Citadel Charum

The Citadel Charum was a grand Precursor structure on Charum Hakkor. It was considered by the ancient humans to be the greatest Precursor ruin left on the planet at the end of the Human-Forerunner War.

History
As the final planetary defenses collapsed and their defeat became inevitable, the last surviving humans gathered in the Citadel on Charum Hakkor. One by one, the wounded, the dying, and the captured were laid out on rows upon hundreds of rows of beds inside the citadel. In an attempt to conceal their identities and ranks from the Forerunners, the Admiralty had stripped off their uniforms. Despite this, the Didact was able to identify his greatest opponent, Forthencho, the Lord of Admirals. Furious at humanity, the Old Council - mainly comprised of Builders - had originally ordered the complete annihilation of the human race despite being convinced that they knew of a cure against the Flood. The Librarian became convinced that humanity and their culture needed be spared, as this might be the only way for the Forerunners to decipher their apparent Flood immunity. The Council then tasked the Librarian and her Lifeworkers to extract the essences of the human survivors on Charum Hakkor, refusing to provide anything other than Composers as a means to accomplish this. Inside the citadel, the Librarian and her Lifeworkers walked among the human survivors providing relief before their imminent composition. Forthencho, Yprin Yprikushma, the Admiralty, and their children and families were then processed by the Composers, killing their physical selves but storing their memories and consciousnesses.
