A Thunder Upon the land: Narva - Poltava

Experienced gamer, but new to this system.
Looking for someone to show me the ropes of the tactics in this game

To the extent it matters - I live in Calif

Where do you live in California? I’m located in San Jose.

I live in the mountains about an hour north of Grass Valley (N/E of Sacto or N/W of Reno - 2 hours either way)
(Korvessa = “in the wilderness”)
