This map appeared today on the new Dave Arneson Facebook Page. The map was recently discovered by Dave's daughter. It appears to be a photocopy of of the map from the First Fantasy Campaign book (JG). However, a quick comparison reveals never before seen hand written notes identifying the purpose of several of the rooms.

Given where this map was discovered, it seems likely that these notes are from Arneson himself.

It would also be interesting to compare this map in greater detail to the floor plans of Castle Branzol which formed the inspiration for the original castle. In 2006 ZGG published , but the book contained little information on the Castle itself. It has been speculated that both the Castle and the Dungeon could have been part of the never published DA5, of which there still may be a yet unrevealed manuscript out there.

In any case, this new map adds another piece to the puzzle that is Castle Blackmoor!

Is this the only new document released? I think I saw an isometrical map of the castle, one of these weeks, too, but it might not be from the same source...

Those maps are of the interior of Blackmoor castle itself.
