I have been taking my own kids through this well trod adventure for our current 1st Ed AD&D game.
For this time around I am adding some new ideas. Stealing from the Return to The Keep on the Borderlands and even some ideas that came up in my "Ash vs. The Keep on the Borderlands" for the Army of Darkness game. I am going to set up some of clues for the ultimate adventure they will be on (AGDQ+).
