The Grey-Nil act as Black Tide's clandestine law enforcement. They gather intelligence on dissenters, monitoring for potential troublemakers. Upon conquering foreign territories, they pursue and imprison or eliminate leaders, clerics, royalty, and other possible threats that could jeopardize control over the populace.
The Crimson Cult's most heinous act occurred during the Black Tide War (1465 - 1486), when they ruthlessly eliminated all members of the Farinteen family, thereby extinguishing five centuries of hereditary dominion over the Farinteen Dynasty.
