- "Fear drives people to seek out all manner of protection. God, the Invisibles, the lwa. But sometimes that is not enough."
- — Cassandra
Cassandra is the leader of the Haitian Mob in New Bordeaux, and an Underboss in the Clay Crime Family. When Baka, who was widely thought to be the leader of the the Haitians, is killed by Lincoln, Cassandra emerges as the group's true boss. 
Very little is known about her early years, though she mentions to Lincoln that she had a sister who was murdered by Ritchie Doucet and the Dixie Mafia. This is later revealed to be untrue, as Caroline is actually her daughter, not sister. She forms an unlikely alliance with Lincoln, and together with Thomas Burke and Vito Scaletta, becomes one of his underbosses in an effort to take down the Marcano Crime Family.
She's as ruthless as she is mysterious, but one thing is for certain: The Haitian mob's alluring "Voodoo Queen" will destroy the human trafficking trade in New Bordeaux, no matter the cost.

Nothing is known of Cassandra's fate if Lincoln decides to stay and rule New Bordeaux. If she and Lincoln managed to get through the takeover of the Marcano Crime Family without any betrayal, it is assumed she continued to lead the Haitian Mob and work as Lincoln's underboss, running whatever territories Lincoln saw fit to give her.
If Lincoln leaves New Bordeaux and Cassandra assumes control of the city, there wasn't a crime boss from Boston to Miami who respected her claim. As a result, the Commission, the Columbians, and the Cubans all went after her. They realized too late that they had no idea who they were fighting.
Johnny Galante had his throat slit while watching Deep Throat in a porn theater. Manny Moreno was set on fire outside his daughter's quinceanera. Severo Garcia was buried alive on the beach and drowned when the tide came in. Anton Bagrov was beaten to death with crowbars in the parking lot of the Briar Patch.
After this the real criminals came after her. The governor declared martial law and sent in the National Guard, so Cassandra shot him in the head on the steps of the capitol building. After that everyone got the message: The city belonged to Cassandra. But the government is like a rogue elephant. It's murderous, patient, and never forgets. So the state pulled funding for schools, city maintenance, and the like. If they couldn't get Cassandra, they'd strangle the city until it gave her up.
When the hurricane hit New Bordeaux, the locals called it Hurricane Cassandra. Nobody expected the damage to be so severe that the levees would completely fail, that the flooding would wipe out half the city and force the other half to leave, that the city would turn into the ghost town it is today. It's hard to believe that a major American city would be left to rot like that.
Some say that Cassandra was one of the thousands who drowned in the flood. Others say she slipped away into the swamps and still rules what's left of the city's underworld from the bayou. Either way she's a ghost who hasn't been seen in years.
