excerpt from
Bretonnia-sourcebook,
Book4a-Religion, p16
For obvious reasons, Sigmar is not a popular or significant deity in
Bretonnia. Bretonnian scholars have often argued that Sigmar was not a
genuine god but rather a saint of Ulric (an opinion repudiated by both
the cult of Sigmar and that of Ulric). The cult is found only in a few
villages near the border with strong populations of Imperial emigrants,
and in Guisoreux, which has the only temple of note in the kingdom.
Imperial mercenaries and emigrants are the main worshippers within
Bretonnia, forming a very unstable body of worshippers. At various
points the cult has been proscribed, its followers declared spies and
traitors, hunted down and executed. However, at present the cult is
officially tolerated, though worshippers are still regarded as
potential Imperial spies by the common people.
