The original Episode 56:
Episode 56: Dungeons of Castle Blackmoor Deeper Still
Conversion of the published Dave Arneson’s Blackmoor Adventure: Dungeons of Castle Blackmoor for higher level play. A call has gone out for only the bravest of adventurers who are foolhardy enough to enter the dungeon of Castle Blackmoor. A Dave Arneson’s Blackmoor adventure for PCs levels 7-13.
I've actually toyed with the idea of completing a supplement for the DoCB book that would allow MMRPG characters to play deeper levels in the spirit of Episode 56, since it never came out and we had the number reserved, but I never got around to it. If Jeff's sequel to The Redwood Scar ever comes on, I'll reconsider doing it again.
I was part of the Blackmoor MMRPG staff back in the day and these were what we had down on our "forthcoming list".
You're welcome.
