The main feature of Necrovania is the large population of lycanthrope as well as the castle with the evil vampiric ruler Vampiras (Kaiju in proportions).
This ruler is a tyrant, and has ruled over this continent for many years...that is... until Zygosa destroyed him...now the continent is free (but still just as scary)
It is night most of the time, and the moons often passover it allowing for much lycanthropic discharge.
