In this episode Eric gets to be the Dungeon Master, as the diminutive dome-head takes a much needed rest. After spending 17 episodes griping and whining about the Dungeon Master, Eric the Cavalier, gets to don the robes and all the powers that come with it. He also learns how hard it is to actually be the DM and how his powers can affect more than he knows. 

At first Eric is quite enthusiastic about it, as this means that he is powerful and also that he gets to try to find a way back to his homeworld for himself and his friends. This means getting to the town of Darkhaven and obtaining the Golden Grimoire that will teach him how to control DM powers. 

Of course Venger comes into the story as well, trying to stop the gang from going back home and, as per usual, attempting to steal their magical artifacts for himself. Of course the real Dungeon Master comes back in time to save the day and Eric is released from too much of a good thing, but not without retaining some powers (I wonder if that will be relevant in future?)
