Remnants of the Aether
A poisonous haze that came out of nowhere and engulfed the entire world 10 years ago. Exposing oneself to the Aether even for a second can drive one mad and inhaling it has proven fatal. The biodome barrier around Ehn’gha is the only thing separating it from killing off the last of the humans. The Lith’gha have devised a plan which they believe will rid the world of the Aether once and for all.
To make matters worse, the Aether corrupts all that it touches, living or not, binding demonic data to all things which transform them into far more dangerous versions of their past selves. Due to their malicious nature, the people of Ehn’gha have aptly called these new creatures, “demons” for lack of a better term. Even if one were to survive the noxious fumes of The Aether, the demons were quick to end the lives of those who remained.
