Rage

Under Skarbrand's influence, Guilliman's battle-brothers became more reckless and aggressive by the moment. Contaminated by the Daemon's fury, Amalrich and the last of the Black Templars turned aside from their route and hurled themselves into an onrushing mass of Khornate Daemons. Blood sprayed as a savage melee broke out. For a moment the Primarch considered diverting his own forces to help Amalrich's, but with Skarbrand storming closer and Daemons swarming on every front, there was no time. With a heavy heart, Guilliman barked orders through the vox, steadying the Ultramarines and their Primogenitors with the sheer force of his will.
