Black Roses

The Black Roses, also known as the Tormenta Guild of Assassins, is a clandestine illegal organization that specializes in covert operations and assassinations and has close ties to the Admiralty of Tormenta, prominent aristocrats, and other secret societies. The guild is colloquially referred to as the Black Roses due to the presence of a single black rose left on the bodies of successful hits.

Structure
Despite their name, they are not limited to activity in the Commonwealth of Port Tormenta, and are composed of various cells that operate independently in whatever area of the world they are in, being led by a Lead Petal (a cell leader), which all report their zone activities back to the infamous and mysterious Grandmother of Assassins, which reportedly lives in Port Tormenta.
