Tryst

Tryst was a xenozoologist who went on an expedition to collect and catalog flora and fauna from many planets in the galaxy. He used a Continuous Event Transmuter to gather samples and was accompanied by his assistants Della and Stott. The government used to sponsor him but this stopped with the galactic recession, so he took to smuggling vraxoin. After the Empress crashed into the Hecate, Tryst tried to frame the Fourth Doctor as the smuggler, but was eventually exposed and arrested.
