I appeared in Equestria one day, somehow transforming into my OC as well. Not wanting to risk the mane six discovering they're fictional characters in a fictional world, I've been avoiding Ponyville and spent my time trying to find a way home. Now that I accidentally ended up in Ponyville, I'll have to work harder than ever to keep my secret under wraps. But you can't keep secrets forever, and it's a lot harder to deal with when you're being plagued with nightmarish visions...

Self-insert, swearing, eventually crosses over with Doom 3, mild gore in later chapters.

Long ago, the Seraphim granted power to the Doom Slayer that he might conquer the forces of Hell. The Doom Slayer has won, Hell lies defeated, and now he returns to the Seraphim's holy realm. His mission is not over though, he has promises to fulfill, rewards to collect, and as always, evil to defeat. Let those who would harm this sacred land tremble, for the Guardian of Equestria, has returned!

(This story now has two sequels: Legion and the novella Doom Slayer.)
