Gideon Seyetik was a famous terraformer who was also an accomplished artist and chef. He successfully terraformed Blue Horizon, New Halana and many other planets, but had never been able to do the same with Venus. He had worked with Pascal Saadya prior to 2370.
In that year, Seyetik travelled to Deep Space 9 aboard the USS Prometheus with his wife Nidell. Seyetik's objective was to reignite Epsilon 119, a dead star near Bajor, using protomatter. He thought it would be the crowing achievement of his career, making terraforming planets seem like "childs play".
After he realized his wife Nidell was unhappy in their marriage and that she would never leave him due to her people's beliefs on marriage, Seyetik used one of the Prometheus Type-15 shuttlepods to fly towards the sun. Just before it crashed into the dead star, Seyetik asked Benjamin Sisko to send his written obituary to the Daystrom Institute. His last words were "Let there be light!" as his shuttle hit the surface, igniting it and bringing it back to life. (DS9 episode: "Second Sight")
