Obsessed with finding a way to raise an army of the dead, Lord Raavage sends Harnold the Deranged to the caves of Mitgardia to find the long lost Ring of Necromancy. Little did Ravvage know the Ring is protected by an ancient order of druids sworn to prevent the living from raising the dead!

The best part of this creation for me is that all the lighting in LEGO purist. You can see from the first photo (as well as the video in my photo stream should you dare... I wasn't sure video would be allowed, so it is NOT in the set) that the lava is being lit by light bricks turned on and off by a PF motor and LEGO shock absorbers/springs. The other lighting is done by LEGO PF LEDs and a red light brick.
I was first inspired to build something "castley" by DCs CCC MOC, ye old forge. This MOC uses his model's basic shape but modifies all the techniques to "Z"ify it.
