I find the chronology confusing with respect to the tollhouse and the inn that was set on fire by the goblins and gnolls, to kidnap Ravenheart.
Despite the 1 century devastation, these remained operational. The tollhouse has some diaries of diminishing travel on the road, but that happened much more recently than the Sharran attacks, and the corpse of the master of the tollhouse had been decaying for some time, but certainly much less than a century.
And the inn was still completely operational and intact when the delegation of the Duke arrived there.
So the 1 century of desolation does not quite fit with this.

But it's quite possible that I missed some important info.
