This is a spinoff of the song "Lullaby for a Princess" but I changed quite a few of the lyrics to make it in Luna's POV.

The lyrics I wrote myself will be italicized! And the original lyrics by Ponyphonic will be normal text! (Please note that I added my own words in the middle of some lines, so the whole line will be italicized!)

Fate has been cruel and order unkind
How could I have given it its might?
The blame was my own; the punishment, yours
The harmony's silent tonight

But into the stillness you'll bring me a song?
And you will my company keep?
Till my tired eyes and your lullabies
Have carried me softly to sleep?

Once did a pony who glowed like the moon
Look out on her kingdom and sigh
She frowned and said, "Surely, there is no pony
Who loves me, and my beautiful night sky"

Her sister's great reign and the sunlight's great glory
Created the shadow she cast
Which fell dark upon me, the sister she loved
And grew only darker as days and nights passed

Tia, sun princess, goodnight sister mine
And rest now in moonlight's embrace
Bear up your lullaby, winds of the earth
Through cloud, and through sky, and through space

Carry the peace and the coolness of night
I'll carry your sorrow in kind
I know that I'm loved so much more than I knew
I forgive you for being so blind

"Tia, my sister, why can you not see
That I haven't been given my due?
Why are you ignoring my begs for attention?
I'm lost in the darkness, really missing you!"

But such is the way of the nightmare, it sweetly
Takes over my mind; I'm its host
And you, foolish sister did nothing to stop
The destruction of me when I needed you most!

Tia, sun princess, goodbye, sister mine
'Til the day I am finally set free
Bear up your lullaby, winds of the earth
Through cloud, and through sky, and to me

All that I wanted was pony's respect!
Nightmares now control my mind
Now that I know I'm loved more than I knew

Troubles will be far from my mind
And I forgive you for being so blind

The years now before us
Fearful and unknown
I never imagined
I'd face them on my own

May these thousand winters
Swiftly pass, I pray
I love you; I miss you
All these miles away

May all our dreams be sweet tonight
Safe upon my bed of moonlight
I know not of sadness, pain, or care
And when you dream, I'll fly away and meet you there
Sleep... Sleep... Sleep...

All of the lyrics I didn't change belong to Ponyphonic! I take NO credit except for the words I put in!
