And here is some info on Doctor Fate
Kent Nelson was the son of archaeologist Sven Nelson, and the two of them were exploring the Valley of Ur in Mesopotamia when they discovered an underground pyramid. It contained Nabu, an ancient immortal from the planet Cilia who had been held in suspended animation for thousands of years. Kent released him, but the lever accidentally unleashed a poisonous gas that killed his father. It would later be revealed that Nabu engineered this situation to gain a new host.

Nabu decided to mentor the young boy in the secrets of the universe, giving him incredible powers through total molecular control and taking his grief away from him. He would serve as an agent of the Lords of Order in their never-ending battle against the Lords of Chaos. Having finished his training, Nabu gave him an amulet, cloak and helmet to become a champion of good as Doctor Fate. Kent would go on adventures as Fate, although Nabu's spirit would always guide him through the helmet and he'd awaken with little memory of his own exploits.
