From the blurb:
Born of the stars, nurtured on pagan blood, Castle Ragemoor exerts its will over any hapless mortal who dares set foot within its living walls! Fortress … sentinel … guardian … prison! Those who oppose it, it kills! Those it would enslave, it drives insane!
Seriously, a comic about a living castle drawn by the great Richard Corben that is equal parts Gormenghast and Lovecraft? Get out of my head! Do I really need to write anything further? I want to write up a mega-dungeon inspired by this and run it right now.
Note that Corben’s art is wonderfully adult-oriented (that is, potentially NSFW).
I read the hardcover compilation of the first four issues, which I believe encompasses the entire story (I don’t think more issues are coming). It is a quick read, and I’m sure I will return to it many times.
