Chapter Summaries

Lin En assembled the Solar Fleet and Blood Angels commanders and set a three-layer defense against Abaddon's approaching fleet, aiming to hold the Solar System's eastern approaches until Calgar arrived. The fleets moved into position, with Admiral Aurelian's ships guarding the Oort Cloud and twelve Tyranid Hive Ships patrolling the outer perimeter.

• Lin En reviewed the Solar Fleet's ship and weapon data while waiting for the commanders to assemble.
• Lin En divided the eastern defenses into an inner blocking line led by Admiral Aurelian and an outer mobile force led by himself and Dante.
• Dante pledged that the Blood Angels would spare no effort, and Lin En ordered the Purple Carapace Chapter to the front and the Hive Ships to patrol the perimeter.

• Dante led the Blood Angels toward the hangar after declaring that the losing side would have to rename itself the Sons of Horus.

After Lin En ordered the crew to rescue the people from an Escort Frigate destroyed by a torpedo, they discovered that every mortal and Space Marine had survived the explosion and the vacuum of space.

Lin En crippled the Chaos Fleet’s daemon assault with the No-Fly domain and Psychic Storm, letting the Imperial Navy and its allies devastate the vanguard. Watching the defeat, Abaddon feared that Lin En might be an avatar of the Emperor because he knew private memories of Horus.
