Devastation of Baal Part 1: Fall of the Shieldworlds

The Cryptus system had a second name: the Cryptus Shield. It was the Blood Angels' first line of defense, a network of worlds meant to prevent any meaningful invasion from reaching their homeworld of Baal. In the final years of M41, a splinter fleet of Hive Fleet Leviathan—known as the Cryptus Tendril—began curling around the Red Scar region, a stretch of space marked by a blood-red stain across Imperial star charts. The path it was taking led directly toward Baal.

The Shield Worlds Prepare

The Imperium responded by fortifying the Cryptus sector to the highest possible degree, despite the fact that no Space Marine chapters could lend aid—they were busy mustering their own defenses elsewhere. The system's population, combined with those in the surrounding Red Scar, numbered over 40 billion people. These were hardened survivors: the worlds were dangerously radioactive, and it was rare to find any citizen unarmed. Three million Cadian shock troop regiments were diverted under General Malandrost, alongside Vostroyan Firstborn regiments and tens of thousands of Battle Sisters led by Canoness Magda Grace of the Sacred Rose.

The Hive Mind is hungry, and it's heading straight for the Blood Angels. In part one of our massive Devastation of Baal coverage, we're joined by Kirioth to break down the Cryptus Campaign.

What was supposed to be the ultimate shield system against Hive Fleet Leviathan turns into an absolute nightmare of frozen bug ships, desperate Cadian last stands, and a Tyranid swarm so massive it literally blacks out the skies. Things get so incredibly bleak that Commander Dante and the Blood Angels have to rely on a literal C'tan-throwing Necron team-up just to buy some time. We cover the tragic fall of the Shieldworlds, the Sanguinor finally breaking its silence, and why Dante is just having the absolute worst week of his long, long life.

Part 2 coming next week!
