A Troglyte miner and leader of the Disruptors, who fight for the rights of the miners against the city of Stratos.
Vanna is a Troglyte who works as a servant in Stratos and leads the Disruptors, a group of rebel miners on Ardana. In The Cloud Minders she seizes Kirk to win concessions for her people and distrusts him as just another ally of the city dwellers.
When Kirk learns that zenite gas impairs the miners' minds, Vanna becomes the person he must convince that the masks he offers will help. She helps him deliver the zenite and gives the Troglytes a voice in their future. She was played by Charlene Polite.
