Summary
When Nico summons skeletons, they are connected to him via little threads of life, and they eat at his energy until he releases them. Nico often forgets to send the dead back, so they use his energy up to a dangerous level, and then he just faints/sleeps on the floor until it becomes normal. Will and the others are not amused.

Percy's never slept easy, and while back in New York he had to stay in his room, in Camp Half-Blood, his father's domain is only a few yards away

Summary
Athena campers (especially Annabeth) don't spar if they don't have to once they've got the proper muscle memory down. They learn more from watching and analyzing other campers' fights instead of making their own mistakes. They also know every single pressure point on the human body, and can get someone temporarily paralyzed in under 10 minutes.
Will also has this headcanon because he's a doctor and has the respect of the entire camp

Touch-Starved Trio by Creative_Stories
Fandoms: Percy Jackson and the Olympians & Related Fandoms - All Media Types
12 May 2026
Tags
Summary
Percy, Nico, and Leo are all incredibly touch-starved; they just have different ways of approaching it.
Percy loves any sort of playing with his hair, melts into the affection, whines if it’s taken away
Nico either silently demands affection, literally grabbing on and refusing to let go, or snarks off and is an absolute asshole until he gets what he wants.
Leo will keep working himself until somebody physically turns him away from the work and commands him to rest, and then he just shuts down into half-aware mode.

Summary
Annabeth has always liked bonfire night.
She likes hanging out with her siblings and laughing with her friends and eating smores.
However, she doesn't like the loudness of it.
Loud noises seem to make her brain spin, and as a child of Athena who's been on quests, that isn't an option.
She finds her work-arounds, and maybe, she finds that she doesn't have to work through issues alone.

Summary
Leo Valdez would like everyone to know that he is perfectly capable of taking care of himself.

Jason thinks he's exaggerating.
Piper knows better.
And Leo is about to prove a point.
