In the 24th century, Kaelon scientists discovered their sun was dying. Timicin devoted his life from 2327 onward to developing a method of revitalizing it. It would take the form of torpedos which stimulated the sun in various ways including helium fusion enhancement.
As Timicin finished his method, the Kaelons turned to the United Federation of Planets for help in 2364 to find a star to test his method. In 2367, they found the Praxillus system. The Science Minister, B'Tardat, approved Timicin to board the USS Enterprise-D and conduct the experiment. At first, the experiment seemed successful, with a stable stellar temperature of 220,000,000 Kelvin reached momentarily, but the sun's temperature continued to rise to dangerous levels, forcing the starship to evacuate the system and return to Kaelon II.
While on board, Timicin became involved with Lwaxana Troi and fell in love with her, finding her a "vibrant" and very kind person. He wished he had met her earlier, as he was soon to undergo the Resolution in which he would commit suicide. Lwaxana convinced Timicin to reject the Resolution. Timicin at first refused to do this, but reconsidered when he discovered how close his research had brought him toward saving his planet's sun. Investigating convection boundary uncoupling and hydrogen-alpha emissions, and having considered shock wave delay at the stellar surface, Dr. Timicin found that he needed to account for neutron migration in his calculations, which already included the deep convection patterns, the proton reactions, and the neutrino count. Timicin surmised it would take others decades to familiarize themselves with his work and possibly save the Kaelon sun, something that would take him only half the time.
With this in mind, he asked Jean-Luc Picard to grant him asylum aboard the USS Enterprise-D. The planet's authorities dispatched warships and ordered them to fire on the Enterprise-D if the ship left with Timicin, and cut him off from making any further transmissions about his project, refusing to listen to him even if he perfected his experiment. Timicin's daughter Dara transported aboard and pleaded with him to accept the Resolution and his world's traditions. Timcin was swayed by his daughter's words, and withdrew his request for asylum and returned to Kaelon II to perform his Resolution, accompanied by Troi. (TNG: "Half a Life")
