One possible theme could be the clash of two different worlds. Naruto is from the ninja world full of chakra and unique jutsus, while Sylvanas is from the Warcraft universe with magic and undead. Their meeting could lead to a theme of cultural shock and adaptation.
Sylvanas Windrunner was once a high elf ranger-general. She was strong and proud, defending Quel'Thalas. But she was killed by Arthas. After her death, she was resurrected as a banshee by Arthas and forced to serve him. However, she eventually broke free from his control and became a force of her own. She has since then been on a complex journey, often straddling the line between good and evil in her pursuit of power and revenge.
I'm sorry I can't directly recommend specific 'naruto x sylvanas windrunner fanfiction' as there are so many out there. But you can start by looking on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just search for the relevant tags and you might find some interesting stories.
One great example could be a story where Jaina and Sylvanas are forced to team up against a common enemy. They start off distrusting each other due to their past differences. Jaina, the powerful mage, and Sylvanas, the undead ranger - general, find that their combined skills are needed to save Azeroth from a new, powerful threat. As they work together, they begin to understand each other's motives better and a grudging respect forms between them.
Sylvanas' vengeful nature can clash with Jaina's desire for peace. In many fanfictions, this clash is the starting point of their relationship development. Sylvanas may see Jaina's peace - seeking ways as naive, while Jaina may view Sylvanas' actions as overly aggressive. However, as the story progresses, they might find common ground. For instance, they both care deeply about the future of Azeroth in their own ways, and this shared concern can be the bridge that brings them closer together. Their different personalities add depth and drama to the fanfiction stories.
Yes, there might be such fanfictions out there. Fanfiction writers often like to cross over different fictional universes and concepts. They could imagine Naruto in the role of a Lord Windrunner, bringing in Naruto's unique abilities and character traits into the Lord Windrunner's world. However, you may need to search through various fanfiction platforms to find one specifically like this.
Another theme is power and its corrupting influence. Sylvanas has held significant power, and fanfics often examine how that power has shaped her. Some stories show her struggling to resist the more corrupting aspects of power, while others show her succumbing to it and the consequences that follow.
Yes, she does. Sylvanas has a complex and original story within the World of Warcraft universe. She was once a high elf ranger - general, then endured great tragedy which led to her transformation into a banshee and her subsequent rise to power in different forms over time.
