Carlitina Semla was a Twi'lek woman who was employed by the Culpharm pharmaceutical corporation as the Galactic Republic neared its end.
Semla, who resided on the planet Cularin (the location of Culpharm's headquarters), held the position of head of Culpharm Security. Around 32 BBY, following the disappearance of some of Culpharm's specimen samples, Semla contracted the group known as the Heroes of Cularin.
Shortly thereafter, Semla spearheaded an assault by a Culpharm Security squad against the Genasys Security Division. This attack occurred in Gadrin, just outside the Natural shop. Semla's mission was to stop Genasys, a competing company to Culpharm, from finalizing an agreement with Higgie Sethven, a Cerean biochemist.
