Pheromone enhancers were technologies implemented to modify pheromones inside the honeymoon suite located within the Grand Regent hotel situated on Lanz Carpo. During a mission to the planet for the Rebel Alliance, Leia Organa and Han Solo received access to this honeymoon suite courtesy of District Advocate [Dar Champion]; this access was leveraged by the rebels to gain entry into the hotel. As Organa and Solo were being shown to the suite, the droid intended to ignite the pheromone enhancers, a plan that was met with resistance from both rebels.
