Well, technology might show up in the form of energy sources. In the Game of Thrones world, there could be some magical crystals or substances that power various things like lights in castles or powering large siege weapons. This would also lead to a new form of economy based on these energy sources. And in terms of entertainment, instead of just minstrels, there could be some sort of holographic - like projections for shows, which would be a new form of art and also a way to spread propaganda for the different houses.
One way is through communication. For example, instead of ravens, they could use some sort of magical - technological device that can send messages instantly. This would change the way alliances are formed and wars are planned. Another aspect could be in the area of weaponry. Maybe there could be some advanced crossbows or swords with built - in tech that gives an edge in battle. Also, in terms of transportation, rather than horses all the time, there could be some sort of steam - powered or magic - tech vehicles.
One example could be the development of flying machines. This would change the way battles are fought and how people travel across Westeros. Another could be the use of magic - infused technology, like a weapon that channels magic more effectively.
Perhaps a group of inventors from Essos arrives in Westeros with new technological wonders. They offer to sell their inventions to the highest bidder. This leads to a race among the houses to get their hands on these new technologies, which range from flying machines to devices that can control the weather. As they compete, old alliances are broken and new ones are formed, all while the threat of the White Walkers still looms in the north.
In fanfic, advancing technology can change the power dynamics. For example, if the Starks got advanced weaponry like guns, they could better defend against the Lannisters. It might also change the way warfare is conducted, making traditional knights on horseback less effective.
I think the Internet would be really interesting. It would completely change the way information spreads in Westeros. People could communicate across great distances instantly. Nobles could use it for political propaganda, and commoners could use it to organize against unfair rulers. It would also change the way knowledge is shared, like maesters could access a world of information instead of just what's in their libraries.
The Industrial Revolution's concepts of mass production and factories could be introduced in the slums of King's Landing. This would create a new social class of factory workers. Fanfiction could explore how these workers might rise up against the nobility, similar to real - world labor movements. The Tyrells, with their agricultural wealth, might see this as a threat to their power as the economy shifts from farming to manufacturing. They could either try to suppress it or find a way to adapt and profit from it.
Guns could be incorporated as a foreign weapon brought by invaders from across the sea. They would be a terrifying and unknown force to the people of Westeros at first.
Well, modern technology in a Game of Thrones fanfiction would completely disrupt the power dynamics. Consider the Internet. If Westeros had the Internet, knowledge would spread like wildfire. People would be able to learn about different cultures and ideologies quickly. This could lead to the rise of new political movements. In terms of warfare, drones could be used for surveillance or even as weapons. It would be a strange sight to see a Lannister army being monitored by a drone from afar. And imagine the shock on people's faces when they first see a tank roll into King's Landing.
There could be a really interesting fanfic where a Dragonborn enters the world of Game of Thrones during Joffrey's reign. Maybe the Dragonborn would initially be seen as a threat by Joffrey. But the Dragonborn's powers could change the power dynamics in King's Landing. For example, if the Dragonborn has the ability to control dragons, it would be a huge advantage over the Lannisters who rely mainly on their wealth and military might at that time.
One way to incorporate a Dragon MC in a Game of Thrones fanfic is to give it a unique backstory. Maybe it was hatched from an ancient egg that was long forgotten. It could have a special bond with a particular character, like a Targaryen who discovers it. This bond could drive the plot forward as they face the challenges in Westeros together.
Dark Souls has a deep lore regarding ancient and powerful artifacts. In a Game of Thrones fanfic, these could be translated into powerful weapons or items. For example, a sword that has the power to drain the life force of its enemies, similar to some weapons in Dark Souls. This would change the dynamics of battles and political intrigue in the Seven Kingdoms as characters would seek these powerful artifacts to gain an advantage.
