Following the splitting of the Dark Angels fleet in the aftermath of Perditus, Seneschal Corswain continues to hunt down the Death Guard forces under the command of the infamous Typhon. Now, a tense standoff erupts in the heavens over the supposedly independent world of Terra Nullius, and Corswain must either bend the local population to his own cause or make an example of them to other worlds that might secede from the Imperium. In this war, there can be no innocent bystanders.
