The Eastern Sign Post is the only landmark that doesn't grant any kind of bonus when you Enter it. It's not completely useless, though, as it still counts as visiting a different landmark for the purposes of resetting the bonuses from another, more useful landmark. What you do get instead of a bonus is an apparently useless hint ("Go east go east!"). This landmark can be found on a small island north of the Lands of Danger and Despair.
