Familiarus was a vorox who was smarter than all the rest. He wanted to do something better than just maraud oncoming caravans. So he ventured out into the glatorian arenas. Once there he was accused of being to primitive to fight with the civilized glatorian so he jumped into a pit and started fighting to show the agori that he was capable. He is now a true toa and lives on metru nui and is practically worshipped by his agori/matoran.
