One idea could be to have the characters from 'Throne of Glass' (TOG) and 'A Court of Thorns and Roses' (ACOTAR) meet in a magical realm created by a powerful ancient artifact. For example, Aelin from TOG could be on a quest to find a way to defeat a new, powerful enemy and accidentally stumbles into the world of ACOTAR. There, she meets Feyre and they initially have a bit of a clash due to their different upbringings and leadership styles, but then realize they can work together to solve a problem that threatens both of their worlds.
When writing an ACOTAR and TOG crossover fanfic, character development is key. You can't just throw the characters together without considering how they will grow and change in this new situation. For instance, if you pair up Chaol from TOG with Lucien from ACOTAR, think about how their different backgrounds and experiences will influence their relationship. Maybe Chaol's loyalty to his kingdom will be challenged by Lucien's more fluid view of loyalty among the fae. Also, don't be afraid to experiment with the magic systems. Try to find unique ways for the characters to use their combined powers. This will make your fanfic more engaging and original.
No, they're not exactly the same. Webtoons can come from various countries and have different styles and themes. Manhwa specifically refers to Korean comics.
Webtoons can be seen as comics. They tell stories visually, have characters and plots like traditional comics, but they might have different ways of scrolling or panel arrangements for online viewing.
Good fanfic writing for a TOG and ACOTAR crossover requires a deep understanding of the source materials. Research the lore, the politics, and the relationships in both series. For the plot, think of something that challenges the characters from both worlds. A good way is to introduce a new, powerful enemy that neither world has faced before. In terms of character development, let the characters grow and change as a result of their interactions. For example, if Rowan from TOG meets Azriel from ACOTAR, they could learn from each other's combat skills and ways of thinking. Also, pay attention to the pacing of your story. Don't rush the important moments and build up the tension gradually.
