Sturvin is one of the "Sturmhalten sewer rats" assigned to guide Lars, Zeetha, and Da Boyz through the undercity. He's the tall, slightly cadaverous-looking one with a receding hairline and odd headgear. He and his associate Kalikoff have been working there for at least twenty-seven years, and know it well, apparently including the Deepdown (though they [ prefer] [[Chronology - Volume #|✣ ]] not to go there lately -- apparently it's become more dangerous since 20 to 25 years ago, when it was fun). They've become so used to the Sturmhalten sewers as "normal" that they can't quite grasp an underground ecosystem that doesn't include ghouls, albino squid, giant glowing rats, and so on.
