Although, ever since their victory, the Chosen One seemingly vanished, and was never heard of again, which led several beings, mostly lesser gods, to search for them in hopes of absorbing or abusing their power. After a long quest, after having made several allies, and having slayed several other Dark Gods on their path, the unnamed Champion managed to slay the Moon Lord, and later Cthulhu, freeing the universe from the Dark Lord's rule. This Chosen One took the form of a young human, the primary inhabitants of the world.

However, through the will of the five Elementals, a Chosen One would eventually be selected to slay the disturbance. The planet served as the battleground where Cthulhu and Noxus fought, and eventually slayed its creator, Xeroc, initiating Cthulhu's reign, during which, creatures of Darkness, or, more specifically, the many Children of Cthulhu, ran rampant as the world plunged into chaos under the reign of the now titled Moon Lord. Although peaceful at first, Terraria soon began to see its fair share of warfare.

The Great God of Light oversaw its creation, creating various creatures to inhabit such a world, namely, the Elementals, the Slimes, and various humanoids, who would soon to be followed by many more races. Terraria, although not the biggest, richest, or most diverse planet within its universe, or even galaxy, seems to be the center of attention for various gods, including Xeroc, the supposed creator of the universe and all that dwells within.
