And... really... are you telling me that in all the D&D games you have ever played, that the Orcs or Goblins never had a chieftain? That the Fire Giants never had a King? That the last thing you had to fight in the course of the adventure was likely an Ogre or Red Dragon or something else that was bigger than what you had fought through on your way to get there? That never, not even once in all the adventures you played, that not a single one of them ever involved a name villain or target who had done or was planning to do something and needed to be killed before that time came to a close?
That no adventure that you played EVER had anything remotely like this with an encounter with a creature that was likely a bit higher level than anything previously and once you defeated it, the adventure could wrap up pretty neatly because often there would be no more challengers?
