The Elsenwood is a great and ancient forest on the northern border of Viridistan. It is also home to the largest elven nation anywhere near Viridstan.
Viridians generally regard the elves of the Elsenwood as flighty and untrustworthy at best and outright thieves at worst. The elves in turn have been known to take strong objection to humans trying to cut trees in the Elsenwood. As a result, Viridstan built a fortified wall along the entire Viridstan-Elsenwood border many years ago. More recently, the Emperor has spent a great deal of money and manpower on enlarging and strengthening this wall.
