A good plot could be that a rift between dimensions opens up and Percy Jackson is pulled into the Warcraft world. Sylvanas, upon seeing him, thinks he could be the key to some ancient power she's seeking. Percy has to figure out how to deal with Sylvanas' schemes while also learning about the new world he's in. Maybe he teams up with some of the more benevolent Warcraft races to stop Sylvanas if she becomes too power - hungry.
For a fanfiction plot, imagine Percy Jackson arrives in the Warcraft world during a time of great turmoil. Sylvanas, seeing his unique abilities, wants to recruit him for her own army. But Percy refuses as he doesn't want to be part of her power - play. Instead, he sets out on his own journey to understand this new world and find a way home. Along the way, he crosses paths with Sylvanas multiple times. Each encounter changes their relationship, from distrust to a strange kind of respect as Percy shows his strength and moral compass in the face of the Warcraft's complex and often dark situations.
In a Percy Jackson and Sylvanas Warcraft fanfiction, Sylvanas might view Percy as a potential ally or threat. Given Percy's demigod status in his own world, his powers could be on a different scale compared to the denizens of Warcraft. The story could revolve around how Percy adapts to the Warcraft setting, its magic, and politics, all while Sylvanas is watching his every move, perhaps with an ulterior motive.
One great Percy Jackson Warcraft fanfiction is 'The Demigod in Azeroth'. It has an interesting plot where Percy is transported to the Warcraft universe and has to use his demigod powers in a whole new world full of different races and magic systems.
Another theme is the idea of an outsider trying to fit in. Percy is an outsider in the Warcraft world, and many fanfictions focus on his journey to find acceptance among the various races like the orcs, humans, and elves. It's about him learning the new rules and cultures while still holding on to his own identity.
Well, you could start with a portal that connects the Percy Jackson universe and the Warcraft universe. Sylvanus, being a powerful entity in the Warcraft world, could be interested in the unique powers that Percy has. In a fanfiction, Percy might be on a quest in his own world and accidentally stumble through the portal. Sylvanus could see him as a potential ally or threat. He could then team up with some of the more nature - friendly races in Warcraft, like the night elves, due to his connection with Sylvanus, who also has a connection to nature. They could fight against common enemies, such as the Burning Legion.
Well, it could vary a great deal. Some fanfictions might focus on Percy leading a new group of demigods in a resistance against an emerging threat, perhaps a new and more powerful enemy than the Titans or Giants. Maybe it involves a fight against a corrupt part of the Olympian council. It really depends on the creativity of the fanfic author.
One great Kronos fanfiction could be about his backstory before he turned evil. Maybe it explores his relationship with the other Titans and what led him to start the war against the Olympians.
Well, it depends on what you like. Some people might think it's great because it combines the world of Percy Jackson with gaming elements, which can be really interesting. It might offer a fresh take on the familiar Percy Jackson universe.
A plot could be that Kronos was once a good god but was corrupted by an ancient evil force. Through a series of events in the fanfiction, Percy and his gang find a way to cleanse Kronos of this corruption. Kronos then, in his redeemed state, helps them fight against the remaining threats to the world of demigods. He could use his knowledge of the old times and his powers to aid in battles and also offer wisdom to the young heroes.
One plot idea could be that Percy, being a son of Poseidon, discovers he has Dragonborn abilities. He could use his water - controlling powers in combination with the Dragonborn's shouts. For example, he might use a frost shout while manipulating water to create icy spikes. Another idea is that Percy has to go on a quest in the world of Skyrim to find a magical artifact that can save both his world and the world of the Dragonborn from an ancient evil that threatens to destroy both realms.
One possible plot could be that the entire Greek pantheon is thrown into chaos. Percy might be seen as a huge threat, and other gods and goddesses would either try to hunt him down or form alliances with him out of fear or a desire for power. Demigods would be forced to take sides, leading to massive battles among them.
