A magnificent and tragic story of the Dark Angels' resistance to the Orc invasion. Faced with these xenos, the Third Company did not at first think much of the threat. And although the enemy’s numbers continue to grow, the capital Belial believes that its warriors are capable of cleansing the planet on their own. But the greenskins manage to take the Space Marines by surprise and somewhat perplexed with their technological achievements. If the Dark Angels do not hold out until reinforcements arrive, the Imperium could lose an entire system.
