Herold gave a stiff not to the Celestian as she set them right with how they'd proceed. He kept his mouth shut and eyes ahead as he waited for the time to move, and when it was due, he marched with a purpose. Making their way out of the meeting room and through the halls of blood that looked like what he'd assume was a chaos worshipers dream. He snorted at the comment about the Psyker, and then continued forward with the rest with naught but a word. 

The Vehicle bay was filled with Imperial armor, though to his surprise they didn't go with the Leman Russ Tanks, or even the Chimeras. He guessed it made sense, to be tactically less obvious. But with Orks, more protection never hurt. If only they had the grav vehicles. Herold had never ridden in one but he had heard rumors it was near silent in its advance. Dark Age tech was mysterious and hard to come by, however. He wasn't surprised none were here. 

Stepping into the vehicle, he found himself a seat as the Kreiger trooper began his banter. "Orks'll appreciate us just fine, then." He said grimly, thinking of how this was probably going to get messy, despite the plans made.
