Ok awesome! One more question are the races for the npcs the same as the player characters or can you be a race that a player character cannot be. For example if a goblin is not a player character option can you be a goblin as an NPC?
You are correct. NPCs will usually be the "monsters" that are sent out to fight the PCs. Sometimes an npc will be a towns person looking for help or something like that. The npc is to help the staff of the chapter run the game and entertain the pcs.
