Creed arrived with expeditionary troops and reunited with Benedict, who told him about Captain Aurora and the missing Viper's Fang. After the Primarchs discovered the tank concealed beneath Blackstone Tower Seven, Rogal Dorn decided to ignore Alpharius and focus on the greater situation.

• A teleportation device brought Creed, 100 Lamenters, and 1,500 expeditionary soldiers to the battlefield, where the troops quickly assembled defenses and began salvaging wreckage.
