Doctor N.L. Babak was a xenobiologist and prominent member of the shadowy cabal known as Deep Void. In 2184, Babak accompanied a United States Colonial Marine Corps expedition to the Norcomm Ouragan Testing Facility on the Union of Progressive Peoples world of KOI-571.02 during a Biodrone Xenomorph outbreak on the planet. Babak was also responsible for the formulation of Absolute Zero, a freezing spray capable of arresting pathogenic development in an infected human and thus preventing their transformation into an Anathema.
