 Even this slow and laborious process came to a complete halt in April 2004 when Gygax suffered a serious stroke. Production came to a halt due in part to Gygax's health, so Gygax put together a team of people to continue with the creation of Zagyg background material. Although he returned to his keyboard after a seven-month convalescence, his output was reduced from 14-hour work days to only one or two hours per day. Kuntz had to withdraw due to other projects, but he continued to work on an adventure module that would be published at the same time as the first book. Under these circumstances, work on the Castle Zagyg project continued even more slowly. The Castle Zagyg line kicked off with CZ1: Castle Zagyg Part I: Yggsburgh (2005), a 256-page book. This 256-page hardcover book contained details of Gygax's original city, its personalities and politics, and over 30 encounters outside the city. Later that year, Troll Lord Games also published Castle Zagyg: Dark Chateau (2005), the adventure module written for the Yggsburgh setting by Rob Kuntz. Jeff Talanian helped with the creation of the dungeon, eventually resulting in publication of the limited edition CZ9: The East Marks Gazetteer (2007).
