Shadow-of-Sundered-Star (Earth-2042)

"The peaceful one is at war without and within."

- Didact

The Didact, born Shadow-of-Sundered-Star, was a male Force-sensitive Forerunner Promethean who held an extremely high status in the Forerunner society as Protector of the Ecumene, head of the Warrior-Servant rate and supreme commander of the entire Forerunner military. He wholeheartedly believed in the Mantle the Forerunners held to protect life as part of the Living Force, and fervently opposed the Halo Array as a sin beyond measure. He was also the lover and husband of the Librarian.
