The Hullack Forest was once a part of the huge forest of Cormanthor and marks the northeastern border of Cormyr and the Dales. It was the most primeval forest in all of Cormyr, with numerous dark valleys and hidden vales that went unseen for decades and was likely among the most dangerous regions of Cormyr. Legends stated that it was full of ghosts and monsters. Cormyrean wardens and crown scouts often steered adventurers here in hopes of taming this dense wood.
By 1372 DR the Hullack Forest, the King's Forest and Hermit's Wood were almost all that remained of the southern reaches of Cormanthor in Cormyr, having been pushed back significantly during the prosperous reign of Azoun IV.
