I don't know why, but I feel the need to quote these statements.
There is truth in these words. Take from them what you will.
"Man lives in the sunlit world of what he believes to be reality.
But...there is, unseen by most, an underworld, a place that is just as real, but not as brightly lit... a darkside.
The darkside is always there, waiting for us to enter - waiting to enter us.
~ Narrator to Viewer(s), Tales From the Darkside

"We all have a star in our heart.
Darkness and light are always right next to each other.
Show a little fear or a drop of tear and the darkness will grow and start to attack, consuming the light.
... you must always keep the star in your heart shining strong to defeat the dark and evil souls.
That is your most important mission...
~ Queen Serenity to Princess Serenity, Sailor Moon
