A Talarian freighter found crippled near the Neutral Zone in 2364, from which the Enterprise-D rescues three Klingon renegades moments before the ship explodes, in the episode Heart of Glory.
The Batris is a Talarian cargo ship that appears in the first-season Star Trek: The Next Generation episode Heart of Glory. In 2364 the Enterprise-D finds her drifting and badly damaged near the Romulan Neutral Zone, with her hull close to breaking up.
Riker, Data and La Forge beam aboard, and the bridge crew watch the search through a link to La Forge's VISOR. They find three Klingons, Korris, Konmel and the dying Kunivas, and get them off just before the freighter explodes.
Korris claims they were passengers who helped fight off a Ferengi attack. In truth the three had seized the Batris and used her to destroy a Klingon cruiser sent to bring them back, because they rejected the peace between the Empire and the Federation. Their attempt to win Worf to their cause drives the rest of the episode.
