Before William could reply, they were told to go to the dining hall. "Looks like we must meet in the dining hall" and he walked out of the armory. William walked into the room still fully in his armor, although he had taken his helmet off, and made his way to one of the seats. He looked around and noticed the large amount of space put into this dining room, this was easily one of the largest rooms on the ship. Another observation he made was of the decorations surrounding the large dining room. These decorations depicted the heroes of the Imperium and should be honored accordingly, William was happy to know that these men of honor were not simply dismissed. When the captain started talking he shifted his body position and paid attention to what he had to say. After him, Brother Carus introduced himself, along with Moyses. 

William stood up to introduce himself next, "Greetings, my name is William Selark of the Ultramarines. I have spent little time in the Deathwatch but I can no doubt be useful to the team. You may have noticed that I am a techmarine, and I will fulfill such duties. Long Live the Imperium." He bowed slightly and sat down, he wondered who would introduce themselves next.
