Storyteller
From World Of Darkness Wiki
The Storyteller is, to the the World of Darkness, what a Game Master or Dungeon Master is to other game systems. She is the one who develops the specific game world which a troupe of players experience through their characters. She creates the overall milieu within the context of a World of Darkness game (Vampire: the Requiem, Mage: the Awakening, etc.). She develops the non-player characters, from bad guys to the casual acquaintances the characters meet and interact with. She writes the story line: the hooks, the plots, sub-plots, red herrings, macguffins, and everything else that will intrigue, involve and endanger the characters. Then she initiates, controls and adjudicates the ongoing scenario from start to resolution.
