Disclaimer: I don't own Percy Jackson and the Olympians or Heroes of Olympus.

This was more or less inspired by Lone-Angel-1992's Harry Potter fic Orion's Belt.

Warning: sad stuff in the first chapter, traitorous Olympians, war, pre-slash, slash, etc.

Enjoy!

This was…a disaster.

'No.' Will scoffed, angrily. 'Disaster isn't a strong enough word for this shit.'

Everything had gone to the dogs only a few short years after the Roman and Greek camps had been united. Now, considering they had been mortal enemies prior to that, one would think that it was the camps breaking out into war again that had starting things off.

Nope. Even now, the two camps stood up together against the opposition.

Or what was left of the two camps, anyway.

It had all started when Iapetus (or Bob as he now preferred to be called) managed to find a way out of Tartarus. A majority of the gods were furious, and it didn't help that so many of the demigods, even the ones who'd never met the Titan, had defended the shocked and touched Bob.

The situation had reminded the Seven and company about Calypso, and how she had been so cruelly punished for siding with her father due to their familial ties. The gods hadn't kept their promise on the Styx to release Calypso from her prison, and when Leo had managed to find her for the second time and help her leave, they had fully intended to throw her back there and kill Leo for his actions.

Bob had lost his memories, but even when he had started getting them back, he had still helped Percy and Annabeth when they were in Tartarus (granted, that was thanks to a certain Son of Hades). The gods, again, didn't care. In their opinion, the Titan had and always would belong in the abyss.

The demigods had protested this, almost every single one of them. If that was how the Olympians were going to treat an ally in the Giant War, who was to say they wouldn't turn on their other allies?

The minor gods and goddesses had the same thought. After all, they'd been pushed aside and forgotten by the Olympians before, so they had no trouble believing that they would be betrayed.

Of course, the thing with Bob and Calypso wasn't the only issue.

The Olympians had started to send monsters to attack even their own demigod children, convinced that they would bring about the downfall of Olympus, regardless of how many times they had saved it in living memory.

The gods' domains-war, the seas, the skies, nature itself, they all ran rampant as the gods stopped caring about the mortals they ruled above. Thousands of humans-mortal and demigod alike, died every day due to their carelessness.

Hades and Hestia, neither of them Olympians, ended up siding with the demigods and 'minor' deities. The demigods had been wary of the Lord of the Dead at first, but had quickly come to see just how big of an asset he was. Hades and Nico di Angelo even summoned various ghosts and monsters for training purposes and information gathering.

Hestia had been the one to keep them all functioning. When all seems lost, the feeling of having a home and family gives you strength, hope, determination, and a reason to continue on. That was why Percy had chosen Hestia to keep Pandora's pithos safe during the Titan War.

It had been a time of celebration when Hades finally confessed his feelings for Hestia, and it turned out that she returned them. At that point everything was so out of whack that her oath to the Styx to remain a maiden wasn't even binding anymore.

Nico had been ecstatic, having his favorite immortal as his new stepmother, since Persephone had divorced Hades before the fighting really broke out. In response, Hades had just smirked and told his son that, when Nico and 'that cheery brat' finally got their shit together, he would be happy for them.

Unfortunately, that was when the good memories more or less ended.

Percy ended up dying trying to save Annabeth from Medusa, only for Annabeth to be killed moments later.

Jason had been struck by lightning from his father. Usually this wouldn't hurt the Son of Jupiter, but there was so much raw godly energy in that hit that it destroyed his body immediately.

Piper was never the same after that. She stopped smiling and laughing, her eyes hard and cold most of the time, though they did soften a bit when she was surrounded by her friends. She also threw herself into training even more, quickly becoming rather talented with a bow, though she still used Katoptris when necessary. A lot of people and monsters had reassessed their opinions on children of Aphrodite, though none of the goddess's children appreciated being associated with her.

Leo and Calypso were still alive, but Calypso had been cursed, and could die at any time. Leo was working himself into frenzy, slowly losing his mind as his girlfriend's condition got worse and worse.

