Mona hasn't heard the name "Monique" in so long that she would probably laugh if addressed as such. Mona is a substantial woman with an effervescent personality that pops out in loud bursts of joviality. Mona's mother was of a similar make, but with a more serious side. Mona has always attributed her mother's more somber nature to her complete immersal into voodoo. While her mother taught Mona much about voodoo, she also warned Mona of the negative consequences for delving too deeply into the arts as she did. Mona took her mother's advice to heart, and strictly limits her direct voodoo involvement to operating her shop just off Rampart Street, where she sells her own concoctions of gris-gris and other voodoo paraphernalia. Of course Mona has close ties to the shakers and movers in the voodoo community, such as Dr. John and Julia Jackson, who actually come to Mona's shop to purchase the harder to find voodoo supplies and artifacts or for casual chitchats. Officially Julia and Mona are fierce competitors for the same market, but privately the two are amiable enough, because they cater to different clientele: Julia serving the mid to upper class while Mona deals with the poorer folks.

Mona makes forays into the bayou with her one employee Jaques Cormier, to find the freshest possible ingredients and items, and what she can't find locally she contracts via a long time acquaintance, Jean Picard, who secretly smuggles in the illicite goods.

Mona is quite a large woman and loves to wear garishly colored dresses with floral prints. The less reverent "Mona the Moomoo Queen." Mona believes in the power of voodoo, and is superstitious, and tends to avoid many modern inventions, although necessity will see her take a car or motorboat ride. Mona's shop and apartments are illuminated by gas rather than electricity, and she has no telephone.

Eleven years ago Mona's mother brought a young child from the bayou to live with Mona. Simoné's parents had disappeared from the bayou, and Mona's mother knew something of the incident, but refused to say a word about it, so Mona has cared for Simoné as her own child all of these years.

Mona acts as mother to many of the jazz musicians who play in the dives along Rampart Street. Her personal favorite from this group is Nick Jolson, a brilliant trombone player from Memphis with a big heart (or so Nick claims, but Mona suspects there is some tragedy in Nick's past that he's hiding from). Mona is also something of a matchmaker, and has paired Simoné and Nick as a couple, whom, with a little push or two from her, are coming along nicely together.

Mona lives in the apartments above her shop, where she is quite content and comfortable. She lets out a few rooms to Jaques, but still has more than enough space for her own significant needs. Mona makes enough money to get by, but some extra cash would come in handy to expand her store and revamp her apartments.
