"I'm warning you now, it's going to be a bumpy ride," Leo muttered as the golden shape began to appear on the horizon.

"What the bloody hell is that?!" Ron exclaimed, looking between Leo and the gradually growing shape.

"A dragon!" Hermione finally realised, before squinting her eyes. "A metal dragon..." Ron and Harry gripped their broomsticks tighter, glad they would be flying safely on those instead of the golden metal beast that was making it's way to land.

"I introduce you all to Festus!" Leo grinned, as the dragon beat it's wings a final time and landed heavily beside the lake.

"It has a name?" Whimpered Ron. Festus responded with a chorus of whirls and squeaks.

"It is infact a he," Leo explained, before running to Festus and throwing his arms around the creatures thick neck. "How're you buddy? How's cabin 9? Looks like they did a good job of you, but there's still a few tweaks I have to make..." Leo began throwing off questions which Festus answered in squeaks and creaks.

"He can speak to it?" Harry asked, turning slowly to the other demigods.

"Him" Piper corrected as the others nodded slowly.

"I'll fix him up in full once we hit water," Leo explained, trudging back over to the others. "He will be good to fly until then."

Hermione looked uncertainly at Ron, who kissed her forehead, well aware of her fear of flying and heights.

"You'll be alright," he assured. "Percy looks just as scared as you."

"Hey!" Percy cried in defense, but everyone could see his legs shaking the tiniest bit.

"Alright everyone, all aboard the Festus express-tus," Leo declared, walking towards the dragon who bent down so he could climb aboard. Leo pulled himself up to sit just behind Festus' head on his neck, then began to help Hermione up, followed by Piper, then Annabeth and finally Percy.

"I can't wait until we hit water," Percy stampeded, watching the lake with envious eyes. On either side of Festus, Harry and Ron mounted their broomsticks and flew up into the air, waiting for the others a few meters up.

"Alright, here we go!" Leo warned, placing his hand gently on Festus' neck, causing the dragon to flap it's wings and push off the ground. At the back, Percy gripped tightly onto Annabeth waist and held back a cry. Hermione glaced towards Ron, who was hovering high and wide enough to not be knocked back by the pounding of Festus' wings, and he flashed her a reassuring smile. Then Festus feet left the ground and Hermione burrowed her head into Leo's back, squeezing her eyes shut.

Then they were all airborne, rocketing through the early crisp morning sky.

With wind whizzing past Leo's ears, Hermione's and Percy's chorusing whimpers were almost inaudible. The sun was shining on his face and Festus was grinding beneath his hands. He had missed traveling in this fashion, meters in the air at insane speeds on the back of his own creation.

However there was only so many hours Leo could send basking in the sun and enjoying the pleasant breeze ruffling his hair, before his mind began to wander.

Calypso.

Calypso.

Calypso.

The others had tried to explain Calypso to Leo.

She was the daughter of two titans, being Atlas and Tethys and had been forsaken to life on the isolated island of Ogygia. Percy had enlightened Leo of the fact, that when he was 14, Percy had washed up on Calypso's island where she nursed him back to health, before he left the island. He then went on to tell Leo, that he too had been washed up on Ogygia after being blasted from the Argo II.

How Leo didn't remember that, he wasn't quite sure.

The others had insisted that Leo had spoken of her regularly and had always been working to find a way to save her from Ogygia, as after you go to the island once, you can never return. However, with the sudden invitation to Hogwarts, they had all failed to notice Leo's sudden lack of Calypso mentioning.

Percy had also come close to mentioning something else about Leo and Calypso, but Piper had cut him short with a quick glance towards Luna, who had joined them in the conversation. What that mean't, Leo still wasn't so sure.

Festus swooped right suddenly, to avoid Ron who had moved into the dragons path by accident. Hermione squealed and dug her nails into Leo's shoulders, as Ron yelled back a quick apology over the wind.

As quickly as it had been distracted, Leo's mind returned to Calypso. Who was she? Why had he forgotten her? How had he forgotten her? And most importantly, how would he, the son of fire, find her again?

By the time Festus set down on sand, it was late afternoon, and the sky was beginning to turn the pink of dusk.

The group had settled in a small, isolated cove, where only 8 meters of sand separated ocean from the 100 meter high, rock wall.

"We'll be safe here for the night," Leo insisted, jumping down from Festus. Percy was close behind.

"Thank Posideon!" He cried, before sprinting into the water and diving beneath the waves, clearly thankful to finally be in his own element.

"What happens if a human looks down and sees us?" Hermione asked, beckoning upwards to the tip of the looming cliff edge. "Or you know, sees the giant metal dragon?"

"The mist will cover us up," Annabeth explained, "Festus will just look like a car or something."

"But how do we explain getting a car down here?" Hermione continued.

