Ur-Didact

The Didact was the lover of the Librarian; these two beings were Forerunners and a conversation between the two can be found inside the Terminals in Halo 3. When the Terminals are accessed, the player is eventually moved to their old conversation that was recorded before the Halo rings were fired. He held some high status in the Forerunner Military, due to hints in the Terminals, and evidently wholeheartedly believes in the "Mantle" the Forerunners hold to protect life. He is also the one who activated the Halo Array.

He was constantly trying to convince the Librarian to give up on her mission to save other sentient life from the Halos, and return to him "Where it is safe". His pleas, however, were unsuccessful, and the Librarian ended up destroying her own fleet, stranding herself on Earth to live out the rest of her days in a place she referred to as "Eden". In the Iris campaign you can read Didact's final recorded words right before the Halo array Fires. However when reading the messages in the Terminals Didact states to the Librarian that he will continue on the Great Journey with out her. It is still unknown what Didact's fate was.

 

 

Trivia

• The word "Didact" actually means "one who teaches" in Latin. From this information, one could infer that at one point in his life he did some important teaching in Forerunner culture. The name Didact could come from the word didactic which means to instruct others in morals. This is rather ironic because he wound up being the one committing galactic suicide, firing the metaphorical gun at the head of the galaxy.
