For hundreds of years, a cathedral has stood in the White Tail Woods undisturbed. That changed after a gemstone was stolen from the royal treasury and a group of guards go missing. Now, with magic anomalies spiking across the land and strange portals and creatures appearing out of nowhere, Twilight and friends are thrown into a conflict that will not only pit an ancient order against the Mane Six, but will also turn their home into a battleground as daedra, dragon, and pony clash against one another, and against each other, for the very soul of Equestria.

(A crossover between MLP:FIM and The Elder Scrolls V: Skyrim.)
