Omen: A Reign of War is the definitive core of The Omen Saga. Reign is the largest Omen release of the saga, including additional rules such as feats.  As sons of Zeus, you stand poised to conquer all of Greece, but not without the blessing of the gods. To determine who shall rule the domain of man, the gods have devised a contest & lent their most powerful forces for the cause: pillage & raze three cities. When the carnage ends, only one brother will be victorious, while the other will fade into antiquity as just another half-god spawn of Zeus.
