In The Emperor’s Name (also known as ITEN) is a set of rules for skirmish games set in the Warhammer 40,000 universe created by Games Workshop. ITEN allows you to create narrative games inspired by the adventures of characters such as Gregor Eisenhorn, Gideon Ravenor or Shira Calpurnia, or any of the millions of Inquistors, Arbitrators, Roque Traders, Explorators and other personalities of the Imperium — as well as their enemies, be they Xenos or Chaos.
The Forge Of War Development Group is a group of wargaming enthusiasts who work together to create great wargames rules. As well as ITEN, Forge Of War has also produced FUBAR, a one page set of RPG/Skirmish Rules with conversions for many different scales and settings.
