"Ultima Thule" literally means "farthest Thule," representing the most distant place imaginable. It's the ultimate "end of the line," even beyond the already mysterious Thule. It symbolizes the limits of exploration and knowledge, a point beyond which nothing is known. Unlike a specific location, it's more of a concept. It's like the final level in a video game, where the challenges are the greatest. Often used metaphorically to describe something unattainable or the ultimate achievement.
