Honestly, this book and many like it hit FAR HARDER than Pathfinder... The history and lore of the Scarred Lands is everpresent and litterally bleeding to affect the world currently. All events and great figures of the past are manipulating events and environments actively, constantly, even when they aren't the primary focus of a Scarred Lands campaign, these books show (through telling?) how to build a living, breathing world full of danger and wonder! This is an excellent starting place, as the reach of the sea is vast, it will affect all communities tied to it... there is no escape from the fact that history leaves its scars!
