Titans

Titans were an ancient species of gigantic humanoid beings, among the earliest and oldest races on Earth alongside the ancestors of the Aulians. Despite nearly perishing by the era of Humans, Titans eventually gave birth to Giants and their different offshoots.

Myths and legends
According to legends, both the Titans and the ancient Aulians were the first species created by an enigmatic race known in modern times as Precursors. The Titans were originally created as labor force for the Precursors, but were eventually given the task of protecting the world and guarding nature and peace.

Relations between the Titans and the ancient Aulians - who were created as servants before given the task of archiving knowledge and science - were always strained due to rivalry among the two primal races. To the Precursors' dismay, they could not stop wars between their children.

In an attempt to lower the damage caused by the mutual hatred between the Titans and the Aulians, the Precursors would go on to create and develop several other species, including the Feras, the Dwarves and the Centaurs.
