Primordial

The Prisoner of Charum Hakkor was an individual of great power detained on Charum Hakkor. Unbeknownst to most of the galaxy, this individual was in fact the last living Precursor.

History
The creature was discovered by humans after they colonized Charum Hakkor, contained within a capsule of Precursor origin. Despite the advanced nature of Precursor technology, the humans managed to find a way to communicate with the captive for brief periods of time. They came to regard the creature within the cell as an oracle of sorts, asking it questions in the hopes of gaining greater understanding. Most of the time, the prisoner's answers were confused or unintelligible.

When the Flood first made an appearance in the Milky Way, several humans questioned the prisoner as to the nature and origin of the "disease". When the prisoner gave them an answer, the humans present were so deeply horrified that many of them committed suicide.
