I read a description of this in a pamphlet describing the various D&D settings that came out in 1998. But I no longer remember the title.
The module in question was a Dragonlance adventure, and the description said at least some of the action occurred on one of Krynn's moons- which one wasn't specified, but I suspect it was Nuitari, if for no other reason the 'evil' moon seemed a place where heroes would most likely battle hostile beings.
The description did say PCs on the moon would encounter living beings "made of wire" (sounds weird I know, but that's how my faded memory recalls it) and referred to the adventure as exploring the "strangest parts of the Dragonlance mythos".
Does anyone know the title of this adventure?
