Even forgetting for a moment that Norway needs broader buffs the Stave Church does not meaningfully fit into the grand scheme of their civilization.

Some broad conceptual suggestions:
- Remove the Stave Church completely.
- Give Norway a pantheon specific trait such as choosing two pantheon bonuses or getting a free pantheon at the start of the game, etc.

Something like +food for internal trade routes with that city as the destination (ie fish being sent inland) and a large +gold/science bonus specifically for your maritime international trade routes originating from that city.
- Toss in un-pillagable maritime trade routes for a kicker if balance appropriate.
