How did the world become a stranger place ?

Upon times and long time ago even before hours and years didn't have a value, lived humanity a simple life into small kingdoms.
But wherever you go.. the same rule leads
"The weak serves the strong" people lived under this title for times until "weaks" became acting like slaves and "strongs" like superiors over anything and anyone
Will that change? Yes everyone knows life changes but how ? How will that turn better ? Will "normal " people stand against " nobles" ? Will be there a day a fair king comes to the throne? Or maybe a new dawn of civilization , Dragons appearing ? Vampires? Beasts looking like actual humans? Those creatures only heard in legends! Can that really do something! Who knows....
