GRAY MONDAY. 1 August 3132. On that day, eighty percent of the hyperpulse generators throughout the Inner Sphere fell silent and humanity’s communications link across the stars was severed. While many looked to the Republic of the Sphere for guidance through the darkness, others used the crisis to advance their own agendas and political ideologies. As a new era began, old hatreds and rivalries, long suppressed in the optimism of Stone’s Peace, threatened to overwhelm all that had been achieved in the new century. A Dark Age had fallen, one that would see the death of empires and the rise of tyrants. And the seeds of destruction would be planted in these first days after the Blackout. Era Digest: Dark Age is a mini-sourcebook that explores the pivotal developments in the immediate aftermath of the HPG Blackout, giving players a glimpse at early reactions to the crisis and the rise of the splinter factions fighting to take advantage of the chaos. Complete with rules and stats for several Dark Age units, Era Digest: Dark Age also features role-playing support for this crucial setting in BattleTech history! - from the publisher's blurb
