Murphy did not run.
He had already figured out the current situation.
If measured by the common era, this was roughly around 400 CE.
Many things had happened on this land of Great Britain.
First, because the Huns, who had been beaten so badly by a mysterious ancient country in the distant east two hundred years ago that they could no longer survive, migrated west, Europe was nearly slaughtered all the way through by the Huns—even if they could not defeat that mysterious ancient country of the east, the Huns' combat strength was still enough to crush all the barbarian tribes in Europe.
Whether the Alans or the Goths, they collapsed at the first touch under the Huns' powerful offensive. To find a way to survive, these Germanic peoples had no choice but to migrate west, which ultimately led to the Holy Roman Empire being struck by the barbarians and destroyed.
Thus, the Romans, who had ruled Great Britain for nearly five hundred years, had no choice but to withdraw from this distant, remote province, granting the Britons freedom and the right of "self-defense."
As the rulers withdrew, Christianity, which had originally established an absolute advantage during the process of colonization, was challenged once again.
Along with the military forces rising across Britain, the native polytheistic beliefs that had once been suppressed by Christianity began to raise their heads again.
At the same time, the migrating Germanic peoples—the Jutes, the Anglo-Saxons, and others—as well as some Greeks and Romans who had been smashed by the Germanic peoples, fled to the British Isles, bringing their gods with them.
On this land now were the Christian God, the Celts' native Tuatha Dé Danann, the Norse Aesir brought by the Jutes, the Olympian Gods of the Greeks and Romans, and many other deities.
