After the catastrophic failures as Unmoving Virtue and Pious Ascension, the Blood Covenant had learnt from its mistakes. While other colonies fell before the combined UNSC and Sangheili planet-hopping campaign, Expansive Judgement, the new Blood Covenant, was fortified by a massive fleet. Modelling themselves on the Second Fleet of Homogenous Clarity that protected High Charity, the Expansive Judgement Defence Fleet formed a virtually impenetrable barrier of ship patrols, preventing infiltration and presenting a formidible wall of firepower against any incoming enemy ships. Though UNSC and Sangheili warships possess a significant advantage over their Blood Covenant counterparts, the sheer numbers and scope of the defensive perimeter would overwhelm an attacking force.
