Bolvak was a Jaridian who wanted to end the war between his people and the Taelons. He maintained secret contact with Da'an and eventually met him in a kind of summit where the two tried to merge. For an instant, they succeeded and were briefly merged into an Atavus but Bolvak's Core Energy became too hot and he was killed. Much of his core energy remained with Da'an; it was later estimated that Da'an had another thousand years left thanks to the botched merger, but the American Companion found this somewhat cold comfort.
