Blinding Evil

A horrible evil is after the main character.

                I am in slumber.

        I bring peace and tranquility.

      But it brings only dread to me.

          It blinds those you see it.

            It chases me from sleep.

      I can only exist when it does not.

When others stand against it,I can appear.

          It blinds many to the truth.

          We were once a balance.

But now it has taken the identity of heroism.

        While am seen as a villain.

            I am called Darkness,

                The evil,is Light.
