Star Charmer - Luna's Lullaby (Celestia's Lament)

[Briianz]

Moonlight... Starlight.... Darkness falls
From the shadows owls call
All this shall be yours one day
Til then sleep. Dream the night away.
Crickets chirping in the vale
Hear the song of the nightingale
All of this shall be yours soon
Til then,sleep we shall raise the moon.
Such a song unto you was sung
long ago when we two were still young
Now, although you're no longer with me...
I can still hear that old melody
Lalalu,lalalu
May this song reach your heart
Even now as we drift father apart
Lalalu,Lalalu
You were sent from my sight
When your heart grew darker than your night
Ponies that play by the day
Sleep so soundly as it fades away
"Does not matter" you would lie
But I knew better than that, didn't I?
I could see a darkness in you
But I did not know what I could do
For what wisdom could I ever say-
-when all I truly knew was the day?
Lalalu,lalalu
May this song reach your heart
Even now as we drift father apart
Lalalu,lalalu
I still regret that day
when I had to send you away
That darkness's origin...
Did it truly come from just within?
A creature bringing terror and doom
A nightmare from the moon...
Lalalu,lalalu
May this song reach to you
Not that evil creature,
But the filly you were
Lalalu,lalalu
I have longed mourned  for you
And all of the things
I was forced to do...
Lalalu,lalalu
May this song reach your heart
Even now as we drift father apart
Lalalu,lalalu
In a flash you were gone...
All I had was a memory and a song...
All I have is your memory and a song...
