I think the reason the preview rulebook link on the front page is broken is that the preview rulebook is no longer necessary. ZRG has provided the updated rulebook links in update # 28 of the KS page.
JimmyS66 replied to hibbidyjibbidy's topic in Lords of the Eastern Reach: Speculation & DiscussionHey there, ZRG provided a link to the rulebook for the game in Update #28 of the Kickstarter. The rulebook is hosted on their website as well as Boardgamegeek. Once downloaded, all of the single player rules can be found on page 21 for your reading enjoyment
