The Misanthropist

"The Misanthropist" was a fragment of abstracted personality. "The Misanthropist" was formed directly by the Gravemind in order to keep a hold on Mendicant Bias, even if the Flood's only true hold on the AI construct was a maniacal hatred for all things pertaining to the Forerunner as a race. This core wasn't destroyed upon its ferrying starship's destruction, but it had survived an orbital drop onto the Nikaru homeworld, where it would remain for millennia, influencing the Nikaru with it's hateful ideas about the Forerunner; ideology that would stem into hatred for the Forerunner's "Reclaimers", as well as any current Keepers of the Mantle, later on in history.

History
In order to prevent Mendicant Bias from subverting or harming him, Offensive Bias had shattered of Mendicant Bias into its component sections and scattered them throughout the few remaining ships of his fleet for transport to Installation 00, where he would study the fallen AI construct. Much of his fleet was destroyed or ravaged by the Flood. "The Misanthropist" being a rare surviving piece. This personality core crash landed on the Nikaru homeworld, where it would remain for millenia, influencing the Nikaru with it's hateful ideas about the Forerunner. Ideology that would stem into hatred for the Forerunner's "Reclaimers", as well as any current Keepers of the Mantle, later on in history.
