I didn't write it with the Slayers in mind, but it still is pretty decent, so...
What is this pain that beats inside,
My once proud heart?
What is this longing that tugs,
On my weary soul?
Can I name this emptiness,
That stirs the flame of sorrow?
When the moon shines down bright,
Its light hits an empty soul.
I am but a shell holding the smallest part,
Of something bigger than man can dream.
A part separated from the Whole of it,
Longing to be made whole.
The name of this feeling,
This pain oh so deep.
That rings through while I'm wake,
And calls in my sleep.
Is one thing, and one thing alone,
Loneliness