Reyna had died helping the Hunters and Amazons, as Artemis and Apollo were the only Olympians (now former) who had sided with them. Thalia had also died in that battle.

Frank had been attacked by a raging phoenix, whose flames were so powerful they managed to get through the fire-retardant pouch that Leo had asked Calypso to make for him.

Hazel hadn't spoken since, and her eyes had lost their inner glow. Nico was absolutely heartbroken to see his sister go through the same thing that he himself had when Bianca died, and nothing they tried to bring the life back into her had worked. She was more or less catatonic, now.

One by one, they were picked off. Lacey. Connor. Travis. Katie. Chris. Jake. Nyssa. Tyson. Rachel, who had died despite Apollo's best efforts in healing the girl. Grover, despite being the Lord of the Wild, and his girlfriend Juniper. Gleeson and Mellie Hedge, and even little baby Chuck.

Nico and Clarisse had gone into a devastating rage at their godson's death, ruthlessly slaying hundreds of monsters before being forced to retreat. Clarisse had been hit with a poisoned arrow, however, and had died three days later.

Even Sally and Paul Blowfis, who Zeus had killed in a fit of anger after they refused to tell him where the demigods were hiding. Until their deaths, the Blowfis residence had acted as a sort of safe house.

Now they were having their final battle-the last stand against the tyranny of the Olympians. It was all or nothing…

Will shot an arrow at Aphrodite, impaling her thigh, before ducking behind a barrier and out of her sight.

He looked around tearfully, seeing the bodies of his friends and family scattered across the battlefield. There were only a few-maybe five or six, demigods still alive. Will and Nico made two of them.

'We're going to lose.' Will realized grimly, beginning to make his way towards Nico, who was fighting both Athena and Ares at the same time. He wasn't winning, but he was holding his own.

For now, at least.

By the time he made it to Nico, running as quickly as he could, dodging and avoiding enemies and projectiles alike.

*Ten minutes later*

"Victory!" Zeus boomed, raising his hand in a fist as the remaining Olympians cheered. Hades and Hestia had somehow been forced to fade, and Will and Nico were the last ones alive.

Zeus launched a lightning bolt at the two demigods.

Knowing that he would never have another chance, Will leaned over and kissed Nico passionately. Just as Nico started to respond, they were struck, and their bodies disintegrated.

Will opened his eyes with a gasp, breathing heavily.

He immediately sat up, realizing that he was alive and wondering if that entire thing had been a dream.

He didn't even have time to register what he was seeing before he saw Nico rush into the infirmary, and seeing Will, ran forward glomped him in a hug.

The Son of Apollo immediately hugged him back, ecstatic to see his love still alive after Zeus had tried to kill them.

"We're back." Nico muttered, voice cracking in happy realization. "Will, we came back in time!"

"Back in time?" Will asked, breathless at the implication. "What…what do you mean?"

"Exactly that!" Nico answered with a grin. Will tried to ignore how the Son of Hades was holding his hand, but it wasn't working. "I came across a newspaper before I managed to find you."

"And? Don't leave me in suspense." Will chided, though he meant that two ways. Nico did remember that they had kissed before getting struck, right?

"If I remember stories from the others correctly, it's about three months before Percy went to camp for the first time. We need to see if we're the only ones who came back."

"And if there are younger copies of us running around." Will said, realizing that he and Nico looked the same as ever.

"True." Nico agreed, eyes taking on a determined glint as he remembered all the lives that had been lost through the years. With luck, he might even be able to see Bianca again. Though, he'd need to see what he could do to get Hazel out of the Underworld. "Will…we can change everything."

With that, Nico leaned forward and kissed Will with everything he had. Will groaned, closing his eyes and pulling the other seventeen year old boy closer.

No, the Son of Hades had most certainly not forgotten their kiss.

Please review!

Sorry it's a bit rushed (and short), but you guys get the point, right? The Olympians, with a couple of exceptions, fucked up big time. Now they are unprepared and unsuspecting of the war that's about to rain down on them.
