This is the latest incarnation of the original castle and dungeon complex, Castle Greyhawk. As that name is now the property of another entity, the new material herein that is drawn fron the old has a different name now, Castle Zagyg, for none other than that Mad Archmage Zagyg caused the construction of the place in its original form. The work began with a single dungeon level in the late autumn of 1972, with the first exploration party being composed of characters created by my eldest son, Ernie, and my eldest daughter Elise. The very next day they adventured again accompanied by Rob Kuntz, my co-designer herein, and his brother Terry, as well as my friend don Kaye. As play was so intense I went to work immediately that night to create a second level, and to those two I added a new deeper level every few days. By the beginning of 1973 there was a map of the ruins of the upper works of the castle and eight levels beneath them. When summer came, the whole complex consisted of 13 levels of dungeons. Those served well for the dozen regulars who were playing in the campaign, but as there was a constant influx us new players who would create characters and adventure for several sessions, then go forth to establish their own campaigns, the dungeons population of monstrous inhabitants was becoming depleted. I added a few side levels, but I couldn't keep up with work and play demands. Troll Lord Games is proud to bring you Gary Gygax's original castle adventures.

A strange cloud lifts just west of the Urt River, revealing a place of legend, a monument of dread, known to the ancients as Castle Zagyg! But who constructed this mysterious place and had it enshrouded in the mists of legend? Indeed who now parts that curtain and for what reason? What lurks within its empty towers and strange dungeons? Certainly this is no ordinary invitation to adventure, but one so ancient that the treasures and magic within its catacombs and hallways must be those made by the gods themselves, for who else could contrive such a monument but a mad deity? All manner of creatures infest the upper works, crawling through its twisting holes and tunnels, nursing an ancient hurt and glorying in an evil they only hope to vomit onto the lands. Castle Zagyg's Upper Works is a Castles & Crusades mega-adventure for characters levels 1-4. It is strongly suggested that adventuring parties contain at least one thief and be prepared to encounter all manner of dangers in the haunted ruin and in the subterranean mazes beneath the earth.
