Turning over in his bed, eyelids flickering, Harry slept soundly. A spacey and strangely melodic voice whispered in his ears. "Hello Harry Potter. Son of Lily and James Potter, Child of the Lord of the Underworld." Fading in and out of sight, a small girl with scraggly white-blonde hair smiled serenely. She flitted about like a wisp of smoke, and just hummed, swaying to music only she could hear. "We'll meet each other soon, Mummy Artemis told me. Well, part of her did. She's the Virgin Goddess, you know. Patron Uncle Apollo promised me a friend. I hope you agree." She informed him calmly, unfazed by the oddness of the situation. "Erm, yeah. I'd like that. But what do I call you?" He asked. Her large grey eyes widened even more so, and her smile grew. "Oh. My name is Luna Celeste Lovegood. Daughter of Artemis, Champion of Apollo."

Groaning, Harry rubbed his eyes and stared at the room in confusion. He was in the new Hades cabin, but something was different. Oh. He thought blankly. There were gold inscriptions strung across the top of the walls. Like a pattern of flowers, the words wove into intricate designs. The words Founder: Harry Potter, Son of Hades, were followed by a string of other names, such as Dan, Annabeth, Percy, Jake Mason, Charles Beckendorf, and Silena.

Must've been Dad. Harry mused absently. His brow furrowed, and he scrambled to remember his dream. "Daughter of Artemis, Champion of Apollo?" He asked the empty room. "Lady Artemis has a daughter?" A voice questioned in shock. Turning to the door, Harry saw the surprised look on Dan's face as he entered. Harry nodded, and scooted to the side so his best friend could sit next to him. "You know some odd people, little dude."

Harry laughed, and smiled at the older boy. "Well, shrimp, I got you a present." Harry's face held shock, and his eyes lit up in eagerness. Dan grinned, and handed him a carefully wrapped box. Harry just stared, taking it shakily. Dan frowned for a second, before he put a smile back on his face and watch as his little brother gingerly opened the present. A gasp of wonder made him smile softly.

A picture frame looked out from a box, with a carved hellhound and stag on either side of the frame. The picture was of Harry and Dan wrestling playfully, while Annabeth laughed in the background, and Luke snuck up on her with a bucket of water in his hands. The word Family flowed across the bottom of the frame. Harry's eyes misted over, and he hugged Dan tightly, whispering thank yous over and over. Dan just hugged him back, holding the boy securely to him and softly carding his hands through his hair.

From the outside, it was obvious who the cabin belonged to. Dark and intimidating, the cabin looked like it had been built by Hades himself. On the inside, however, it was ridiculously beautiful. With deep velvety green sheets and blankets, mahogany wooden floors, delicately-made furniture, deep almost-burgundy red pillows, and various shades of welcome blacks and greys, the place was extraordinary. Drapes kept the individual beds private, with elegant wardrobes and chests. Although this wing of the building was exclusively for the children of Hades, the bed next to Harry's had a sign pinned to it with a Greek Eta and a flame. As it hadn't been there the night before, Harry could only assume it was from his father.

"It's a Greek H," Dan offered. "My dad uses it in his designs." Harry's eyes widened, and he whispered a quiet thanks to his father. "He's allowing you to stay in here, my dad, I mean." Harry hesitated. "If you want, that is."

Dan's eyebrows shot up behind his fringe. "I'll be right back." He said, before he raced out of the cabin. Ten minutes later, he was back, out of breath, and with a duffle bag. Harry watched in surprise at the speed the brunette unpacked his belongings, watching as he raced into the bathroom to put away his toothbrush and straightener, before practically flying to his newly claimed bed. Collapsing onto it, Dan groaned and shot Harry a glare as the 10- year-old muffled a giggle. Neither boy noticed the dark glow that surrounded two beds on the opposite wall. Nor did they notice the two names carved into the beds as the glow receded.

"Hi." Harry waved shyly. A couple days after the cabin had finished, the children of minor gods started to move into the second wing of the cabin. It was a general cabin for "Underworld children" like Hecate, Morpheus, and Hypnos. A couple Iris kids had moved in as well, and it was obvious that the kids were all relieved to find comfortable bunk beds. Harry winced in sympathy, the floor of the Hermes cabin wasn't comfortable. He had passed a Hecate girl in the shared common room between the two wings, and had decided to stop by the other wing when he saw her.

