Guild Member Installments were started in the early days of Judges Guild. They were sent to subscribers, who in effect, became "Guild Members". There were a total of 26 installments which were labeled as I through W and 15 through 26. The lettered installments came with rules, maps and other play aids and were some of the earliest incarnations of Judges Guild modules such as: Modron, Tegel Manor, and The Thieves of Fortress Badabaskor, all of which became Judges Guild classics and collector's items. The numbered installments generally came with a module or book. They also included the corresponding Judges Guild Journal. As an example, Installment K was shipped with Journal K. All of these were shipped in a Judges Guild envelope.

The installments listed on our site will not include the original mailing envelope unless otherwise noted in the condition note for the individual product.
