At least that's the line on the cover of Dungeon 144
I just want to point out the adventure 'Diplomacy' in the current issue of the magazine because it's stuffed with planar material. Janni, a tertian modron, an arcanaloth archmage, xorn, guardinals, mercane... all sorts of good stuff. Chris Wissel did a nice job on it, and I had the opportunity to pitch in on some of the editing as far as the planar references were concerned.
I didn't write it, but I'm curious to see what folks' reactions are to the adventure. It looks like a good fraction of my suggestions got taken into account in the final version that went to print, especially as the 'loths are concerned.
Lots of fiendish goodness, so to speak: A 3.5 arcanaloth revision, a 3e reference to the Tower of Incarnate Pain, a reference to Helekanalaith, and a bit of detail on the fate of the Staff of the Lower Planes.
One thing of note here, as I get to read over my copy of the issue.
The modron was originally written up as an inevitable, and the switch to a modron seems to have been a last minute change. Some of the original fluff regarding the inevitable seems to have stayed in, so the modron is listed as a construct, and diamonds are mentioned as being a componant of modron creation and upkeep, when that line was originally meant to refer to inevitables.
