In the fanfiction, Percy might use his demigod senses. Since he has been in the casino before, he knows the layout and the tricks it plays. He could be searching for any signs of Nico's presence, like his unique demigod aura or any items that Nico might have left behind as he moved through the casino.
In this fanfiction, Percy could also rely on his friends or allies. He might have some sort of help from other demigods or even from the gods themselves. They could provide him with clues or abilities that would help him in his search. For example, a god could give him a special vision to see through the illusions in the casino and spot Nico more easily. Also, Percy's experience with dealing with difficult situations and his determination to save Nico would drive him to explore every nook and cranny of the Lotus Casino.
One challenge could be the time - warping effect of the casino. Time moves differently there, and Percy has to fight against getting caught up in it himself while trying to find Nico. Another might be the various distractions, like the all - you - can - eat buffets and the never - ending games that are designed to keep people inside.
I'm not sure specifically as it could be one of many fan - made stories. It might be a story where Nico, a character, does something to save Percy in the context of fanfiction. Fanfiction often takes existing characters and creates new, unique scenarios for them.
Well, first of all, AO3 is a great place to look. It has a very user - friendly search function. Just type in 'nico saves percy' in the search bar, and it will show you relevant stories if they exist. Another option is to check out some Percy Jackson - focused fan communities. Sometimes, fans share their works directly in these communities, or they can point you in the right direction to find the specific fanfiction you're looking for. Additionally, some Tumblr blogs dedicated to Percy Jackson fan works might also have links or mentions of such a fanfiction.
The camp leaders might betray them. If there is a power struggle within the camp, and Percy and Nico are seen as threats to the current leadership's power, the leaders could set them up. They could make it look like Percy and Nico are breaking camp rules or endangering the other campers, which would lead to the rest of the camp turning against them.
In some fanfictions, their relationship might develop because of a common enemy. The threat of this enemy forces them to put aside any differences and work together closely. As they do this, they start to see the good in each other. Nico might see Percy's leadership skills, and Percy might see Nico's hidden strength and loyalty. They gradually become closer friends or even something more, depending on the nature of the fanfiction.
Maybe a rogue demigod who has turned bad. This demigod has made a deal with some underworld forces and is using the Lotus Casino as a base to recruit more followers. They create all sorts of chaos in the casino, changing the rules of the games to suit their evil plans. Percy has to stop this demigod from spreading their influence further.
Well, they might use their combat skills. Percy, with his control over water, could create barriers or use water attacks against threats. Thalia, with her lightning powers, can strike down enemies. They could also use their strategic thinking, like leading Nico to safe places and standing guard over him while he rests or recovers his strength.
Annabeth could be a great addition. She can provide her strategic mind and wisdom. For example, when Percy and Nico are on a quest, she could stay back at the camp but offer advice through Iris - messages. And when they get stuck, her knowledge of architecture and mythology can help them find solutions.
Nico might be initially shocked. He could feel a deep sense of anger towards whoever was responsible for Percy's abuse. Then he would probably become very protective of Percy, vowing to keep him safe from any further harm.
One idea could be that Percy discovers a hidden passage in the Lotus Casino that leads to a different era of the casino, like the 1920s version filled with flapper - style gamblers. Another could be that he has to break a curse on some of the casino guests who have been trapped there for decades by a malevolent spirit. Maybe he teams up with a new demigod he meets in the casino, who has a special power related to chance, to outwit the casino's magical traps.
