Story line :

The dark clouds shrouding the earth the day it began, and how the earthquakes followed. Then, without warning, spherical mounds of ash started forming on buildings and the ground, the spheres burst and ugly, horrific monsters had emerged. We began to call them the Gillianths. 

They spread and countries fell one by one, Armies threw everything at the creatures, but it had all been futile. Riots appeared more often than not and people no longer felt safe walking on the roads at night. Many of the rioters were angry, They'd lost friends and family in the chaos. 

And now a group of people seeking for justice called, The Dungeon Hunters to satiate the citizen's desire for vengeance against the Gillianths.
