In 3,000 BCE, the city of Atlantis, the fabled lost city of the gods, was a marvel of engineering and architecture. Its people, the Atlanteans, had mastered the art of time travel and were using it to their advantage in all aspects of life. They had time-traveling accountants, time-traveling chefs, and even time-traveling therapists.
But, as with all great power, came great responsibility. The Atlanteans used their time-traveling abilities to meddle with the timeline, causing chaos and destruction throughout history. They time-traveled to ancient Egypt, giving them an unfair advantage in the construction of the Great Pyramid. They time-traveled to the Wild West, causing the most epic of shootouts in a single afternoon.
