Ye Old School Castle of The Mad Arch Mage

Downloaded a copy of Joseph Bloch's "Castle of The Mad Arch Mage." It's a huge dungeon, 13 levels and some 182 pages. Just a cursory review leaves me fairly impressed with a hardy, "thanks for the hard work." I've downloaded a copy of it and and have started reading it. It's done in the old school tradition, mostly a keyed map. Old school players know, the story comes by playing. The module is compatible with Labyrinth Lord, other simulacrum, and ol' Dungeons and Dragons. You can download The Castle of The Mad Arch Mage here.
