Barbarian-style crawler class or race, exemplified by the level 65 Donar-worshiping crawler Jurgen.
Carl identifies the crawler Jurgen as a level 65 Harii, which he describes as some sort of barbarian class. Jurgen fits the archetype physically: a large human with a shock of blonde hair and arms that look as if they could bend steel.
Carl notes in the same breath that Jurgen worships a god named Donar, suggesting the Harii carry a Germanic warrior-cult flavor of the sort the dungeon likes to hand out. It is a rare class for Carl to have seen this deep, and he records it only in passing as they keep recruiting their way down the rings of Larracos.
Represented by heavily muscled warrior types built for close combat.
