The Cult of the Dark One (also known as the Cult of Amon Tillado) was a secret cultist society mentioned in Quest for Glory: Shadows of Darkness. Its followers worshiped the Dark One Avoozl. The cult was founded by The Mad Monk Amon Tillado, who build a monastery dedicated to Avoozl in the Town of Mordavia. Some say those cultists became the disfigured monsters known as Chernovy, wandering the swamp area at night.
