I’m doing this non-canon thing where I meld the Warhammer: Fantasy universe and the MLP universe together. And since the 40k and Fantasy universes are parallel you know there are gonna be “accidental” crossovers. Oh heck yeah. 

Anyway, in my own little melting pot of a universe, Celestia and Luna are the daughters of Sigmar and this unknown mare(let’s call her KitKat). The two sisters have KitKat’s coloration, but they get their powerful elemental magic from Sigmar, which is why both are able to raise their respective celestial bodies. However in order to leave behind a legacy and a guard against the growing darkness Sigmar freezes them in a sort of time slowing crystal(it could be Warpstone idk) to keep the sisters preserved till a powerful enough unicorn should come along and be able to free the two. This powerful unicorn turns out to be Starswirl the Bearded who finds Celestia and Luna in their old playroom, frozen in crystal. He manages to unfreeze them but since time had stopped within the crystal the poor fillies thought they were still in the Empire, even though it had fallen many years ago to Discord(a son of Tzeentch in my universe). Starswirl has to teach them about the more modern times and what is going on in what used to be the Empire. When Celestia and Luna grow up they gather pony forces together in a huge revolt against Discord and defeat him for good(almost). Celestia and Luna remain good friends with Starswirl and look to him as a sort of father/teacher. Both are angry at their father even though Sigmar was doing it for the best. Celestia is especially bitter because she feels responsible for Luna and can’t believe she let her dad trap her in the crystal. Celestia has not yet forgiven Sigmar, but Luna, the more quiet and contemplative one, is beginning to let it go. 

So that’s it, let me know what you think.
