Umbra Forest is a region in Sylestia situated north of Viridian Meadows, Astryl's Vale, and most other regions of Sylestia. It is accessible after clearing the Nightfall Bandit Camp in Viridian Meadows.
Umbra Forest is identifiable by its large, dark forest, cut through by a long river. Its main city is the Sanctuary of Saerielle. To the north, some of the trees seem to become snowed on, and to the south, the forest lightens and clears as it enters Astryl's Vale and Viridian Meadows.
Most enemies in the Umbra Forest region are between level 20 and level 45.
