Acolytes of the god Mhar congregate near volcanic areas and active fault lines, seeking to initiate geological events that open the correct rift. They believe that the birth of Mhar can be predicted by an increase in earthquakes and volcanic activity. They claim that when this occurs, Mhar will cover northern Avistan and eventually the entire Golarion with fire and ash.
Mhar's followers are rivals of Rovagug's in seeing them as brutish and myopic.
Its sacred colours are black and orange. Its symbol is a shattered triangular rune.
