does anyone know where this quote might be from?

in my art room at school i saw a phantom of the opera painting with a quote written on it, and it's really bugging me that i don't know what it's from!! can anyone tell me?

"my kingdom lies in eternal darkness...darkness and silence have been my companions since the day i turned my back upon the world and created an empire that was solely mine. from the moment of my birth my destiny was to be alone" -Erik
