Meh, I’m going with my head canon that the crystal royalty royalty escaped the curse and Cadance was just born around the same time as Shining, and maybe Sombra is part of her family.

Then why was she obviously a teen in Twilight’s flashback?

Alternatively, she’s a clone of a previous Crystal queen created by Celestia for the purpose of installing a puppet ruler in the Crystal Empire.

BP, or she escaped before the empire was sealed and has been waiting for a thousand years to return…

She is the “Crystal Princess” Her cutie mark is the Crystal Heart… The crystal ponies disappeared 1000 years ago.. I think it is obvious.. Her parents used a time travel spell 1000 years ago. She was the only survivor to make it out of the Crystal Empire safely by escaping into the future when she was just a filly.

Such is the life of an Immortal.

We wish she was

thats…sad :/

We don’t even know how old she is, she may be just as old as Shining…

In a way, I think you were.

:(
