First, you need to be well - versed in the lore of the Elder Scrolls and the other universe you want to cross it with. For example, if it's with a game like Final Fantasy, know the races, magic systems, and cultures of both. Then, create an interesting premise for the crossover. Maybe a portal opens between the two worlds. Start with a strong character from the Elder Scrolls, like a Dragonborn, and put them in a situation where they have to interact with characters from the other world.
One great Elder Scrolls crossover fanfic is 'The Elder Scrolls and the World of Warcraft: Convergence'. It combines the rich lore of both universes in an exciting way. The characters from each world interact in unexpected ways, like a Nord warrior from Skyrim meeting an Orc from Warcraft. Another good one is 'Elder Scrolls meets Lord of the Rings'. It imagines what would happen if characters from Middle - earth entered the Elder Scrolls world and vice versa. The descriptions of the new landscapes created by this crossover are really vivid.
The characters would interact in very interesting ways. For instance, Tyrion Lannister might be fascinated by the Dwemer technology if some of it made its way into the crossover. He would probably try to understand it and use it to his advantage in the political games of Westeros.
One great Elder Scrolls crossover fanfiction is 'The Elder Scrolls and the World of Warcraft: A Convergence'. It combines the rich lore of both universes in an exciting adventure. The characters from each world interact in unique ways, like a Nord from Skyrim meeting an Orc from Warcraft. Another is 'Elder Scrolls Meets Lord of the Rings: The Fellowship's Journey'. It imagines what would happen if the heroes of Middle - earth entered the Elder Scrolls realm. They face challenges like the Daedric Princes while trying to find their way home. And 'Elder Scrolls - Assassin's Creed: Hidden Blades in Tamriel' which has the assassins from Assassin's Creed operating in the world of Tamriel, adding a new layer of stealth and intrigue to the Elder Scrolls setting.
One interesting Elder Scrolls 4 crossover fanfiction could be one that crosses over with the Lord of the Rings universe. It might have characters from Elder Scrolls 4 interacting with hobbits or elves in Middle - earth. Another could be a crossover with the Harry Potter world, where magic from both universes collide.
The plot could involve characters from Elder Scrolls finding themselves in the world of Game of Thrones. Maybe a Dragonborn could end up in Westeros and get involved in the power struggles there. They might use their Thu'um to shock the people of Westeros who have never seen such magic before.
One common theme is the clash of different cultures. RWBY has its own unique culture with huntsmen and huntresses, while Elder Scrolls has a complex tapestry of races and kingdoms. Another theme is the exploration of new powers. When the characters from one universe enter the other, they often have to figure out how to use or adapt to new magical abilities.
One common theme is power struggles. For example, when characters from different Elder Scrolls settings meet, they often have to deal with who has the most power or influence. Another theme is the exploration of different magics. Since the Elder Scrolls series has a rich magic system, in crossovers, it's interesting to see how different magics interact.
One common theme is the exploration of different races. Since Elder Scrolls Online has a variety of races like the Altmer, Dunmer, etc., fanfictions often focus on how these races interact when they cross paths in unexpected ways. For example, a story might show a Dunmer and an Altmer having to work together despite their historical enmity.
Power - up is also a frequent theme. The main characters usually gain new abilities or enhance their existing ones by combining the powers from both universes. For instance, a Naruto character might learn a new form of magic from The Elder Scrolls and use it to become even stronger in combat.
