Reasons Why Lwaxana Troi Should Be The Federation's Ambassador To The Dominion
  • Much of the Dominion’s postwar policy towards the Federation is going to be informed by Odo, and she’s the only one in the Diplomatic Corps who has ever positively interacted with him before.
  • She’s a telepath, so she can see through the Vorta’s bullshit and know when changeling spies are infiltrating the embassy.
  • Her plain-spokeness would probably be appreciated by the Founders.
  • Her planet was occupied during the war, so she knows first hand what the stakes are.

The Vorta were a species that had to be created very quickly to fill a specific need: the Founders’ managers, a bureaucracy that facilitated the will of the Founders. At the same time, the producers didn’t want an elaborate alien makeup, just an instantly recognizable humanoid creature who would interact with the Federation personnel as well as with the Founders/changelings and the Jem'Hadar. "Don’t spend a lot of time with a new face,” the producers told makeup. “Just do something with the ears.” Accordingly, a set of large, extended ears that didn’t look too bizarre were designed, and combined with a pale skin tone to create an ominious and menacing look. Then, as a finishing touch, makeup came up with the idea of purple contact lenses for their eyes, highlighted by a lavender eye shadowing. The hairstylist worked up a hairstyle to go with the pale, slightly purple tinge. Female Vorta had smaller ear appliances to differentiate them from their male counterparts.