"We'll cross that bridge when we get to it," Annabeth shrugged as Ron and Harry touched down. Immediately Ron collapsed into the soft white sand.

"Can't- feel- legs," he moaned over dramatically. Hermione rolled her eyes and strutted over to him, pulling his broomstick out from between his legs.

"So, what's the go now?" Harry asked, letting his own broomstick fall to the ground beside Ron. "And where's Percy?"
Right on cue, a mop of dripping black hair broke the surface of the water, and Percy appeared, before he dived head over heels back into the deep blue. Annabeth sighed, and exchanged a mutually embarrassed look with Hermione, who was sitting in the sand with Ron's head in her lap.

"Now, we spend the night here. There's a small village at the top of the cliff, so we can collect some supplies. By tomorrow morning transport will arrive."

"What transport?" Harry asked, as Percy again broke the surface, before coming splashing out of the water, up the bank and back to the group.

"Cabin 9's got a ship ready for us. Or a boat. Nothing fancy unfortunately," Leo explained.

"I heard you mention cabin 9 earlier, what exactly is it?" Hermione asked.

The demigods exchanged a glance.

"Well at camp, there's a cabin for each god or goddess," Piper began.

"And the cabin is the home of all the gods or goddess' kids," Leo continued.

"So cabin 9 is full of your brothers and sisters?" Hermione asked.

"Yes."

"Boys and girls get to stay in the same cabin?!" Ron exclaimed. "What if-"

"Ron!" Screeched Hermione, slapping him across the ear. "They're all siblings you idiot!"

"Anyways, Cabin 9 fixed up the best boat they could find, and Percy made a deal with his dad to send it sailing this way. You will all be good to sail "the road to Rome" by tomorrow," Leo continued, before continuing after a deep sigh. "While Festus and I," he patted the dragons neck, "hunt this Calypso chick."

Leo couldn't help but notice Percy bite his lip and Annabeth and Pipers glance with the mention of Calypso.

There was only an hour or so until night fall, so the group set to work prepping for the night. Harry suggested setting up this magical 'bigger on the inside' pop up tent he had carted along, but the tent wouldn't be hidden by the mist if anyone was to look down the side of the cliff. Plus tents, even the magical kind, had no chance of staying standing in the heavy wind that was casting off the ocean.

In the end, the group settled for a small rock cave further down the cove. They were all able to fit inside and Festus even had a tuck away hiding spot at the back, because at the end of the day, spotting a car at the bottom of a 100 meter drop was just as odd as a giant metal dragon.

While Harry and Ron took a trip on their broomsticks up to the top of the cliff to gather supplies, the rest began shoveling sand into the cave to act as a bit of cushioning on the hard stone floor.

"I've always wanted to go camping," Percy laughed.

"You literally live at a place called CAMP half blood," Piper replied. Percy shrugged.

"It's not the same."

Once the sun had fully set, Leo lit of ball of fire, which hung in the air in the center of the cave. There wasn't any pieces of wood or branches in the cove so the floating fire had to do.

Not long after, Harry and Ron soared back down with plastic bags filled with food and bottled water.

"Muggles are so strange," Ron declared, the second they stepped into the cave. "How the photos are all so still and glum, and food comes in weird packets, like this!" He retrieved a pink bag from the larger plastic one, and held it up. "Mars-ma-lows" he read. "What even is that? Sounds like a vegetable."

"Marshmallow," Hermione corrected, snatching the bag from Ron's outstretched hand.

Dinner that night was 2 minute noodles cooked with water boiled personally by Leo, followed up by roasted marshmallows, which Ron realized weren't actually vegetables before eating basically the entire 3 bags.

"Reckon if I ask the elves at Hogwarts to start serving 'Marve-mals' they will?" Ron asked, looking around for another bag of the sweet treats.

"Should we iris message Jason?" Piper question, ignoring Ron. Percy smirked her way in response, and Leo made kissy noises, causing Piper to blush beetroot. "And Hazel and Frank," she continued, "to let them know that we're only a few days away?"

Annabeth smiled sympathetically at Piper before revealing a golden drachma from her pocket, "We also should probably ask if they found out what the spontaneous hell hound attack at their camp was all about the other day." Annabeth suggested. "So Percy, Harry, get to it."

Percy flicked his wrist towards an open bottle of the drinking water standing next to Hermione. Slowly it began to pile out to form a large floating sheet in the center of the group, hanging just bellow Leo's floating fire orb.

"Lumos," Harry flicked his wand, and the white light shone from the tip into the water, casting a rainbow. Immediately, Annabeth threw the drachma into the rainbow mist.

"Oh Iris, goddess of the Rainbow, please accept my offering. Jason Grace, Camp Jupiter."

Screaming flooded the cave.

"Jason!" Cried Piper in pure panic.

Before them, through the misty iris message, Jason Grace was lying in a puddle of blood.
