How many characters are in "The Pit and the Pendulum"? Who are they?

The
characters of the "Pit and the Pendulum" are as follows. We can confirm only two, plus
an unknown number of captors and rats:

The
narrator: The narrator has no name, but he has been arrested and imprisoned by
the Inquisition and will be subjected to torture meant, ultimately, to kill him. He is kept in a
dark room with a deep, round pit in the center that is filled with water and rats.

His captor(s): These are shadowy, elusive figures, whose
existence is primarily confirmed by what they do while the narrator is passed out. He finds they
have left bread, water, and meat that he can eat. He also finds himself bound by straps to a
board. A pendulum, obviously set in motion by his captors, swings lower and lower, threatening
to slice through his body.

The rats: When he
rubs meat on his straps, the rats come and chew the straps off, which allows him to escape the
pendulum.

General LaSalle: At the end of story,
General LaSalle, who has come to liberate people from the Inquisition, saves the narrator from
falling into the pit and drowning.
