Solus Prime:
Fate has been cruel and death unkind
How can they do this to you?
The blame was our own, the death, yours
The Cybertron's silent today

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

Once did a prime whose shone like the sun
Look out on his race and sigh
He smiled and said, "Surely, there is no bot
So lovely and so well beloved as I"

So great was his reign and so brilliant his glory
That long was the shadow he cast
Which fell dark upon the brother he loved
And grew only darker as days and nights passed

Lullay prime, goodnight friend mine
Rest now in allspark's embrace
Bear up my lullaby, winds of the cybertron
Through cloud, and through sky, and through space

Carry the peace and the coolness of night
And carry my sorrow in kind
Garmadon, you're praised so much more than you know
Forgive me for not being there for you

Soon did that prime take notice that others
Did not give his friend his due
And neither had he cared him as he deserved
He watched as his friend's unhappiness grew

But such is the way of the limelight, it sweetly
Takes hold of the mind of its host
And that foolish prime did nothing to stop
The destruction of one who had needed him most

Lullay prime, goodnight friend mine
And rest now in allspark's embrace
Bear up my lullaby, winds of the cybertron
Through cloud, and through sky, and through space
Carry the peace and coolness of night
And carry my sorrow in kind
Garmadon, you're praised so much more than you know
May troubles be far from your mind
And forgive me for not being there for you

(Instrumental)

The years now before us
Fearful and unknown
I never imagined
We'd face them on our own
May these thousand winters
Swiftly pass, I pray
We prayed to you; We miss you
All these miles away

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

Sleep... sleep... sleep...

492 words A/N: the lullaby song gives me an idea to make the lyrics since the 13 primes mourns his loss when Lloyd arrives on cybertron he is Garmadon Prime's  successor not wanting to lose him just like Garmadon Prime died to protect Alpha Trion, Let me know if you think about the lyrics.
