I am reviewing the print and pdf versions.
The premise is a fairly simple one. There is a ruined ziggurat in the Barren Woods that is the home to many foul things. It also has a long and evil history and currently is home to one of the fabled Witch Queens. The PCs must investigate and stop her.
The adventure itself is particularly original, but that doesn't make it less fun. There is a good balance of overland and dungeon exploring, plenty of new monsters to fight, a threat of an ancient evil. Given that this module is coded "A3" should give you an indication it is part of a larger series, and it is. It can be played as part of Troll Lords "A" series that began with "Assault on Blacktooth Ridge" and "Slag Heap" and continues in other Airhde products and adventures. But it can also be played as a stand-alone adventure.
The adventure is very reminiscent of the old Basic adventures of the early 80s, especially B2 and B4. In fact, it is almost a perfect mix of these two classic adventures. So in the nostalgia department, it gets a perfect score from me.
My biggest issue with the PDFs and the Print versions are the maps are fairly small. I can redo them on my own and larger, but having something I can print out or read easier would be nice.
The 5th edition conversion is good and really, C&C is so close to D&D5 as to almost make the conversion unnecessary, but still I did enjoy looking through both to find the subtle differences. The most interesting changes were to the Witch Queen herself.
The Witch Queen, Neb–Eprethat, is the central figure in this adventure and stopping her is the main goal. In the C&C version she is a Lawful Evil 5th level human cleric/wizard. In the D&D 5 version she is a Chaotic Evil 6th level human cleric.
All in all a really fun adventure.
