Volf was always a straight-laced fellow, but recently he's moved over the line into (slightly paranoid) self-righteousness. Ever since his brother left to fight with the Stormcloaks, fear has been gnawing at his heels. He's taking it out on his crew, riding them harder than ever. He's doing it for their own good, of course: if the Dainty Sload is barred from entry at the ports, they'll be hard-pressed to pay the ship's expenses let alone the crew; if they run afoul of the wrong people, they could end up facing a lot worse than closed docks. The future of the Dainty Sload and every soul on it is balanced on the edge of a knife--so no wonder Volf is snappish towards his people. He's just trying to keep them all alive...even if it kills them. He has the standard sort of gruff Nordic voice, a bit stiff. He should sound like he believes he knows better than everybody else in all things.
