This is exactly how I started out GM'ing this world. I started with the promised land (included in the ruleset / core rulebook) since it basically takes you into the country from the old country. You only need to know the basic back-story and the basic rules to run the starting adventure... everything else is pretty much explained. I've been GM'ing this ruleset now for... maybe 3 years? It's still amazing fun and the grim dark setting (and punishing monsters) puts the players on their toes every time they venture out into Davokar :)
