- Daniel "delta" Collins has performed some new analysis of the first level map and key of Gary Gygax's Castle Greyhawk @ https://deltasdnd.blogspot.com/2020/01/subterrane-surveys-gygaxs-castle.html, with some interesting results---well-worth the read!
- Some excellent discussion about adventure module book design and usability in the comments of Bryce Lynch's recent review of the The Anthropophagi of Xambaala for Astonishing Swordsmen & Sorcerers of Hyperborea, one of my favorite creations from the OSR
- Illusions are in the air! Anthony Huso has continued his examination of house rules and interpretations to make sense of of illusions at his AD&D table, while over on Dragonsfoot a timely discussion arose in response to how mixed saving throws are adjudicated for a group of PCs facing down illusions
- Trent Foster has outlined the scope of the ongoing revisions to his AD&D Companion, now entitled The Heroic Legendarium!---an exciting new expansion to the core of AD&D's rules that I'm planning to introduce into my new Greyhawk Campaign :D
Your regularly-scheduled Mega-Dungeon Mondays will reappear next week =)
