The Blood Maiden Forest wasn't a small area, in fact... in the entire circle of wrath, it had quite the infamous reputation, a place where even Demon Counts were said to disappear without leaving a trace.
Before it was called the forest of Abandonment... the place where a Demon Marques of high prestige was said to have disappeared; at some point during the last hundred thousand years, people started to disappear in it... millions of years have thread and the forest has always been a house of the worst horrors, its name changes constantly.
But by far, the most terrifying name attached to it might have been, The Blood Maiden Forest.
The moment this unknown entity took over, whoever entered it... be it man or demon, would never come out.
