Tolian Soran

Doctor Tolian Soran was an El-Aurian scientist born on El-Auria around the late 21st century. During the Borg assimilation of El-Auria in 2165 all of Soran's family was killed. Soran was fortunate to survive the assimilation and escaped with thousands of other refugees.

In 2293, Soran was being transported to Earth with hundreds of other E;-Aurian refugees aboard the Federation transport SS Lakul. A few light-years out from Earth, the Lakul encountered the Nexus energy ribbon and Soran entered the Nexus and was greeted with his greatest dreams and desires. Unfortunately, he was ripped away from the dreamworld and beamed aboard the Excelsior-class USS Enterprise-B.

Unlike the other El-Aurian refugees, Soran couldn't come to terms with the fact that the dreamworld was gone, and spent the next 78 years formulating a plan to re-enter the Nexus. (TNG movie: Star Trek: Generations).
