Serendipity seems to strike a lot in the blogging world, with lots of people riffing off the same basic themes and making many similar posts. Over at Demons & Dragons, Jarl Frå Oslo posted an image I'd just seen yesterday as I was re-reading early issues of The Strategic Review. It's from an article by Gary Gygax in issue 6 called "The Meaning of Law and Chaos in Dungeons & Dragons and their Relationships to Good and Evil." It's a very fascinating article, because it's a glimpse into Gary's mind as he's expanding the threefold alignment structure of OD&D into the fivefold structure we see in Holmes.
Even more interesting, from a historical point of view if no other, is the aforementioned image, which doubles as an alignment graph and a map of the planes as Gary then conceived of them.
Notice the names: Heaven (not "Seven Heavens"), Paradise (not "Twin Paradises"), Elysium, Limbo, the Abyss, Hades, Hell (not "Nine Hells"), and Nirvana. There is also no plane associated with Neutrality, which is telling, I think. Notice too the beings listed as exemplars of the four cardinal alignments: Saint, Godling, Demon, and Devil. (What exactly a "godling" is I do not know, but I have some guesses)
I hope I'm not alone in thinking that this simplified structure, reminiscent of the more convoluted version we get in AD&D, is just keen. Like many aspects of OD&D + Supplements, I find that the end result is a kind of proto-AD&D or "AD&D Lite," and that's exactly the vibe I want in my games. In looking at this illustration, I was reminded of the planar structure Paizo adopted for its Golarion setting, which is eerily similar. Knowing Erik Mona's love for the old school, I'd not be the least bit surprised if this article was an inspiration when he and his crew were designing Golarion, but I have no proof of that. Even if it wasn't, I'm tickled to see some commonality between a 30 year-old article and contemporary game design. That doesn't happen everyday, alas.
