Nico
A/N: So I'm pretty sure this is going to be the biggest feels –breaker of the lot. I really don't know how this one will play out. But I can't skip Nico so her goes nothing
Fine. IF YOU WON'T PROTECT YOUR OWN SON THEN I GUESS I WILL.
Nico was not having a good day. Actually that was a bit of an understatement. Nico was having an absolutely horrific day. While his friends were in Greece fighting the giants, he was at Camp Half Blood, fighting the Romans. This wouldn't be so bad, but he was extremely worried about what was going on in Greece. Nico was concentrating extremely hard on his friends, trying to sense if they were still alive. It was hard to do while fighting. The other issue he was having was the small factor of fourteen gods speaking in his head. Nico had no clue how this happened, but it was really damn annoying. He knew the gods could project thoughts into the minds of a mortal, but he didn't understand how all of them could be projecting thoughts into his mind at once. He figured that it might help him a bit. Surely, if the gods were projecting thoughts to him, they could understand what he was thinking. So, he thought as hard as he could at the gods to help him protect their children, both the ones that were in Greece and the ones fighting alongside Nico. Thoughts came flooding into his head, the gods agreeing to protect their children. Relief flooded through Nico, but it was short lived. He saw Will Solace fighting one of the Romans – a child of Mars. They were fighting with swords, and it was clear that Will was struggling. Nico wasn't sure why, but he was extremely fond of the son of Apollo, and he really didn't think he could take it if something happened to him. Nico could see the uncertainty on the face of the blond boy. He wouldn't hold out much longer. So, Nico prayed to Apollo to protect his child. When he got a response, he was enraged. He understood that Apollo was fighting the giants, but couldn't he just help Nico out a little? Apparently not. Frustrated, Nico said aloud, 'Fine. IF YOU WON'T PROTECT YOUR OWN SON THEN I GUESS I WILL.'
It happened in a matter of seconds. Nico saw the blade heading straight for Will's heart and then he was in front of Will, and the blade was heading for his heart instead. He had no time to bring his sword up to meet the one that would kill him. If Nico had bothered to listen to Reyna, he would have had armour on. But considering he just jumped straight into the fight, he didn't have so much as a helmet. In the millisecond before the blade pierced his skin, Nico looked at Will and he realised that he had finally been accepted and now he was going to die. And then he was in agony. The imperial gold sword went through his heart and it stopped almost immediately. Nico di Angelo, son of Hades was dead.
Line break
Nico opened his eyes and saw Will leaning over a body, trying to see if he could help the person. 'Odd,' he thought, 'I could've sworn I died.' The minutes before his death flashed through his mind, confirming that he had died. Nico looked down at himself and was startled by what he saw. He was transparent. Nico had always been pale, but now he was literally transparent. 'I'm a ghost?' he thought to himself. 'What the Hades? Ghosts can't just randomly appear, they need to be summoned.' He looked around, as if searching for an answer, and jumped when he saw his father standing next to him. 'Dad? What is going on?'
'Nico, I'm so sorry. I tried to protect you, but you willingly sacrificed yourself. I can't protect you if you sacrifice yourself.'
'That's not what I'm asking. I'm asking how the Hades I can appear here without being summoned?'
'Well you are my son. The most powerful of my children for almost 1000 years. You appear to have somehow tied your spirit to the camp, so you can appear here without summons occasionally.'
'What does occasionally mean?'
'I'd say about once a year or so.'
'Can anyone see me?'
'Those who were close to you will be able to see you.' That is when Nico realised that it wasn't just because he was a child of Hades, it was because his father had allowed it to happen.
'Thank you, father.'
'You're welcome. Now come, Elysium awaits you.'
And so, Nico di Angelo parted the world of the living. But he would always be there when his friends needed him. Or when a new demigod had trouble fitting in. It turns out, Hades wasn't quite right when he said Nico would be allowed back once a year. He came back whenever he was needed.
