Cayenne works as a servant to Burdock, the owner of Greenthumb Gardens' herb garden. She is in love with Dill, Burdock's son. However, he is in love with Lavender who, in turn, is love with Carraway. One day, a Gray Rain falls on the residents of Verdham. This is caused by Rainiac.
After the party defeats the Rainmaker, they use the Angel Tears and the residents return to normal.
After Pepe recovers, they hold a feast to celebrate his recovery. Cayenne cooks all of Dill's favorites for the party. While everyone is enjoying the food, she talks with Pepe outside the party. She tries convince him to elope with Linda in order to get rid of the competition for Dill's affections. He refuses, stating that it would just cause trouble for his family. After it rains, Cayenne is disappointed that the rain will wash the poison away. She tells the party that it is a joke, which causes Ruff to say that it isn't funny to joke about poisoning food. She returns to Borlock's house. Inside, Dill and Cayenne are talking about Lavender when suddenly, she kisses him. Dill removes himself from her embrace. Cayenne spits out that this is probably what Linda and Pepe are doing but he refuses to believe it. When Pepe leaves town, Cayenne is disappointed that Pepe didn't take Linda with her.
Dill loses the mansion to Kadasol. Cayenne marries Kasadol and becomes lady of the house. She still has feelings for Dill, shown by Cayenne paying off his bar tab. Unbeknownst to Kasadol, Cayenne has been poisoning Kasadol slowly with an addictive poison, putting it in his food. This has been disguised to the other villagers as tending to her sick husband.
30 Years Later
Cayenne is preparing her husband's meal as usual when she puts too much poison in his food. Believing that someone would get suspicious if Kasadol dies too quickly, she has her maids throw the food away. She goes to see Dill. She tells him that she still loves him, but Dill won't hear of it. Dill says that she has a good life and she shouldn't throw it away because of him. Cayenne says that she isn't doing this for Dill's sake but for her own. He notices the rope holding a vial.
Cherri, one of the housemaids, believing that it would be a waste of food, feeds Cayenne's cooking to her dog, Kopan. When Kopan eats it, he becomes poisoned. Cherri brings it to the attention of Cayenne who becomes indignant at the fact that she would deliberately poison her husband. She resolves to fire Cherri later in the future.
Cayenne walks out of the mansion. As she does, the string holding the vial of poison breaks. However, Cayenne doesn't notice. She continues to Dill's house.
Cayenne prepares lunch for her husband, laced with poison. Kadasol is about to eat when Cherri comes in and tells the master of the house that the food is cooked with poison. Kadasol refuses to believe that it is poison but Cherri gives proof. She shows him the vial which Cayenne always carried. Kadasol notices it as the vial which Cayenne told him was medicine. Cayenne denies the accusations but Kadasol tells her to drink the contents of the vial to prove her innocence. It is at this point that Dill comes in. He tells Kadasol that she poisoned him on her orders. Kadasol throws both of them out of the house. Dill motions for Cayenne to come with him and the two leave town, never to be heard from again.
