Secret of the Slavers’ Stockade (A2), softback adventure for AD&D 1st edition, by Harold Johnson with Tom Moldvay
“The battle against the slavers continues! You and your fellow adventurers have defeated the slavers of Highport, but you have learned of the existence of another slaver stronghold, and you have decided to continue the attack. But beware! Only the most fearless of adventurers could challenge the slavers on their own ground and live to tell of it!
This module was originally used for the official ADVANCED DUNGEONS & DRAGONS™ Tournament at Gen Con® XIII Convention and is the second of four in a series of related tournament modules from TSR Hobbies, Inc.
This module contains a challenging scenario, the tournament recording system plus nine pre-rolled, playtested tournament characters. Also included are large scale referee’s maps, notes, and background information. A2 is a complete adventure in itself, but it is also a companion to A1 (Slave Pits of the Undercity), A3 (Assault on the Aerie of the Slave Lords) and A4 (In the Dungeons of the Slave Lords). Be sure to look for other exciting adventure modules from the Game Wizards of TSR.”
