The corridors were narrow, and his foes numerous. The trance of battle deluded his mind, the timeless rhythm of combat defying the timer in his peripheral vision that insisted it had been a mere minute since the first shot had been fired. He was hunched, his bolter tucked tightly to his body, his feet moving in a graceful roll-step that landed silently as he twisted around a corner. Without hestitation, he snap fired two bolts, even as his visor highlighted the two forms as targets.
He pushed past the intersection, the sound of footsteps echoing in his helmet. In a single, smooth motion, he took his bolter by the foregrip, uncasing his combat knife, and thrust it around the corner, just below chest height. He felt a tearing as he flicked his wrist, ripping the unseen target open. Sheathing his blade, he reversed his bolter's grip, letting him pivot around the corner gun-first. One hostile exploded into a fine mist. The other, he grazed at the shoulder, sending it wobbling, but not quite off its feet.
As the buzzer sounded in his helmet, his hand flickered at his thigh, the combat knife flipping out of its sheath, turning once in the air and sinking to the hilt into the padded ballistic cloth target. Around him, the faux corridor walls sank back into the floor, revealing the vast expanse of the training gymnasium. He approached the target, sliding his knife free, absently shaking off fibers before returning it to its sheath.
The echoes of boltguns and the occasional scream of chainsword penetrated his perception as he switched off the simulated sound, and reemerged from his imagined battle to the real one. He approached the vestibule near his designated training field, reaching down to his belt and starting to sleeve empty magazines into a waiting case. A nearby serf watched in confusion and horror, as the Adeptus Astartes wasted his valuable training time sorting ammunition, but knew not to question the Marine.
Petrix knew that loading, sorting, and distributing ammunition swiftly could be just as important as being able to land it on-target. They did not always have the luxury of a full staff of Chapter serfs in the field, after all. More importantly, he was eager to begin squad exercises - and those did not begin with bolters drawn.
He exited the gymnasium and approached the armory, skulking through the mostly empty corridors. He moved silently, endeavoring not to be seen, even by his new brothers-in-arms. (Dedication to wraith-slip training was just another Raven Guard idiosyncracy that alternately irritated and unnerved the sons of other Chapters.) Bearing the case in one hand, he silently slipped into the armory, scanning the room, and finding the green-edged armor in a service vestibule. Moving with a purpose, he put his hand on Ar'Mat's shoulder - among Ravens, a friendly reminder to remain vigilant, and a silent greeting; though he did not know how the other Marine might interpret it...
