The Black Ruins

From the introduction: Blackened esoteric obelisks, henceforth known among most folk as ‘The Yore Standing Stones’, dot a strangely unnatural hill. The runes are inscribed with runic scripting, but it is what looms below the forlorn hill that should chill any good serf to the bone. Maintaining compatibility with any old school fantasy role-playing game or retro-clone, this is an adventure for 4-6 players arrayed around levels 1-3. This work can be made compatible with newer editions with minimal effort.
