A/N: Since today(Dec. 6) is my birthday, I decided to give you all a birthday present–a new Jeyna fanfic :) Enjoy! Cover image credits go to alexandrabirchmore on deviantART

A faint drizzle of rain had begun to fall from the overhanging clouds. It foreshadowed the terrors to come, a great storm of the likeliness that this earth and all the intertwined worlds inside it had never before looked upon. The light raindrops tickled Jason's skin as he walked upon his old home again. It was a sight he had never seen before, and not a good one at that. Camp Jupiter lay in complete ruins, and even Terminus was too tired to even say a word. Griffins were attacking, and the legion, so strong and undefeatable in war, was having trouble defending the Via Principalis. Camp Half-Blood, when he had left, wasn't as bad as this. But they had so much less people, and who knew what was happening there now? Jason silently prayed that all his friends were still alive, Leo, Percy, Annabeth, and Piper. If Piper, his gorgeous girlfriend, died–he didn't know what he would do. Jason's thoughts suddenly veered to somewhere he didn't want to go. If Reyna died, he…

"Jason!" Hazel screamed, upon seeing him, dodging a griffin's claws. Perfect timing. Jason swallowed his guilt, temporarily forgetting about the thought previously on his mind. "Get here, quickly!" Jason hurried down, crushed at the devastation he was seeing. Even though Camp Half-Blood was probably even worse, there was something he had felt about the indomitable strength of Camp Jupiter and the power of the legion at war. It felt like nothing could ever defeat New Rome. Hazel pulled him aside, and Octavian and Reyna joined. Jason felt a small twinge at seeing Reyna again, a slight twist of the heart, a gentle tugging of the mind, and he didn't look into her eyes.

"We really need you right now," Hazel said, her voice full of urgency. He saw pain in her eyes. "There's a–" Octavian butted in.

"There's a prophecy." Oh no, Jason thought. Not again. Octavian began reciting.

"Fulmina hostis infra terra–"

"Octavian." Reyna cut him off. "English please, not Latin."

"Fine," Octavian muttered. "Whatever the hell you say."

"Lightning's enemy under the earth

Shall once again reclaim and rebirth

War upon by dragon's breath

Once broken found through cage of death."

"Lightning has to be you," Hazel said. "And your enemy…" Everyone paused, trying to guess which enemy could create such war and destruction.

"It could be Typhon," Reyna said musingly. Jason found it so difficult to meet her impenetrable gaze, ever so deep. He hadn't felt this awkward before, so why now? "He breathes dragon fire, and Jupiter once defeated him with lightning bolts."

"Great," Jason muttered. "So now Typhon has apparently risen from Tartarus and I'm supposed to defeat him by striking him with lightning bolts like my dad did once."

"He can't have fully risen," Reyna said, her voice sharp. "Or else we'd all be dead under his furious storm. So he must be only part way, and we have to stop him before he really rises. According to Percy, Camp Half-Blood is being attacked even worse than we are, and they can't afford to send out anyone else. It'll have to be us." She clipped off every single of her words.

"It's too dangerous to go alone," Hazel said. "You'd never succeed." She paused. "Someone needs to go with him." Silence followed.

"I'll go." Reyna finally said.

"No!" Hazel yelped, her eyes wide. "We need you here. We can't spare you. We're getting attacked more and more frequently, and we won't have anyone to manage the attacks! You're the praetor of the legion!"

"Actually, you can," Reyna replied evenly, staring into Jason's eyes the whole time. Somehow, he managed to hold her gaze. "I can be trusted to go on the quest, yet the legion can still manage fine without me. Besides, doesn't the third line say something about war upon by dragon's breath? I'm the daughter of war. It would be most appropriate if I went." Jason understood what Hazel meant. He had to go. The prophecy said something about "lightning's enemy" and lightning was obviously him. But Reyna…she was praetor of New Rome. Camp Jupiter couldn't really afford to send out any of their best fighters. But maybe the real reason he didn't want to go with Reyna was because of what he had done to her, because of how he treated her. Jason wished he could've maybe done something more, to avoid everything being so awkward now. But that may have interfered with him and Piper's relationship, and interference with his girlfriend was the last thing Jason wanted.

