"[b]FOR THE EMPEROR![/b]" 

Despite being confined within his crate, Uriah's voice rang out and echoed across the hold they were in as if he had been upon a dias in the center of the room. As soon as the proclamation left his lips, his crate was shattered into so much kindling, and a shining example of what it meant to be Astartes materialized from the wreckage. His bolter out, he fired three rounds into the nearest guards. One chest was popped like a melon and two heads were turned into blood and bone paste. 

The crate would have been cramped for him even without him being clad within his shining power armor, but he took it without complaint or threat. He was truly honored to do his Emperor's work. He strode forward, having seen that in the scant seconds of his release, his brother marines had already taken care of almost everyone else in the room. It was to be expected. "Good job, brothers." he said, hefting his bolter and reloading while he had the chance too, simultaneously striding forward, his presence powerful and bright. 

Normally he and his fellow Ultramarines were not used to working with their other brethren, but the fact that they were all here and not apart of the traitor legions indicated that they would give their lives for the cause that he himself held so highly. For that, they were his brothers without doubt or fear. He took it upon himself to catch up with Ferreus at the fore, stoic and vigilantly gazing around at new threats that would dare present themselves.
