Headbutts iron

Enraged, the Blood Gorgon hammered the floor tiles with his fists. The tireless banging split the ceramic and brought down scuds of dust from the rafters. Still howling, Barsabbas rose to his feet and began to beat his own naked face against the generator’s iron bearing covers. The ridged metal scored his cheeks and opened up raw, bleeding lines across his forehead. Sargaul began to bawl too, stimulated by the loud noise. His eyes were fixed upon the ceiling and his clumsy tongue worked in a muted, stifled yell.

Barsabbas raged long into the night. He did not stop. Seized by an anguish that had no release, he began to tear down the processing facility with his bare hands. Bones splintered wood, boots dented metal. He raged until his fists were black and bleeding and the ceramite of his gauntlets was textured with scratches. Dust clouds fumed as he broke through the walls. Sindul sheltered behind a storage locker as the world crashed and shook. The Traitor Marine was like an earthquake or a storm. Sindul had little hope of escaping and was helpless to stop it.
