Dungeon Masters Screen - 1e AD&D

There is not much that needs to be said about this. Millions of gamers out there have had to stare at this or its progeny for way too many hours. Some have seen their respective fantasy worlds from both sides. I was lucky to be one of those. Many a mystery has been created or resolved behind the screen as it were. I hate to give away trade secrets but I think enough time has passed. Be it for the preservation of the storyline, or in some cases the player controlling the character was a jerk, not all the rolls were exactly as described from behind the screen.....sorry!
