The use of Fidelio as the password to get into the Masked Ball is an example

of a literary device known as foreshadowing, a term referring to clues that provide a glimpse of what is to come.

On the Wikipedia website, Fidelio is said to be a story of a woman who rescues

her husband from death in a political prison.

The Masked Ball is exactly that, as Harford comes to be threatened by the man in the red cloak;

it should also be noted that the high-priest who carries out Illuminati black magic rituals also wears red,

a color symbolizing the bloodline that is of paramount importance.

Just as his situation appears rather grim, Dr. Harford is suddenly saved by a mysterious woman,

who sacrifices herself at the last moment.

Because the Illuminati are extremely political, this was a rescue from a political prison of Dr. Harford’s own making.

As Dr. Bill Harford arrives at the masked ritual, he gives the password, Fidelio,

which as we are told in the film, is the name of Beethoven’s only opera.

He has to pass through seven people to enter what the DVD calls THE ABYSS.

This is certainly interesting, as it may be symbolic of the Seven Gates of Hell -

-- or the seven rings that surround Dante’s Inferno --

- which are themselves, symbolic of the Seven Gates of Hell.

There were two men outside of the house, one man at the front door,

one man in the vestibule (where Harford gives the password a second time),

another man takes his cloak, one man stands at the inner door,

with the seventh masked man standing directly outside of the ritual itself.
