gravelord castle

"in a monochrome world, no hope is left, even the rotten isnt safe here. here only power speaks" this is one of the sentences writen in one of the monoliths of this hopeless land. inside of a castle inside a deep cave, the necromancer and his army lies, he is one of the most feared persons in this world, there are many how tried to enter inside of the castle...but no one of them retruned. will you be able to claim his throne? or will you serve him for eternity?
