Tryesharan Scout Ship
The Tryesharan Alliance is a race of beings that seem to originate from the Gamma Quadrant, although their exact homeworld cannot be found due to their nomadic nature. Little is known about them save for a vague story among some cultures, although there is a possibility that they even came across the early Rihannsu culture before they became what is now known as the Romulan Star Empire.
They are currently a hostile force in the Gamma Quadrant, and have been in several conflicts against Gamma Force, the Starfleet task force assigned to the sectors stretching out from the Bajoran Wormhole. (Star Trek: Chimera)
