In the lands of Atlena, a world full of fantastic beasts and many different races, is currently a great war going on.
The different races and their gods split into many factions and groups and fight each other for many big and small reasons.
Armies march through the wild lands aggravating the beasts and creatures that dwell away from civilization.
One of theses many creatures is a dryad whose forest got decimated by the army of the Heavenly Empire which consists mostly out of humans.
They chopped down her trees to build an outpost, but once they finished building it, they started to set the rest of the forest on fire to clear out a bigger space around the base.
The dryad accepted them cutting down her trees to build their base because she understood that they need a roof over their heads, but the whatnot destruction they caused by setting the rest of the forest on fire snapped her last trace of patient.
In her rage the remaining forest starts to howl with murderous intent and strangely black and green plants burst out off the ground.
