As noted above, the glyph for Earth got changed from a circle with a cross atop it to a straight horizontal line, but neither of those is close to the ToEE symbol for Earth (a triangle). 89 of the module has a dot in the center, just like the glyph). Air is a circle in all three (notably the illustration on p. Only one of the symbols for the four elements have connections to the elemental symbols in the adventure module T1-4 Temple of Elemental Evil.The original glyph for “Earth” gets turned into the glyph for “supernatural watcher” with a slight modification. Sometimes the glyphs got transferred between one meaning and another.Some of them are close to their original meaning (the Tyr rune in the Folio edition means “honor”, for instance, which is in the same ballpark as its original meaning, and the Ansuz rune in the Folio for “god” which is its meaning in the Futhark as well). Some of those designs survived into the Guide, but quite a few were changed. Many of the original designs were based on runes of the Elder Futhark.I have no idea why most of these changes were made, but I do have a few observations: They were also included in a later book (I want to say the Adventure Begins, but I might be wrong) in pretty much the same format as the Guide. More than half of the designs in the Guide are either modified or completely changed from the original version in the Folio. While I knew that the symbols themselves had undergone a few changes between the iterations, I didn’t realize just how many had changed.

Both the original Folio and the Gol Box Guide to the World of Greyhawk include a section on “Portentous Runes and Glyphs” (or “Run and Glyphs as the Guide has it).
