The majority push for a religious focus, while a smaller group push for a scientific one. Fearing extreme persecution, the small Alteran group choose against using technology which could brainwash their brothers and depart in a ship for a galaxy to call their own. The scientific Alterans will henceforth be known as Ancients. ("Avalon, Part 2;" "The Fourth Horseman, Part 1;" The Ark of Truth)