A few kids flashed smiles at him, while other just waved and didn't look up. "Hi Harry!" Chirped a small raven haired Latina girl. "I'm Zaire. Daughter and sometimes Son of Melinoe. Don't worry, I don't bite! Well, not people I like." She said cheerily.

"Sometimes son?" Harry asked curiously. "I'm genderfluid. I'm a she right now. But if I have my hair gathered under a beanie, I'm using he pronouns." Harry nodded thoughtfully. "Oh!" She squeaked, looking behind him. "Dannon!" Dannon? The yogurt? Harry wondered, as the girl shot past him. "Oof!" Came from behind him. "Dan!" Harry exclaimed. "Wait, you're Dannon?"

Dan nodded embarrassedly, "Yeah. I see you've met Zaire-bear. I ran into her when I was 10, she was just an itty bitty kindergartener. She was being attacked and summoned a ghost, I was there seeing my mom, and helped her out. I brought her to camp, gods, 5 years ago. But she's been away at her dad's for a while. I've been meaning to introduce you guys."

Jealousy pooled in Harry's stomach, but he nodded. Maybe she could be family too? After all, Dan was family and he obviously cared about her. "Ok." He said. Little did he know that he'd just saved lives with that decision.

"So, Zaire." He started awkwardly. "Did you notice Dan's sad dimple?"

"Hello again, Harry." Luna said dreamily. Swaying, she stared at a small pixie-like creature. "These are Nargles. They're endangered, but they like mistletoe." Harry tilted his head at the fairy. "Luna? Are Fae real? I know satyrs, nymphs, and centaurs are, and pixies, but what about the Sidhe and elves? Or a sprite or a dwarf? What about a- a kitsune!" Harry asked, listing mythological creatures he'd read about. At the Dursleys' he used to sneak out to the library and curl up with a fiction book in a comfy chair. So he knew a long list of creatures from myths and stories.

"Some of them are. Some are extinct." She said sadly, her dreamy aura fading slightly. "My daddy is a 6th elvin. It's stronger in me though. Patron Apollo said that the elves chose me as kin. Daddy was too human." Luna said breezily. "Will you dance with me, Harry?" She asked suddenly.

"I don't know how to dance." He replied, embarrassed. "That's okay. Just go with what feels natural." Luna told him, twirling in the mist. She grabbed his hand and pulled him with her, and he laughed. They danced and played, laughing and telling jokes.

"I'd like to see you again, Harry. You'll be off to Hogwarts soon, I'd like to see you before you go to school. I'll be in the year behind you." She said, sitting next to him on a bench that appeared.

"Okay."

"Tell Daniel he should go with you. He's fifteen, I'm sure he could work for Daddy or Madam Rosemerta. Also, ask your father if you can take the name di Angelo. He will know what I mean." She said.

"Luna?"

"Stop by soon, Harry."

Almost a whole year had passed. He'd asked his dad about the name di Angelo, but had been told it was too soon. Percy, Annabeth, and Harry's Cyclops friend Tyson, had gone to search for the Golden Fleece, and save Grover. At the beginning, Dan and Harry had almost gone with them, but after Zaire and Dan's friend Phil, an older teen, had tried to tag along, they'd decided to stay at camp. It was absolute torture, as the new camp activities director was Tantalus, who held a particular nasty grudge against Hades and his children for his torture in the Fields of Punishment.

Percy had Iris Messaged them the whole story as they escaped to save Grover. Although Clarisse had been officially chosen for the quest, the trio had escaped the camp to help Grover themselves, and find the fleece to save Thalia's pine. Percy had been adamant that it was Ethan Nakamura who had poisoned the tree, which weakened the barrier as a result. Monsters had been getting in, and Harry had new scars and had gained light muscles as a result. In the end, they Golden Fleece had been found and Grover had been rescued from Polyphemus. Harry had been hard pressed not to laugh when he found out how the satyr had fooled the blind Cyclops.

"Harry!" Dan panted, having run to reach him. "They're back." Clarisse had arrived first with the fleece, but the duo had been waiting for Percy, Annabeth, and Tyson.

At that exact moment, a glow began emitting from Thalia's pine tree, and an owl soared towards Harry, a letter attached to its leg.
