The Old Kingdom timeline is the oldest timeline. Going back to the earliest Empires ever assembled, right after their transition from being a City-State. Apart from being the most ancient, this time period is also the most hostile. It sustained some of history's most blood quenching conquerors the world has ever seen. Morning, noon, and night Saiyan rulers used to beg for carnage just to see their rural City-State rise from the ashes and become thriving war waging Empires.
