Darksoul oozes 'professional'.  His dress is impeccable.  His dark hair is shaved to a length that speaks 'corp' rather than 'military', though his bearing suggests he's had more than a little experience in the latter.  His dark complexion is invariably clean and well-shaven and, when he speaks, he's soft-spoken with just a hint of an edge that suggests he expects to be listened to.

He appears equally comfortable in the suit of an upper-tier wage-slave, or in his well-broken-in leather biker's jacket.

It's not uncommon for his friends to be deep in conversation only to look up and find him leaning against a wall, listening - with no sign of when or how he appeared.
