The Harlock Family is a Germanic descended bloodline known for their military exploits and leaders, originating from Heiligenstadt. After World War II, it has kept a long and strong friendship with the Oyama family from Japan. One of the most notable is Captain Harlock, the pirate captain of the Arcadia.
The Harlock family in the earliest years describes the Harlock family in the middle ages with a captain in the army of the Knights Crusade. After getting recognition in World War II, the Harlock family earned an estate known as the Arcadia that was passed down for generations. However by the time space travel became available and the Illumidas began the invasion, the Harlock family lost most of their provisions and the name fell from grace due to betrayals from both old rivals and the people of Earth content with their relative comfort.
