Despite the widespread destruction, Irius Prime remained untouched. Its remote location and lack of significant military installations made it a low-priority target for the Covenant. Although not directly attacked, the colony's leadership took no chances. They bolstered planetary defenses, established emergency evacuation protocols, and constructed underground shelters to protect the civilian population. As the war intensified, Irius Prime's contact with other human worlds became sporadic. The colony became increasingly self-reliant, focusing on agriculture and resource management to sustain its population. Despite the relative calm, the fear of potential Covenant discovery loomed large. The colony lived under constant threat, with frequent drills and readiness checks to ensure preparedness for any eventual attack.
