Durmista Forest

This forest is the remnants of the forest the used to span the whole north-west reaches of Umbara's Peaks.

It is protected by a fey presence which lulls intruders to near-sleep, such that they wander it trapped, endlessly daydreaming.

It's inhabited by Dryads, Wood Elves, and the last of the Eladrin - the elvish guardians of the forest.
