It will take perhaps three prologues until the actual story takes place.
Prologue, Part 1: The Rise of Medieval England
Germanic tribes of mainland Europe drove the Romans out of Europe - which didn't matter because the Romans were already crumbling. Anglos and Saxons formed the majority of the land, forming the 'Anglo-Saxon' territory. The Germanic tribes didn't agree, however, and disunity was ever present. The Kingdom of Wessex controlled London, the first major city in England. Wessex territory quickly took Kent, a minor kingdom. Sussex and Dumnonia fell, too. Wessex's king, Sigeberht, invaded the north, into Mercia and Northumbria. Wessex now bordered the grand Viking occupation of Scotland. However, war was not necessary because the Vikings withdrew from the city. France in the south disabled Wessex expansion in that direction, and Viking Scandinavia prevented expansion in the east. Thus, the large island in which the Celts settled was invaded. The Celts surrendered, and 'Dublin' was settled. With the British Isles and Ireland settled, the Wessex looked out to sea.
At around 1000 AD, the Kingdom of Wessex was completely united. Wessex formed into the new 'Kingdom of England' ruled former Wessex territory. Also, with so much territory, the English sent settlers through French and Spanish lands, hoping to find lands fit for settling. They came to North Africa, where the Byzantine Empire had ruled since the Roman Empire toppled. The English settlers exited the boats and settled the city of Tunis near the ancient city of Qart-Hadasht's ruins. Tunis established a border in Africa, which halted Byzantine expansion. The ships that took the settlers to Africa, the 'Royal Navy', were attacked by a Viking trireme. This started the Viking invasions, which stood in place for about two hundred years. However, for the next two centuries, no major invasions would take place.
The Royal Navy's high general, Major Edward Bent, built a new ship called a 'caravel' that was he first ship to sail into the open Atlantic Ocean. Bent led many, many men into the open ocean searching for gold. What Bent found was an intelligent civilization. The Aztec people had settled the land, and they were very proud. However, seeing a superior force, the Aztecs swore fealty to Bent and his men. Traveling southeast, Bent set sail for the southern continent. With new technologies, the English exited the Medieval era and entered the Renaissance Era.
