In Star Trek V, Sybok mentions Vorta Vor, the Romulan paradise or original place of creation. Assuming the perspective of the Jem'Hadar, the Vorta play a similar role: By supplying them with Ketracel White, they are the guarantors of existence and hence provide them with the prerequisite for life.
While Vorta Vor is the place of original creation, the Vorta grant the continuity of creation. Given this shared motif and the striking similarity of names, I wonder if there is any connection between the Vorta and the Romulans.
