Helmet of Fate

The Helmet of Fate is a magical artifact that houses inside it the Lord of Order known as Nabu and works as a symbiot of sorts, allowing a host body to be used by Nabu to become Doctor Fate

History
The exact story and origins about the Helmet of Fate are as of yet unknown. However, what is known is that the helmet holds within it the magical powers of Nabu, who is considered to be a Lord of Order. Having no body of his own, Nabu has made certain that the helmet is passed from person to person, allowing for him to continue his work of protecting the world from Chaos magic.

At some point, the helmet fell into the hands of Kent Nelson, who used its powers to become the hero Doctor Fate and eventually became a member of the Justice Society. After many years had passed however, Nelson's wife Inza had requested that Nelson retire as Doctor Fate. The helmet was then locked in the Tower of Fate for 65 years, where it waited for its master to return. Nelson, now a widower, was forced to take back the helmet when Klarion the Witch Boy and Abra Kadabra kidnapped him. Nelson managed to escape his captives, but was severely injured before he could put on the Helmet and become Doctor Fate.

Instead Wally West put on the helmet, allowing Nabu to control his body and turn him into the new Doctor Fate. Nabu almost took complete control of Wally's body through the helmet, but Nelson convinced him otherwise. Now the Helmet of Fate sits on Kid Flash's shelf in Mount Justice, awaiting its new owner.
