Dungeon Master: "As you walk down the corridor, you begin to get the feeling that something is following you..."
Player: "I turn around, holding my sword at the ready. What do I see?"
Dungeon Master: *rolls a die* "You almost don't see it at first, as it is nearly transparent, but down the corridor near the door you came through is an Ildriss. Roll for initiative."
