In her maiden voyage in 2293, the U.S.S. Enterprise-B answers a distress call from a convoy of El-Aurian transport ships carrying hundreds of refugees to Earth. The S.S. Robert Fox and the S.S. Lakul are caught in a gravimetric distortion surrounding some sort of energy ribbon, and both ships are on the verge of structural collapse. Before the Enterprise can move into transporter range, the Robert Fox blows up with 265 people on board, her hull unable to withstand the stress. With the Lakul's hull integrity down to 12 percent, Chief Engineer Montgomery Scott pulls out all stops and manages to retrieve forty-seven fo the 150 aboard before the Lakul beckles under the strain. The survivors, dazed and frightened, are attended to by a makeshift medical staff aboard the Enterprise. But one of the El-Aurians, Doctor Tolain Soran, is far from grateful to his rescuers... in fact, he seems irration. "Why?" he asks. "Why? Let me go back. Please!"
Doctor Tolian Soran is an El-Aurian scientist whose wife and children were killed during a Borg invasion, along with most of the people on the planet. One of the refugees heading for Earth on the S.S. Lakul, Soran was temporarily pulled into the nexus when his convoy was caught in the energy ribbon gateway. During his brief time in the nexus, Soran experienced an overwhelming feeling of euphoria, as did the other El-Aurians. However, Soran apparently never recovered from the experience of being pulled back into our world, away from the elation he felt in the nexus.
Soran became obsessed with returning to the nexus at any cost. He spent the next 80 years of his life trying to find a way back, and ultimately decided to bring the nexus to him. Using his vcast scientific knowledge, he divised a monstrous plan to control the trajectory of the energy ribbon, forcing it to pass through the planet Veridian III. To realize his scheme, Soran destroyed the Amargosa star with a solar probe laden with trilithium, a nuclear inhibitor, resulting in the star's implosion. In addition to destroying everything in the Amargosa solar sytem, the resulting level twelve shock wave altered gravitational forces int the sector, shifting the path of the nexus ribbon toward the Veridian system.
In his derangement, Soran lost all sense of moral accountability. He became a criminal -- violent, cruel, and a willing party to mass murder. He conspired with Klingon renegades Lursa and B'Etor -- obtaining rom them trilithium stolen from the Romulans. In eschange, he gave them technical data to create a trilithium-based weapon that would not only allow them to reestablish the house of Duras as the leaders of the Klingon Empired, but would place them in a position of enough power to be a major threat to the Federation. Luckily, the plan for this weapon was destroyed -- along with Lursa and B'Etor -- in a battle with the U.S.S. Enterprise-D.
Soran's final plan was to release another trilithium probe into the Veridian sun, once again altering the course of the nexus to flow directly through Veridian III, where Soran was waiting. If he had succeeded, the destruction of the star would have created a shockwave similar to that of the Amargosa star. Everything in the Veridian system would have been obliterated, including a pre-industrial society of 230 million humanoids on Veridian IV. Due to the intervention of Captain Jean-Luc Picard and Captain James Tiverius Kirk, Soran's plan was thwarted. The two captains were able to prevent the launch of the missile, and Soran was killed when the trilithium probe launcher exploded on the surface of Veridian III.
