If you are willing to think outside-of-the-box, find a copy of the score to Mozart’s last major opera and check out the character Monostatos. Take a moment to figure out how this character tries to take fate into his own hands, and lead the noble vision of Sarastro and his priests astray. How does Monostatos try to influence Pamina?
In the opera, Sarastro promptly removes Monostatos when he realizes he is a traitor. The temple is preserved, the knights are safe (until the final battle). What if Sarastro were to have allowed Monostatos to remain in the temple? What would have happened then? Would the priests have been destroyed and Sarastro be out of a job?
