Classes
Barbarian:
Avoid sailor and soldier background. I don't mind a short tempered farm boy, but you're a colonist, not a viking raider.
Either subclass can work within that limitation.
Bard: AKA Skalds
Skalds, at least in my world setting, are Valor college. This is the default for Norse bards.
Cleric:
Any Norse deity, but keep in mind that some won't be appropriate to a new colony.
Druid:
I'm going to say "no" to druids for this game. The Norse have pretty much moved past them, and this sort of magic is considered Finnish.
Fighter:
Both Battlemaster and Eldritch Knight are a bit over educated for colonial work, and, frankly, EK is a bit over educated for Norway. Champion is the default.
Monk:
Monks are Eastern and haven't been heard of by the Norse. Or most folks.
Paladin:
Oath of Ancients is he default, but the other oaths MIGHT be possible, depending on how things go. Assume you're Ancient trained to start, and we'll see what happens.
Ranger:
Both Hunter and Beastmaster are fine. The colony will need explorers and hunters in the lean months.
Rogue:
Truthfully, Rogue is a it of a hard sell for a colony. The only appropriate subclass in unavailable to start, although may become available by level 3. However, I'll allow a Thief as Default.
Sorcerer:
Human Sorcery is Wild Magic.
Wizard:
Wizardry is not unheard of, but it's rare. Sorcery is the magic of Norway, at least for those who manage to acquire magic somehow. Still I WILL allow this with the Sage Background only. Note: Wizards can train Fighters to become Eldritch Knights and Rogues to become Arcane Tricksters. Learning spells without other wizards or a library may be limited, however.
Warlock:
There actually ARE some Great Old One warlocks at the colony, but they acquired their abilities after arrival. For now Warlock is barred.
