they had made when the 6 had started.
"Why? We have finally completed-" He was cut off by Hades walking out of his tent and sending him a dark glare. "Okay. Now, let's move in to see my glorious new palace."
"The first chance I get, I will do two things, 1) knock Zeus out for years with something heavy, like a baseball bat, and 2) move away from him and his 'glorious' place and stay there." Hades and Demeter, who stood next to her agreed. Hera was fawning over their brother like he was her dream boy. Yuck. Hestia was smiling, but there was an edge to it.
The palace was homey with all the furs and warm lights, it made Poseida a bit sleepy, especially by Hestia's fire.
The rooms were comfortable. Hestia's was like mother's private room, warm colors and it felt safe, Demeter's was like a forest and she slept on a bed of grass and dirt (which is comfier than expected) and it felt open, unlike a room is. Hera's was colorful like a peacock, but everything was off and it was cooler, Hades was dark and much like underground, but it felt right. Hers was like the deep ocean, dark and calm but wonderful. Hades had commented that it really felt like he was underwater, Poseida personally liked how relaxing it felt with the dark blue color that was layered and got darker the closer to ground it got. Zeus's was cold and but out, it was off putting and set her on edge, like she was being watched all the time and didn't like it.
They settled with it though because it was now home.
-------------------------
Then became the problem of managing the new world that they fought for. Zeus believed that men should be the only ones mainly in power and put that belief to heart. His siblings (minus Hera, because she is so love-sick that she was blind to everything. Oh how much hurt she would go through because of this), disagree but never really interfered because they had more important things to do.
Zeus was going to make himself ruler of everything, to Poseida's amusement and encouragement. She wanted his ego to suffer as he broke down at the sheer force of paperwork and responsibility that he would have to go through with this decision. Call her a bad sister all you like, it was true and she was going to enjoy it no matter what.
"I think we should warn him," Hades told her as Zeus was doing things.
"And lose my source of entertainment? No way"
"He is our brother."
"Our very annoying brother that needs to be knocked down a few million pegs, and this is the way to do it."
"We could become rulers of the underworld and sea, as we both are there most of the time. Also, it is more time away from his ego." That was reasonable, curse her brother for making her agree.
"Fine." She walked up to Zeus and took the pack of paperwork and stuff for the sea and left. It included the paper to sign for her to be named ruler. This was a horrible idea, as she had no idea how to be a queen and will probably fail at it within the first minute or so. If she did, then it would be Hades's fault for making her the worst ruler in underwater history.
(She nor Hades weren't so bad at ruling)
-----------------------------
Poseida was very surprised when Oceanus offered a peace treaty to her a few thousand years after she started ruling the seas. She thought he hated her with a passion and would try and kill her every second he got. But she was proven wrong when he approached her in her office one day.
"Lady Poseida?" He asked to see if she was free.
"I told you to stop calling me- What are you doing here idiot of the sea?" She started out with the instinctual response and then finally realized who came in. Oceanus must have finally reformed from Tar- the pit.
"I came to offer a peace treaty."
"Don't you hate me for some reason. Maybe for killing you, being annoying, stealing your stupid weapon, etc.?"
"No, I for one found that entirely amusing, especially when Kronos just stopped everything and ranted about your 'troublesome' interferences."
"Nice to know I'm entertaining. Anyway, what's with the treaty? Do I have to do anything incredible or stupid?" Oceanus huffed in laughter as she turned back to her paperwork.
"It was going to be an arranged marriage. I was going to offer one of my children to marry you."
"There it is." She deadpanned and finished a document, only to put it away and rest her elbows on the table. "There is the stupidity I've been waiting for. Why would anyone marry someone they've never met or might not have a romantic connection to?"
"All you have to do is officially marry them and stay officially married. I don't care beyond that." Poseida grimaced.
"Fine" And just like that, Poseida went from single to married.
(Amphtrite became a great sister figure to Poseida, and Triton was a good son despite him not even being hers biologically. It was nice to have help with the kingdom and stuff)
----------------------------
Athena proved Poseida's idea that pride, agnortance, and looking down on others is inheritable. She was just like her father and grandfather, thinking she was smarter than everyone else just because she was the wisdom goddess. If she were a true wisdom goddess, she wouldn't be wondering why she had so few friends, and even better, know that acting the way she does will not end well for her. Yet, she does it anyway.
Her and Athena have butted heads many times before and probably will for eternity. Honestly, Poseida was just humoring when she was waving around her wins.
In the battle with Athens, Poseida didn't care that much for the city. Athena would be a decent patron (not that her praise will ever get to the goddess, Athena did not need that), and she didn't care so it was a win-win. The only reason she even participated for any of the battle for patrons because of Amphitrite, who found every one of them very amusing for reasons that she won't tell about.
*----------------------*
The Medusa incident was a pain in the buttox itself. Why did everything have to be told by Athena's POV between the two of them or with anyone? Athena should know that one should get all accounts to paint the right picture.
A brief explanation on what actually happened, from Poseida's perspective. She was laying around on a hill for reasons that nobody but her knows about, then Medusa approached her. She offered some apples that were messed with, so Poseida politely refused (she has some manners) and got up to leave. Medusa insisted and followed Poseida, ignoring all personal boundaries.
Poseida started running as every and all distress signal in her brain went off. Her heart raced and she fought off a panic attack because she was about to get hurt again and she wanted the pain to stop forever, but it won't and now she would be helpless again as they used her.
She ran to the temples because it'll be easier to hide from the woman. Also, more people could help her. Just her luck, a temple dedicated to Athena came up and she might be able to get help from her niece. Ducking into the temple, she ran to the statue and let herself relax slightly and trying to stop the panic rising in her chest.
Athena helped her in the end, even if not in the way she thought. Self satisfaction blocked the panic as Medusa was changed and then pity for the woman to not be able to live life normally anymore and having to change her whole lifestyle.
After the transformation, Poseida left a bit of food and a map for possible places to go to for Medusa and left. Medusa may have done that, but it doesn't mean she didn't deserve something to help her along. Nobody deserves to be fully left to their own devices after their life changed dramatically, no matter what they did before. This might actually teach Medusa to learn some things, who knows.
------------------------------
Odysseus was another annoyance that Poseida could live without. The warrior was respectable, especially the way he helped his comrades in the war with Troy, but after was when everything spiralled downwards.
She wouldn't go into detail on what happened exactly, but it was enough for her to hate him and his crew. The ten year trip could have been way worse is all she was really saying.
*---------------------------------*
All and all, Poseida was contempt with her life as it was. Until she went to Montauk Beach and met a cute mortal named Sally Jackson, but that's a story for later.
