Kuroinu Rebellion: The Dark Queen (Patreon)

 "Several Hundred years ago, a giant castle known
as the "Black Citadel" had appeared in the north. 
You could say that its appearance was the origin
of a great change, setting a chain of events that
would culminate in a war spanning entire
generations. Powerful Dark Magic had turned the land
surrounding the Black Citadel into a barren
wasteland in mere minutes. 
The Sky became blood red no matter what hour
of the day it was.
It was a land filled with noxious air devoid of
all vegetation. Any and all fresh wetlands had been
turned into murky toxic swamps.
Just being in the area was enough to weaken the
constitution of any mortal, to say nothing of how it
stripped away morale.
Inside however was rumored that a beautiful dark
elf sat at the top of the Black Citadel. Soon enough
this area became known as the
"Dark Queen's Country"."
