From the publishers blurb:
The Dragon's Secret
A Lost Temple,
a Mythic Hoard,
and a Legendary Lie!
A fantastic Tapestry of Mysteries that are waiting to be solved by a party of 6-8 5th to 7th level Adventurers.
The Dragon’s Secret centers on a mystery from the past: villagers invited a gold dragon to bless and protect the region with her presence… for a little tribute… and a temple… and followers... and perhaps just a whole lot more tribute. When the dragon eventually went mad, she laid waste to the surrounding lands in a fiery rage, ending with her death at the hands of heroes. Except… they found almost none of her treasure. In time people forgot the cathedral’s location, but the legend of her missing treasure still inspires seekers to keep looking.
This adventure, published in an abridged version in 2017 as part of a limited edition fundraiser featuring the work of TSR alumni, marks the return to tabletop game publishing of Hall of Fame designer and artist, Jennell Jaquays, the creator of enduring game settings such as the D&D adventures Dark Tower and Caverns of Thracia (Judges Guild), Griffin Mountain for Runequest (Chaosium), and M5 Talons of Night and FR5 The Savage Frontier for D&D (TSR, Inc.).
The self-contained adventure fits into any campaign setting and opens the first door to The Thousand Worlds, Jaquays' own game multiverse.
In addition to the adventure, the book includes “homebrew” rules variants for Swords & Wizardry, new monsters, and new playable character races for those not too shy to add a talking duck or an aardvark to their game world.
