In the year AD 310 a Roman mutiny in Britannia breaks out. The events leading up to this rebellion is unknown, however it ultimately fails. In order to escape execution around 3000 soldiers and unknown number of their families board ships and flee Britannia. Initially they sail along the coast around Ireland, but fears of possible pursuit by Roman authority lead them to decide to sail to the islands north of Britannia. However, the winds blow the ships off course and out of the sight of land. Mistakenly believing that they were blown to the east, they sail west for many weeks. Starvation and thirst is rampant. Many of the ships are lost in the sea, as most of the vessels were unable to take the high seas. Eventually however land is seen and in 316 the ships land on what they believe to be the island of Thule. The city of Reme is founded (named after Remus). Of those who left Britannia records show only 1130 men survived the voyage.
The new settlement is able to thrive and over time expands. Overtime intermarriage with the natives leads to many changes in the Thulean culture. However, perhaps one of the most interesting aspects of the Thulean culture is the change to the figure of Jesus Christ. Several dozen of the original settlers were Christian, however the majority held other beliefs and no bibles were brought with them. By the 500s the dominant Thulean religion is a polytheistic belief system centered around Jesus being the king of the Gods after he killed his father Jupiter.
The Thulean diet is centered at this time around fish and livestock with corn and beans making up a small part of the diet. The population as of the year AD 800 consisted of 13,439 as shown by a surviving census. It is not known precisely how accurate this census is because many of the fishing settlements on the west and northern coast of Thule were abandoned in winter with the fisherman returning to the cities in the south.
The government was an absolute monarchy.
One notable document that survives from this time period are from the writings of Cacistus the Explorer in The Expeditions . Who in 559 led the first major Thulean expedition outside of the region. Heading south along the coast he met many natives and bringing back corn, beans, turkeys, dragons (believed to be alligators who were certainly unable to survive long in the northern climate, among other things. However as a result of his trades with natives horses were introduced to the mainland natives which would lead to a drastic change in their lifestyle in the coming centuries.
