Auli'i Palakiko was a surfer and marine biologist living on Hilo, Hawai'i. She loved the ocean, waves, the creatures that she saw on an almost every day occasion. Auli'i went out on the ocean almost every day after she got off of work, loving her hobby more than her job. Being a surfer, especially a hopeful-professional surfer, got incredibly dangerous at times. This had been proven to her one day when she was out and a harsh wave sent her board capsizing into shark-infested waters and threw her under. Auli'i would have died if she hadn't made eye contact with one of the majestic creatures, her only thought being how incredibly human-like his eyes were before she blacked out.
Auli'i woke up in the next few hours on the beach, a well-dressed, beautiful man peering over her to check if she was awake. Auli'i reacted like any well-meaning woman would - By freaking out. This man may have seemed familiar when she peered into his eyes, but to Auli'i, he also seemed very, very creepy just staring at her like that! Though, after the initial freak-out, she asked for his name and he replied - Alex. She thanked him for saving her life, unable to get rid of the itching feeling that he was incredibly familiar. But it was a mystery lost to the ages. That was until a couple years later, when the two happened to cross paths again.
Auli'i, at this point, had followed her dream of being a professional surfer. She had been to many different competitions around the world, and when she had caught up with Alex once more, it was in Sydney, Australia that he walked up to Auli'i once more, offering her a round of drinks if she won. She did win, and the two drank the night away. Auli'i left the next morning to return home, with an unwitting surprise on her hands.
Uselo was born nine months later, in the town of Waikoloa, just on the other side of a nearby volcano from Hilo, where Auli'i had moved after abandoning her job as a marine biologist. She hadn't realised she had gotten pregnant until about three months, but instead of being scared, Auli'i was happy to be welcoming another life. In response to the news, she had lined up a job in her town using her marine biologist skills.
When Uselo was born, the town came to celebrate together. There were many gifts, including one from an outsider - Alex. The man who had impregnated her, in a letter, had revealed that he was not who he seemed. He told her his real identity was Palaemon, the Greek God of Sharks and protector of Sailors. Along with his explanation, he had included a small bronze necklace with the letter - "For my newfound son - He'll need it when his time comes."
Uselo was raised with his mother trying her very best. He was taught to swim and surf from a young age, and was close with a lot of his neighbors, including the Akana family, who had kids around his age, and a father who always helped Auli'i out when she needed it, and vice versa when he did. As they grew up, the three children grew close, but far apart. The Akana twins always went up to the volcano, Mauna Loa, but Uselo preferred the ocean to anything. As a result, the trio ended up never talking very much.
Uselo didn't know it, but when he turned 13, his life would take a weird turn. A Telekhine emerged from the ocean while Uselo's back was turned. He managed to barely notice, and turn around just has the necklace he had just pulled off was transformed before his eyes into a Celestial Bronze halberd and stabbed the Telekhine right through. It wasn't just a weird ocean-creature either. In the next few months, without telling anyone, he had been attacked by some unusual large-looking dogs as well. It wasn't until he had been caught off guard by both a Telekhine and a Hellhound at the same time, and came out with a couple of scratches. Uselo told his mother, and Auli'i freaked out. To her, the best course of action was to simply relocate again - Back to Hilo. She got her old job back, and Uselo was kept safe.
When Uselo turned 16, a tragedy struck. Waikoloa was given a Volcano warning, but it wasn't saved in time. They had received the news of everyone's death within the day. Uselo and Auli'i were devastated. That was, until he caught glimpse of the Akana twins. He meant to go speak to them, but had realised it was too late when a man had sent them on a plane to New York City. Uselo spoke to the man - Joshua. Joshua had asked him if he had seen any strange creatures, and after confirming it, had revealed himself as a Satyr. He explained that the Akana twins were being sent to Camp Half Blood, a place for Demigods and goddesses. After speaking to his mother, Uselo had followed them.
