This story is a sequel to Entrenchment

An Age of Iron story.

At last, Ferrous Dominus is (mostly) secure.
Centaur III has been (largely) pacified.
The enemies of Chaos and Equestria have finally been crushed (probably).

But victory is merely a prelude to the next war. The Imperium of Man and the pitiful, far-flung holdings of the alien await the Iron Warriors and their new allies, ripe for conquest and plunder. With a new home world and a new ally under their thumb, the 38th Company at last turns its attention on a galaxy ablaze with constant war, seeking new victims to fill the bellies of their ships. The gentle but resourceful equines of Equestria travel with them, taking to the field not out of malice or avarice but gratitude in at last fulfilling their grave debt to the Legion.

But in the depths of the void, far beyond the fleet, beyond the veil of the Materium itself, Chaos is not idle. Plots advance, blood spills, and ancient evils seethe.

The light will be extinguished.

(for any G-fans, Xenilla is the kaiju you may know as Spacegodzilla. I changed the name because I got quirked about typing it repeatedly and am writing the story so it can at least be understood by just an MLP or just a G-fan; and thought it get very confusing that one character's name was just another character's name with an adjective. Also... don't pretend it's the most imaginative name Toho has every made)

Canterlot Castle's Royal Guards haven't had the best track record when it came to doing their jobs as Canterlot's defenders. This hasn't gone unnoticed by Princess Celestia and Princess Luna.

When the sisters pondered the reason for their guards' ineffectiveness, Luna concluded that Celestia's motherly nature toward her guards – as well as all her ponies – had prevented her from ensuring they received the proper training. Therefore Luna volunteered to personally turn the guards into buff, mean, fighting machines.

That is, if the guards could survive what the Princess of the Night had in store for them.

A well-led life runs into an end. If that was it, it would have been fine, but the forces of the universe were not content, finding another purpose, or perhaps reward, for this being in another world entirely. May she shine gently.

Key words: Human in Equestria, Human to Pony(but it's basically the start point), Transgender

Sweetie Belle just wanted to ask Twilight to help her get better in magic. Too bad she didn't choose a good time... One magical accident later, and she is now in a throne room in an unknown castle. Hopefully, the fat penguin on the throne will help her return to her home. Seeing his expression, it's not looking good...

Ooh boy...
