Forthencho

Forthencho, the Lord of Admirals was a human senior naval officer who served during the Human-Forerunner war in 109,000 BCE. He commanded the forces protecting Charum Hakkor, including 10 stations and 40 "prime cruisers."

After the humans' defeat in the final battle of Charum Hakkor, he was captured along with many of the warriors under his command. In the subsequent interrogations, he denied the Forerunners the information that would lead them to successfully defeat the Flood again. Eventually, his physical self was executed, though his memories and neural patterns were harvested by the Librarian, who had use for them in her future plans. He attempted in vain to convince the human government to draw the Flood back into the galaxy as a weapon against the Forerunners. Ultimately, he was overruled by Yprin Yprikushma‎ and remained bitter about the decision seeing the flood could have been humanity's best hope of prolonging the war.

Forthencho was an ancestor of the chamanune Chakas and his memories were implanted in the young human's mind through a geas. This only became apparent after the relocation of The Timeless One and the destruction of the Charum Hakkor's Precursor artifacts. Despite his mistrust and hatred of the Forerunners in his decendant's time for "devolving them like animals", he noted to Chakas that he had felt a deep respect for a Warrior-Servant and his main rival during the war, The Didact. Despite this, he attempted through Chakas to use the Halo working with Mendicant Bias to destroy the Forerunners.

Trivia
Considering his title, its likely that he was the ancient human equivalent to the modern title of Chief of Naval Operations or the more senior Chairman of the Security Council used by the United Nations Space Command.