"Fine then," Hazel sighed, interrupting Jason's thoughts. "I'll have the centurions see over the battle, and we'll have a temporary leader until…until further notice." It was an acknowledged fact. The chances they would make it back alive were as slim as the tip of a blade. If it really was Typhon, as Reyna predicted, then the chances were smaller than ever. Almost as small as the Prophecy of Seven, and there were seven demigods that time. This time there were only two, himself and Reyna.

Wishing Piper was here to help him, Jason said to Reyna,

"We should leave as quickly as possible. Let's arrange how we should start this quest, and get moving." Reyna nodded, her face as expressionless as it had been since he returned.

Suddenly a griffin leaped out of nowhere, slamming Jason on the ground. He tried to reach for his sword, but he was crushed under the weight of the griffin's paw. Sharp claws pierced into his skin, drawing blood. Before Jason had any time to plan a way to escape, the griffin had dropped dead beside him. He stared in stunned shock at Reyna's figure looming above him. Her sword dangled by her side, held in one hand.

"Well, are you just going to lie there for the rest of your life?"

Blood rushed to Jason's cheeks. He scrambled up, feeling slightly embarrassed. He'd forgotten how intimidating and powerful Reyna could be.

Talking with Reyna made him nervous now. He'd gone off with Piper, leaving her alone. He still trusted her the entire time, even though she had been leading the attack on Camp Half-Blood. But he just didn't feel the same way about her than Piper. Piper was so pretty, so…perfect. He missed being beside her. She always made him feel like he was floating in the clouds on a sunny summer day, while Reyna gave him the sensation of being struck by lightning in the middle of a pouring thunderstorm. (Yet deep down in his heart, Jason wondered which he truly preferred.)

"According to the prophecy, our best guess is Typhon. We should probably find an entrance to the Underworld, or possibly even…Tartarus," Reyna stated as they entered her cabin, sitting down by her desk. "But the problem is…how are we supposed to get there? We could try the Door of Orpheus and go through the Underworld." Jason groaned, dropping his head into his hands.

"This is really going to be the hardest quest ever," he said. "I could probably call Tempest to get us there. But don't we need music to get in?"

"Yes, we do need music," Reyna said, sounding slightly exasperated. Her words held an air of finality. "There should be a way to do it. We'll figure something out." Jason had more doubts, but he didn't want to say anything. Obviously Reyna wasn't willing to talk about it.

"But what exactly are we supposed to do when we get there? And isn't it pretty much impossible that we're going to get there without any obstacles?"

"I believe so. Since when has there ever been a quest without obstacles along the way?"

"Is there any other way we could find an entrance to Tartarus?" Jason asked, slightly doubtful that they could make it into the Doors of Orpheus if he and Reyna went alone–without music, if whatever plan Reyna had didn't work. He didn't voice his doubts to Reyna however.

"Not unless you want to go to a cave called Aornum that's situated in Greece."

"Uh…let's try the door first. And if that doesn't succeed, we turn back for the cave in Greece."

"All right then." Reyna stood up. "Well," she said, looking at him disapprovingly. "You'd better get ready."

The rain had progressed from a drizzle to droplets by the time Jason had gotten ready. Walking out, he found Reyna at the stables, brushing out Scipio's mane and tail. He watched her slim, skilled fingers getting out the tangles, stroking Skippy's neck. Jason let out a silent sigh. Reyna was just as powerful as he last remembered her, if not more so. But this was the gentler side of her that so few ever saw. He watched as she gently kissed Skippy's head.

"Protect the legion," he heard her whisper. "Keep them safe, and don't let anything happen to them. I'll try to come back as quickly as I can." Jason bit his lip. They probably weren't coming back. Not wanting to call out to Reyna, and ruin the inexplicable perfection of the moment, he slowly walked forward, entwining his fingers into Skippy's silky mane.

Without looking up, Reyna said quietly, "Let's go."

Hope you liked the present :) Updates may be a little slower because of projects and tests and exams and such...:P But I'll try to get one out every two weeks or so.

CC is greatly appreciated and flames are welcome.
