Return to Perinthos: A Memorial Book Fundraiser in the Memory of Jennell Jaquays has just launched. It contains over 80 “one-spread” dungeons that can be used together or standalone, unpublished Q&A with Jaquays, and a mini-setting by Luke Gearing.
Pre-publication contributions can be seen here. Some of the OSR systems included are OSE, S&W, Cairn, and Shadowdark. There are also OD&D and AD&D contributions as well.
I've donated the Halls of Viridian Mist, a dungeon level for 4 to 6 Swords & Wizardry Complete characters levels 3 to 5. This challenging adventure features many tricks Jaquays used in her dungeons like non-linear loops, multiple elevations, interactive factions, and secret doors hidden behind other secret doors.
You can learn more, support the fundraiser, and get the book here.
The Crossroads of Chaldén, an adventure resurrected from 1986, which I had the pleasure of editing (mildly) and laying out has been published in July:
Crossroads of Chalden takes place near the barbarian lands of snow and ice. The people are gruff and suspicious of outsiders, and to folk from other lands they seem introverted and superstitious. First written back in 1986, this Dragonsfoot publication is a ready-to-play module with an introduction to a new world for First Edition Dungeons & Dragons. Plenty of information to flesh out the world in which Chalden lies, or to place it within the World of Greyhawk. Included is also helpful hints for new DMs in how to run and adjudicate the module. An AD&D adventure for Characters Levels 2-3.
