I had an epiphany for my spin-off fantasy trilogy. Considering how much I humanized the characters and setting, I think it is a little late for me to start introducing demons, dark lords, and other evils. The reason for this is because I created a human world where most magic and mythic creatures are gone. To introduce demons and dark lords at this stage would be contradictory to the continuity of Gradaia’s history and lore. Therefore, instead of demons and dark lords, my spin-off trilogy will portray Gradaia enduring an invasion from a foreign army from another previously unknown continent. Up until now, the people of Gradaia thought they were the only survivors of the fall of Homantis, but they will learn that they are not alone and their empire is not the only land in the known world.
I am thinking of basing this new conflict on the Viking invasions of Anglo-Saxon England during the Dark Ages as well as the Norman invasion of 1066 AD. When J. R. R. Tolkein created the kingdom of Rohan, he based them on the Anglo-Saxons yet made one significant modification of his own. In addition, to basing Rohan’s people and culture on the Anglo-Saxons, he made them a powerful cavalry force. The reason this is significant is because the real-life Anglo-Saxons were mainly an infantry army, which was one of the factors that led to their defeat at the hands of William the Conqueror. So Tolkein wanted to depict what the Anglo-Saxons could have been like if they had their own cavalry.
The Vikings were much the same way when it came to how they fought. They were mainly infantry and had little to no cavalry. Just as Tolkein did with the Anglo-Saxons, I will be tinkering with what the Vikings could have been like if they had their own cavalry. However, this new culture will have a much more balanced military when it comes to cavalry, archers, and infantry than Rohan did. Also, I will be watching documentaries that talk more about Viking history, culture, and mythology. This will enrich my medieval knowledge even further.
