Aside from being really difficult to type (and pronounce) his name, Krygnk is a typical Dwarf hailing from the Melonchi Mines.
Dwarves in Arvale mine the material mithryl/mythril/mithril (in Arvale, no one is sure how it’s spelled either, so they just use all three) and other precious gems. They’re one of the few civilizations in Arvale that doesn’t use the gold standard, and because of this, they’re unbelievably rich.
Krygnk wields a giant dwarven axe of course, or sometimes a pick/shovel; depending on what is closer and what he’s doing. Like most dwarves, he wears armor all the time. I explained why they do this in Episode One and it was really funny, but I already forgot what it was.
In any case, Krygnk is dragged into the party because Duncan needs permission to enter a certain part of the Melonchi caves and is only allowed to enter with a guide. As the story progresses, it involves something being borrowed from the Mines and therefore Krygnk has to watch over it. Or something like that. I might have made that last part up to distract you. Either way, you’ll find out when the game is released soon. 🙂
