A not so noble crew?

So we had our Lord-Captain and a faithful, if quirky, ship.  What was needed now was a crew...

At the time I had four players all of which I'd run Dark Heresy for at one time or another and all of which had a decent understanding of the setting. A good start.
So we put our heads together and came up with the following:
Darien Erronius - a "Rogue Trader" and the recently appointed heir of our Lord-Captain.  Up until recently Darien had lived on the planet of Archaos in the Calixis Sector (the regional setting for Dark Heresy) a young nobleman living the high life in the upper spire. Not overly furnished in the brain department he'd managed to bumble through the Higher Schola (university) mostly through his athletic pursuits and being a member, and champion of the Schola Fencing team.  An accomplished duelist he'd made his fair share of friends and enemies and in mysterious circumstances (the tale changes each time he tells it - in a similar vein to his father) he lost his arm and now sports a beautiful bionic replacement. He begins the campaign as the Majestic's First Officer.
Theata Xan'thai  - a Navigator from a nomadic house, Theata is driven by wanderlust to travel the Void.  When the young and impressionable Darien first joined the crew Theata immediately befirended him and took him under his wing, teaching him about ship board life and acting in many respects as his Major Domo.  Rapid paralells were drawn between Blackadder and Prince George in Blackadder III... On board ship Theata fulfils the role of Carto-artificer.

Vyn Tanda - An Arch-militant with a shady past, Vyn was the ship's dual chainsword weilding Chief Bo'sun.  She hailed from a Forge world but  the stuffy, ordered life under the rule of the Adeptus Mechanicus was not for her and she "fell off the rails" taking to the Void and having a number of ruin ins with the law.  She eventually ended up in the army, possibly a penal unit, where she was eventually recruited by the Lord-Captain and given charge of discipline aboard the Majestic - the old adage of "use a thief to catch a thief" applies...

Finally we had Dungoof an Ork Freebooter.  The Lord-Captain's passion for all things Xenos was well known amongst the crew but the most visible evidence of it was the Ork Twist Catcher, a Runtherd by the name of Dungoof or was considered cowardly by his clan and driven out, ending up in the Captain's service, cleansing teh bilge decks of vermin and mutants.
