Parseltongue

Power hungry Slytherin
loved those of great ambition.
- sorting hat in Goblet of Fire in his song

In Slytherin you'll make
your real friends,
Those cunning folk use any
means
To achieve their ends.
-sorting hat in Philosophers Stone in his song

There is no good and evil, there is only power and
those too weak to seek it.
