Violet Harmony was born a few years later after the events of The Return of Tambelon. Twilight Sparkle and her husband, Courageous Heart, were happy with their firstborn child until they received an urgent message from Canterlot that Dismay and her army of Taraxippus who happen to be responsible for the death of Queen Cadence's father, King Raymond, before taking over The Praiziburg Kingdom and the fact that Queen Ligera risked her life to save Cadence while she was still an infant. Twilight Sparkle was determined to protect her country, but Courageous Heart knew that fighting the Taraxippus Army would mean facing death in battle, so he encouraged his wife to stay and take care of Violet Harmony before he joined the Equestrian Army to fight against Dismay and her army. When Courageous Heart fought against Dismay, he disappeared before the Equestrian Army presumed Courageous Heart the Champion of Light to be deceased. Twilight Sparkle was heartbroken before she had to raise her daughter until Flash Sentry became her new husband and Twilight gave birth to Evening Twinkle and Shooting Star when Violet Harmony was 5 years old. Violet Harmony knew what her biological father looked like before he disappeared in the battlefield against the Taraxippus Army and she didn't like the fact that her mom remarried and reproduced her half-siblings before Violet was determined to one day become the new Champion of Light like her father before her. That's when she sings this song from Quest for Camelot since Courageous-0f-Light made a scene in his MLP Fanfic where Courageous Heart and Twilight Sparkle sing their love song from Quest for Camelot.

Spoiler alert! Courageous Heart is still alive, he survived the battle with Dismay and her army, but he did suffered a near-death experience before he disappeared and woke up in a barren wasteland far away from Equestria because King Cosmos and Queen Galaxia failed to transport him back to his wife and daughter due to magic teleportation errors. Plus, Courageous Heart's "death" and disappearance was inspired by Superman's supposed death from Justice League Hereafter.

On My Father's Wings by The Corrs / Quest for Camelot

Violet Harmony (singing):
If you were with me now
I'd find myself in you
If you were with me now
Your the only one who knew
All the things we planned to do

I want to live my life
The way you said I would
With courage as my light
Fighting for what's right
Like you made me believe I could

And I will fly on my father's wings
To places I have never been
There is so much I've never seen
And I can feel his heartbeat still
And I will do great things
On my father's wings

This world I'll never see
My dreams that just won't be
This horse's stride
With one days ride
Will have covered more
Distance than me

But I will fly on my father's wings
To places I have never been
There is so much I've never seen
And I can feel his heartbeat still
And I will do great things
On my father's wings

Someday with his spirit to guide me
And his memory beside me
I will be free to

Fly on my father's wings
To places I have never been
There is so much I've never seen
And I can feel his heartbeat still
And I will do great things
On my father's wings
On my father's wings
