There are actualy two good theme songs for this ship, Dynasty and Tears Ricochet. The one I want to focus on is Tears Ricochet.

That is the video, here is is my analysis of the lyrics:

*The first part is Darkstalker singing*

We gather here, we line up Weepin' in a sunlit room, and

When he tried to re-create Clearsight and kept failing
If I'm on fire, you'll be made of ashes too

How he wanted them to be immortals together
Even on my worst day, did I deserve, babe
All the hell you gave me?

Darkie keeps thinking he was not evil or mad with power, so why did she do this to him
'Cause I loved you, I swear I loved you
'Til my dying day                                                                                                                                                                   I didn't have it in myself to go with grace

Being put to sleep and seen as a villan is not a graceful way to dissapear
And you're the hero flying around, saving face

How Clearsight was seen as a hero, for 'defeating' him
And if I'm dead to you, why are you at the wake?

How she was still sad even though she was saving dragons
Cursing my name, wishing I stayed

the staying represents not going evil
Look at how my tears ricochet 

*Clearsight is singing now*

We gather stones, never knowing what they'll mean
Some to throw, some to make a diamond ring

How all their actions eventualy effected the future, the small moments that slowly pushed Darkstalker to villany
You know I didn't want to have to haunt you
But what a ghostly scene

That scene from book 9 with the marble
You wear the same jewels that I gave you
As you bury me

The jewels is the moonstone bracelet and burring her is him realizing that she is dead and has been for 2000 years

I didn't have it in myself to go with grace

Clearsight did not go with grace eather, betraying her true love, and then running away
'Cause when I'd fight, you used to tell me I was brave

How she used to try so hard to get a good, peaceful futre for them
And if I'm dead to you, why are you at the wake?
Cursing my name, wishing I stayed

How Darkstalker greved for her, and even tried to bring her back

Look at how my tears ricochet                                                                                                                                 And I can go anywhere I want
Anywhere I want, just not home

Clearsight never could go back to the Night kingdom or Pyhirra, because she would always feel a teptaion to free him
*Darkstalker*And you can aim for my heart, go for blood
But you would still miss me in your bones

How Clearsight regeted betraying him
And I still talk to you (when I'm screaming at the sky)

That same scene from book 9
And when you can't sleep at night (you hear my stolen lullabies)                                        *Clearsight*I didn't have it in myself to go with grace
And so the battleships will sink beneath the waves

How she, the NightWings, Fathom and Indigo all disapeared after he was put to sleep
*D*You had to kill me, but it killed you just the same
Cursing my name, wishing I stayed
*C*You turned into your worst fears                                                                                                                      

How he went evil, the worst futures happened

And you're tossing out blame, drunk on this pain
Crossing out the good years

How he blaimed Fathom for every
And you're cursing my name, wishing I stayed
Look at how my tears ricochet
