* WhatCouldHaveBeen: A planned sourcebook for the standalone ''Iron Kingdoms'' RPG covering Ios, Rhul and Cryx (and the Skorne Empire, before it got expanded into its own book) never materialised before the RPG was discontinued; these nations would subsequently appear in ''Borderlands and Beyond'' and ''The Nightmare Empire'', two sourcebooks for the ''TabletopGame/DungeonsAndDragons'' 5th Edition version. Similarly, publications covering gargantuan warbeasts in the RPG (other than the desert hydra, mammoth and woldwrath) only existed as a teaser in ''No Quarter'' issue 63.
