Perhaps Artemis has a prophecy in mind. There could be a prophecy that involves Percy and his role in the grand scheme of things. If Percy were to be killed or seriously harmed by Gabe, it would disrupt the prophecy. So, to ensure that the future unfolds as it should according to the prophecy, Artemis saves Percy from Gabe.
Maybe Artemis sees Percy's potential. Percy has shown great courage and skill in other situations, and Artemis might recognize that he could be an important asset in the future battles against the forces of evil. So, she decides to save him from Gabe, who is a nuisance and a threat to Percy.
In the fanfiction, Artemis might use her divine powers. Maybe she creates a distraction so that Percy can escape from Gabe. For example, she could make a sudden bright light or a loud noise that confuses Gabe, giving Percy the chance to run away.
In many fanfictions, the hunters would first assess the situation. If Percy is being held captive by Gabe, they may send in a stealthy member to find Percy's exact location. Once they know where he is, they would launch a coordinated attack. The hunters are known for their teamwork. They could surround Gabe's place, and some might engage Gabe directly while others free Percy. Their connection to nature might also give them an edge, like using the environment to their advantage during the rescue.
One possible plot could be that Artemis is captured by some powerful ancient enemy, like a primordial being. Percy, with his skills and courage, embarks on a quest to find her. He might face various challenges and monsters along the way. Maybe he has to solve some riddles related to the moon, as it's Artemis's domain. Finally, he locates Artemis and uses his water powers in a creative way to defeat the captor and free her.
In the fanfiction, Percy might use his powers over water to somehow rejuvenate Artemis. Maybe he discovers a magical spring that has the power to stop her from fading.
The Hunters of Artemis are very likely to show up. They are Artemis's loyal followers and would surely be involved in the search for their mistress. Annabeth could also be there. She's Percy's friend and has great wisdom, which could be useful in devising a plan to save Artemis. Grover might be another character. His ability to sense things could help in tracking Artemis or finding clues about her whereabouts.
One possible scenario is that the hunters disguise themselves as normal people and approach Gabe's place. When Gabe least expects it, they reveal their true identities and take him by surprise, saving Percy. Another could be that they use their tracking skills to find Percy's location even if Gabe has hidden him well.
Well, she could betray Percy by revealing his secrets to his enemies. Maybe she's forced to do so under some kind of magical compulsion or threat.
Well, in a 'percy is tortured by gabe fanfiction', it could be about Gabe using his position of power or some malicious means to make Percy's life miserable. Maybe Gabe is physically or psychologically torturing Percy. It could be set in the context of the original Percy - related universe, where Gabe is taking advantage of Percy's situation, like his being a demigod and having to keep it a secret. The writer might be exploring themes of power abuse, suffering, and how Percy overcomes or endures such a difficult situation.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might involve a story where Percy is subjected to abuse by Gabe within the context of the fan - created narrative, perhaps exploring themes of power, survival, and the character's response to such difficult situations.
It could be that Percy has been ostracized or misunderstood by the people he cares about. If his actions were misinterpreted and he was made to feel like an outcast, that might have led to his suicidal thoughts. Also, he might be suffering from some kind of prophecy or fate that seems inescapable, and he thinks death is the only way out.
