The Dungeon Master
From Startroid
The functions of DM are these:
- Adventure Phraser: The DM creates the groundwork wherein your adventure can take place, including settings, important NPCs, factions, and dungeons.
- Narrator: The DM is your means of perceiving the game world. If you don't know where you are or what things look like, ask.
- NPC Behavior: The DM acts out or otherwise expresses all NPC dialog and actions.
- Monster Behavior: The DM makes all decisions for enemy combatants.
- Referee: The DM is responsible for applying relevant rules, as well as determining outcomes not explicitly covered in the rules.
The DM is not your opponent.
