His family history - His grandma was a daughter of Athena and was a luckily demigod who survived into adulthood. She moved to England and met a mortal, never revealing her demigod side again. So, she had a child and bladdy bla bla... Everything was good. Her daughter was mostly Mortal, with only demigod blood running through and no powers - the only thing she inherited from her mother was her wits. So Lorcans mother grows up in Ireland and becomes a Nurse which therefore attracts the attention of the GOD of medicine - Apollo. Apollo doesn't just fall for every nurse, doctor or paramedic. Lorcan mother was b e u t iful, and single. So one day, when Lorcans mother is out on a job, a particularly stressful situation involving a bus being spun off the road and hanging over a cliff. No one in the hospital that day had volunteered to help the paramedics so Lorcans mother agreed to go. Anyway, she dives into action, stitching up the wounds of passengers and saving being trapped inside. One of the passengers was a disguised Apollo who was in Ireland at the time, checking out some Irish folk music and poetry. He was mesmerized by her bravery and intelligence and naturally like mortals and gods go... Yes, you guessed it they had a child. So, Apollo runs off and all that, and Lorcan is born nine months later. Hmmm... things don't go so smoothly after that. Lorcan grandmother and grandfather die of natural causes and the family move to America for a fresh start. His Grandmothers demigod legacy is passed down a generation (skipping his mother) making Lorcan a legacy of Athena and a child of Apollo. But he doesn't get any powers from his grandmother.
Childhood - From a young age it was clear wasn't a normal kid, for starters, he had a odd fascination with medicine and would enjoy doctors visits, hospital and any injury he would acquire. He had a natural accuracy for basketball, archery or any sport involving skill. Yet, if he tried to play football or sports like it, he would fail miserably. He considered himself a nerd, he enjoyed comics, and was hated by most at the various schools he went to and got expelled from. Right, that brings us to another problem. Lorcan could not avoid trouble. He didn't make trouble. He didn't cause it either. Trouble seemed to follow him. Weird things happened. Like once he was called a freak by a TEACHER because a boy in his class slipped and Lorcan healed it as if by magic. Yes, weird stuff. Of course, his mother knew what was up but kept it secret and let him off the hook for any understandable trouble because, it really wasn't his fault. Anyway enough about his tragic bullying, trouble following all that I think you get the picture.
Finding his powers/ getting to camp etc - To be honest, all his life Lorcan thought he was a freak, freakishly smart at random things, mythology, ancient Greek, medicine, strategy. Yet it was still a surprise when he found a dracanae in the boot of his mother's car. He knew what it was, from his extensive knowledge of mythology but he had no weapon that could do any damage - he didn't know what could kill this thing! So naturally like a sane person would, he panicked. He had absolutely no clue where he could find something to slay a dracanae in New York. Well, he didn't know Olympus was floating above New York at the time. So back to the action. A dracanae was about to kill him, when bam! He finds the old dagger his grandmother had left to him in her will and to think he thought it was worthless before. She must of known all along about his powers. So that worked out well. Unlike however the battle... Lorcan was completely inexperienced in using weaponry especially against mythical monsters that were faster, stronger and more powerful than you. If it wasn't for his quick wit, he would of died for sure. He dodges blow after blow and finally manages to stab the beast in its shoulder only wounding it. It continues to attack him and only then does his mother return from work and find her son fighting a creature shed only ever heard about in school (she had the sight, and Apollo didn't tell her much about the monsters when explaining Greek mythology). Anyway because his mother was as quick minded as he was they managed to work as a team to trick and eventually kill the monster. But even though the dracanae was dead - so was his mother. When Lorcan had moved in to stab the monster after a quick distraction from his mother it had recoiled and killed her before Lorcan to get to it. After that, he needed answers and he needed his mother back. Only she knew what he was and she was dead. He was only 13. So he decides to wander - he had no family and no home. Not even friends that could let him sleep on their couch. He was alone and scared - what if more monsters came for him?
And they did. He wandered the streets alone at night, his problems not just food, water and shelter like any other runaway. No he got the blood thirsty and lethal monsters too. He spent months of hardship lost and petrified alone often on the middle of nowhere just anywhere that would offer him protection or a hiding spot from the monsters. But things aren't that was for ever, he starts creating cover for himself, realizing the monsters are attracted to something about him - his scent? He concentrates, becomes better and batter in battle - not perfect but not the inexperienced, clumsy klutz he used to be. He began disguising himself by hanging around with mortals to disguise his demigod scent. It didn't repel the monsters completely but it came at bay long enough for him to think, to plan and to find something that explained what he was.
He used his age to get pity from people, they gave him food, water and shelter - for a while but as soon as they started asking questions about him, well... He ran. Before they handed him into the 'the authorites'. He gained a bow from a rogue trader (a demigod child of hermes who'd grown up) that could shoot arrows with celestrial bronze - which helped. However, two demigods in a small area quickly attracted many dangerous monsters, and Lorcans aliiance quickly ended with his new friend, the poor son or Hermes died without even telling Lorcan his name or anything about camp.
Over time, he learnt the monsters weaknesses, their strengths and used it in battle. He began improving his cover. And following them. And eventually after nearly six months homeless, he was close to giving up, he didn't want to spend his life being hunted by monsters. He wanted real friends not just the homeless he hundreds around with to hide his scent. Luckily, one god took pity on him, Hestia, goodness of the hearth. He found her by a campfire, bearing the image of a young girl. She was quite vague but told him about Camp but not much else only that Greek mythology was real (which he had already sort of guessed because he recognized the monsters from his mythology books). She gave him directions and he eventually made it to camp at age 14.
