TRAVELLER® | Science Fiction Adventure in the Far Future

An historical Sword Worlds campaign setting

"Another excellent option open to allow exploratory adventuring is available to those willing to step part of the way out of the Traveller universe.  You can still use an awful lot of the material developed for the Traveller universe in doing so—just set the adventure in the 'past' (that is, prior to the 1100s in which the published material takes place)."

The Space Viking Era

The Cleaved Helm is an unofficial "Alternate Traveller® Universe" (ATU) campaign setting for the classic science-fiction role-playing game, set among the setting-historical Sword Worlds of the 2nd Century pre-Imperial.  This is the period of the Sacnoth Dominate when the inhabitants of the original twenty Sword Worlds are expanding into interstellar space and is most akin to the Sword-Worlds setting of H. Beam Piper's Terro-human Future History novel Space Viking, an inspiration for Traveller's Sword Worlds.

The Space Viking Era is a time before the arrival of the iconic Third Imperium in Sword Worlds space (indeed the Third Imperium has yet to be established).  The Sword Worlders have just begun to interact with the Darrians to spinward and have only limited trade with the Zhodani to coreward beyond the Entropic worlds.  Recently, formal and informal exploring expeditions to the trailing, rimward and coreward frontiers have opened these regions to Sword Worlds exploitation and settlement.

Here you will find information about the history of the Space Viking era—History—and about the worlds of the Sacnoth Dominate (and beyond).  There are library data entries for the Cleaved Helm campaign—Library Data—and Ref's Notes guidance on backround elements of the campaign.  There are pointers to canonical—and apocryphal—sources of material for the campaign.

There are also in-setting news briefs from Anderspress News Service, a major news provider in the Sacnoth Dominate.  There are ready-made adventure scenarios and descriptions of non-player characters who may be encounted in the Cleaved Helm campaign.  You can also follow the Sacnoth Dominate's Exploring Expeditions as they venture into the Sepireld, Pilgrim and Danuuz frontiers.  Welcome to the Space Viking Era!


The Cleaved Helm is dedicated to the memory of Hans Rancke-Madsen.  I didn't always agree with Hans but I always appreciated his civility, admired his creativity and respected his dedication to Traveller.
