If anyone is looking for low-level filler material for Age of Worms, I suggest using "Devil Box" from issue 109. It's a perfect fit for Diamond Lake: just replace "Quigley's Festal Freakshow" with "Zalamandra's Emporium." You'll probably need to scale it up a bit, since it was written for 2nd-level characters.

It's a short adventure, but it has lots of potential for good role-playing, which is missing from Three Faces of Evil.

I'm all about more filler material (I never run stuff in as aggressive and quick-levelling a manner as it's apparently intended). So let's see - waht good historical stuff, semi-recent Dungeon material, etc. can get incorporated?

Well, of course because of the location, there's a huge amount of classic Greyhawk material that can be used. If you don't have Greyhawk: The Adventure Begins, you should get it, as it details the entire Greyhawk-ruled area in which Diamond Lake lies. It has a convenient guide to adventure scenarios set in the region - WGR1 Greyhawk Ruins, which details Castle Greyhawk, as well as a host of others that were set in and around the area. Of course, there's also Maure Castle, originally in WG5 Mordenkainen's Fantastic Adventure and now more recently detailed in Dungeon. The Falconmaster trilogy is set in the Free City, and the Star Cairns trilogy, more recently, is set in the Domain.

There are also some Living Greyhawk scenarios that revolve around the cairns and their secrets; these are available for free download.

The old City of Greyhawk boxed set and, to an extent, the other Greyhawk boxed sets were rich in adventure seeds, especially in the Greyhawk area. Rary the Traitor hit a lot of nearby locales.

But what about stuff that can specifially be set in/around Diamond Lake? I'll crawl my Dungeons here soon... I do remember that some folks set the excellent Night Below boxed set adventure starting in Diamond Lake.

Oh, and there's "Ruins of the Mistmarsh" by Sean Williams, available online:

For those that don't know, Canonfire! (http://www.canonfire.com)has a wealth of Greyhawk info, including all the Oerth Journals, many of which were written long ago by people who are working on all this now (like Erik Mona).

And if you thought Diamond Lake was seedy, wait till you get to Rowanfen....

Other adventures that could be easily used as filler material, without having the PCs travel too far out of Diamond Lake:

"Cry Wolf" from issue 102. Tamris Quickthorn would be from the Bronzewood Lodge, giving the PCs a contact there. It's a short adventure, probably playable in one 4-5 hour session.

"Fiend's Embrace" from issue 121 is set in the Cold Marshes, but could be easily adapted to take place in the Mistmarsh. If you didn't want to run this in its entirety, the encounters from Chapter 1 could probably be worked into Encounter at Blackwall Keep (the AoW adventure in Dungeon 126).

Does anyone have the maps for the Ruins of the Mistmarsh adventure? Apparently they were posted on Sean Williams' website for awhile, but his website link is no longer working. If anyone has this I would REALLY appreciate a copy. Thanks!
