If it weren't called Dungeons & Dragons, it'd be Magic & Mages. You can tell that spellcasters are the stars of the show in D&D. "Well of course," you might say. "The company isn't called Warriors of the Coast, or even Rogues of the Coast, though that last one has a nice ring to it." They're Wizards of the Coast.
There's somewhere around 110 pages of spells in the D&D 2024 Player's Handbook. Spells take up almost one-third of the entire book. You'd be surprised how many are named after Greyhawk characters. Greyhawk being the original D&D world created, bit by bit, in ever-widening circles, by D&D cofounder Gary Gygax.
I know Bigby from his 5e cover of Glory of the Giants. And Mordenkainen from the cover of the discontinued Tome of Foes, but also on the cover of Monsters of the Multiverse that replaced it.
There are several Greyhawk mages in the Player's Handbook Spells chapter besides Bigby and the prolific Mordenkainen. Many of the others, however, I'm only seeing for the first time, and they aren't all Greyhawk. Tasha, for instance, is from Forgotten Realms.
In total, there is: Bigby, Drawmij (no art, though), Evard, Jallarzi, Leomund, Melf, Mordenkainen, Nystul (no art), Otiluk, Otto, Rary, Tasha, Tenser, and Yolande.
Here's artwork that now puts a face to many of these named wizard spells:
Unfortunately there's no artwork of Drawmij or his Instant Summons.
No picture of Nystul either, though that's presumably because they didn't need a pic of yet another old, white-haired man in a pointy hat.
No image of Rary, but he was a traitor to the Circle of Eight in Greyhawk.
All of this spankin' new artwork of old school Greyhawk wizards is yet another excellent tribute to D&D's 50th anniversary, and leans heavy into the upcoming Dungeon Master's Guide that will use elements of the Greyhawk setting to walk DMs new and old through the process of running a world and everyone in it.
