Legendary Void Hunter

Contemporary civilization has been destroyed by a supernatural disaster known as the "Hollows". They grow exponentially out of thin air, creating disordered dimensions where mysterious monsters dubbed the "Ethereal" roam. New Eridu, the last urban civilization that survived the apocalypse, managed to thrive by acquiring the technology to extract valuable resources from the Hollows.

As New Eridu became the city of miracles and attracted more resettled residents, it also started the massive exploration of the Hollows for its perpetual expansion. The Hollows then became industrialized and monetized under the city's administration, which gradually led to the increasing tension between monopolistic enterprises, gangs, conspirators, and fanatics.
