>>648902 Whaddya know, it kinda fits with these comments.

While I do have the headcanon that Sombra was Cadance’s father, I have some other things to it.
 
Like Sombra is actually Starswirl the Bearded after getting hopelessly corrupted by digging too deep into his studies on more and greater forms of magic. And Cadance is his (illegitimate) daughter.
 
Word got out, and ponies were still racist as all hell, so they’d kick Starswirl out of the newly-formed Equestria for having a pegasus daughter, after which they’d probably destroy his work.
 
So Starswirl did what he had to do: he encased his library in crystal and buried it deep underground. With the last and greatest burst of magic before becoming hopelessly corrupted, he put Cadance into a magical sleep, a suspended animation, encased her in crystal, and shot her far, far away.
 
Some 900 or so years later, (Cadance is somewhere between 25 and 30 years old, right?), the crystal pod containing Cadance fell out of the planet’s orbit. The force of descent and crash broke off all but the innermost layer of crystal. Said pod was found by earth ponies, who broke it open, reviving her, and so forth.
 
The Crystallized Library is still out there somewhere.

the fuk

Her mother? Celestia. (comic tie-in) Can’t admit it to the world that she fooled around with a tyrant, hence the “adopted niece”.
 
IT MAKES SOOO MUCH SENSE

I’ve always seen Sombra as a usurper. It fits with the whole “enslaving tyrant” thing.

Plot twist

Cadance got into an argument and ran from home when she was 6 - “mysterious orphan raised by pegasi” yeah right.

Wut
