Doctor Kerrian was a male Human that led a Republic archaeological team that ventured into the Deep Cradle on the planet Voss. Unlucky, Kerrian and the entire expedition went insane; with only the excavator Lefry not sharing their fate because he had undertaken a Voss ritual that protected him from the influence of the Nightmare Lands. Later arrived the Barsen'thor and the mystic-in training, Gaden-Ko. Upon Lefry's request, the Jedi tracked Kerrian to retrieve his holojournal for information of that region; however all the effort of the Barsen'thor to cure Kerrian from his insanity went futile, and the Jedi was forced to kill the scientist.
