The Traya Nall was the ship name Professor Sonek Pran gave to Thal Orbital Control, when in 2381, he visited the planet Thalezra aboard the USS Seine. The runabout had altered its shields to be read as a Lissepian planet-hopper, rather than a Starfleet vessel. Pran also used the alias Kom Traya for himself, claiming to be owner of the Traya Nall.
