The battle for territory is common to both. In Game of Thrones, the Seven Kingdoms are constantly at war over land. Similarly, in Warcraft 3, races are fighting to control regions of Azeroth. For example, the Humans try to defend their kingdoms from the encroachment of the Orcs. Also, both stories have elements of betrayal. In Game of Thrones, there are numerous instances of characters turning on each other, like the Red Wedding. In Warcraft 3, Arthas betrays his own people and becomes the Lich King.
One great 'Game of Thrones and Warcraft Fanfic' is 'The Westeros - Azeroth Connection'. It combines the political intrigue of Game of Thrones with the fantastical races of Warcraft. Another interesting one could be 'A Song of Elves and Men in Azeroth' which plays with the character types from both universes.
Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. Some fanfics combine the complex political intrigue of Game of Thrones with the rich fantasy world of Warcraft, creating unique and engaging stories.
One popular trope is the 'fish out of water' story. For example, a character from Game of Thrones suddenly appears in the Warcraft world and has to adapt to its strange new rules, magic, and races. Another is the 'power - up' trope. A relatively weak character from either universe gains extraordinary power in the other universe's context. For instance, a peasant from Game of Thrones might discover they have a natural affinity for Warcraft's shamanistic magic and become a powerful force.
Power struggles are quite popular. Just like in both the original Warcraft and Game of Thrones, the fight for dominance is a central theme. In fanfiction, it could be about a character from Warcraft trying to gain power in the Game of Thrones setting, or vice versa.
In Game of Thrones, character development is often driven by the political and social environment. For example, Sansa Stark starts as a naive girl and becomes a shrewd player in the game of thrones due to the hardships she faces. In Warcraft 3, Arthas' development is more about moral decay. He goes from a valiant paladin to a malevolent Lich King because of his choices and the influence of the cursed blade Frostmourne.
One popular theme is the crossover of characters. For example, imagining how a character from Game of Thrones would fare in the World of Warcraft universe or vice versa. Another theme is exploring uncharted storylines. In Game of Thrones fanfiction, it could be about what might have happened if a certain character didn't die. In World of Warcraft fanfiction, it might be about new adventures in unexplored regions. And power struggles are also common. Just like in the original works, fanfiction often delves into who will gain power and how they will use it in these fictional universes.
The story of Warcraft 1 is set in a fictional medieval - like world filled with magic and war. It involves two main factions, the Humans and the Orcs. The Orcs, driven from their own world, invaded the human lands in search of a new place to settle. This led to a series of battles and skirmishes between the two races.
The intersection often lies in the exploration of themes. Both universes have complex political landscapes. In fanfiction, authors could create scenarios where the political intrigue of Game of Thrones, such as the backstabbing and alliance - making in King's Landing, is transplanted into the city - states of Warcraft. Also, the concept of honor and loyalty is present in both. A character from Warcraft might be faced with a moral dilemma similar to those in Game of Thrones. For instance, a night elf might have to choose between loyalty to their race and a newfound friendship with a character from the Game of Thrones world, much like Jaime Lannister had to choose between his family and his sense of honor at times.
