Celestial

Celestials (or simply Endos as they are more commonly known) are self-aware constructs built by the Gods in the Dark Age.

Overview
The Celestials were the holy constructs or sentinels of the Gods, though the motive for their creation remains a mystery. During the End, the Celestial constructs built after the End had their memories shattered and nigh-all knowledge of their origins lost as well. During the final moments of the Dark Age several constructs landed on to transcend life and make a new construct known as Endos and made the planet a futuristic and technological world that dates several thousands of years ahead of normal humanity's technology.
