The idiosyncratic approach pointed out by
@Sparky McDibben and
@pukunui gives me the biggest headache with the idea of the campaign.
Do I keep it exactly as written and let it be Norse flavoured gaming without the secret Aesir/Vanir Ben and Jerry’s recipe.
Do I change the characters - Mirgul is clearly Loki. Boda is clearly Angahboda. The various gods clearly have direct equivalents - Freya etc.
Or Do I let the players chose names for their mortal characters from those of the Norse gods and let them be the epic figures over who legends will one day be told. I’m very tempted by this option.
