Shadow of the Serpent
Watch Captain Marcus
Watch Captain Marcus has been in command of this sub-sector of Jericho Reach for nearly 20 years, the Black Templar (his home Chapter) found his permanent position in the Deathwatch a great honour. He has seen invaders of all kinds, from within and without. And has connections with many dozens of Inquisitors; many of which he does not trust.
He has a good report with the Chapters he calls his Kill-Teams from. At times he many be in command of more than one kill-team. With how well his Kill-teams have performed, Marcus rarely feels the need to lead the Deathwatch personally. However, this campaign may see him draw his sword once more.
