Worldbuilding notes:

The Kingdom of Montemshaven sits about a day's travel south of the Montem River, which separates the colder, harsher northern climate and mountains to the milder south.

The large northlander village town of Norvegrheim, or Norvegr, sits about 6 days' travel uphill from the Montem river, about 7-8 days travel North- Northeast of the Kingdom of Montemshaven

The Great Inland Sea is to the West by roughly 5 days' travel.

The border of Montemshaven sits on the Montem river; northlanders have always beaten back any attempts to annex any land beyond the river. Several villages sit sporadically within 7 days of travel.

The Kingdom of Montemshaven is a relatively young kingdom, with only two neighbors to the south-east and south-west. Being the most northern kingdom in the patchwork quilt of the 'civilized world,' they're generally remote and left alone by most going-ons. Having only been establish 4 generations beforehand, they don't yet have strong blood ties outside the three northern kingdoms, nor anything of note beyond some specific resources.

The native reindeer and caribou are much larger than normal. Northlanders generally tame and ride the caribou, and the reindeer are ridden more often than horses by the people of Montemshaven. Regular horses aren't used to the snowfalls, steeper terrain, or colder climate, so the few horses that are found are sturdier, stronger, and fiercer. 

The migration cycle of the caribou pass very close to Montemshaven- those caribou that aren't domesticated or penned as cattle are generally hunted as the herds pass. 

Furthermore, because of the large size of the local four-leggeds, regular wolves are somewhat uncommon. One's more likely to run into the smaller packs of the much larger direwolves, and even more rarely than that, the extremely dangerous sabertooth- the belek. The belek has been often considered to be one of the most dangerous creatures in the world, easily more dangerous to the southern orcs, or the mountainous goblins. Beleks hunt for sport as much for food; they never back down from a fight, and will toy with their prey.

Culturally, the people are similar to Persian culture, with festivals celebrating the beginning of spring, midsummer, midwinter, and the passing of the caribou herds- which often number from several hundred to several thousand.
