"Thule" refers to the northernmost region of the inhabited world in ancient Greek and Roman geography. Imagine it as the edge of the known world. It often represented a mysterious, remote place, shrouded in mist and legend. Unlike well-mapped areas, Thule was a realm of speculation. It's kind of like the unexplored areas in an RPG map. Sometimes, "Thule" is used metaphorically to describe anything distant or unattainable.
