Rojan's ancestors originally began the voyage in multi-generational spacecraft centuries before, and by the time the ship reached the galactic barrier in the mid-2260s, Rojan had become leader of the group. Unfortunately, the Kelvan spacecraft was destroyed during the passage through the barrier; Rojan and four others were able to escape to a nearby Class M planet. In order to adapt to the environment around them, Rojan and the others established a humanoid form.
