It's a shame the Hellraiser series has devolved into such a misbegotten crapfest. Much like Lovecraft's Mythos, Barker's mythology of Phillip LeMarchand and the servants of Leviathan has served as a rich source of inspiration for both professionals and amateurs. Sadly, the results vary just as wildly in quality.
"Steelghost" brings us one of the better examples built on Barker's foundations - the Zosimus Documents. I'm a sucker for faux documents to begin with, and this collection does a nice job of developing the history of the puzzle boxes.
