Welcome to Dark Reflections, a sandbox campaign module for Warlock!, the roleplaying game based on the early days of British tabletop gaming.
This book contains the history, factions and major players in the campaign, plus numerous adventure sites and expanded rules. In Dark Reflections, the adventurers find themselves in the middle of a shadow war that spans multiple worlds and dangerous factions. Will they ally with the mysterious queen, or with those that seek to oppose her? What will they find in the depths of Ruined Honheim? Open this book and find out.
The outcome of this campaign is not predetermined, but will vary greatly depending on which faction the adventurers support.
To get the most out of this book you will need a copy of the Warlock! core rules, and while not essential, a copy of Kingdom, which details the implied setting of the game and will make the campaign more immersive and enjoyable.
