(Prequel to Tears of a Fallen Star)
More than one thousand years ago, the world was a continuous string of wars. With nations at each other’s throats, leaders would place their trust in the assistance of mercenaries. But of all the mercenaries in the world, none were more feared than a special group known only as “The Cutters”. This group of three ponies, an earth pony and two pegasi were so feared that most nations would hesitate before hiring them. Mainly because their number one rule was to work for the highest bidder. Even if it meant killing their current contractor. With a past shrouded in mystery and a skill unmatched by any nation. these three mercenaries would kill without hesitation, without fear, and without mercy, a jewel for any nation’s military force. Yet there is more to them than what meets the eye.

Everyone knows that Sombra, the Tyrant of the Crystal Empire, got blown apart by the power of the Crystal Heart, but has yet to resurface. What everyone doesn't know is that he got blown across the sea of worlds, leaving fair Equestria behind. The problem is that when he awakens he has no idea who he is or where he ended up.

Will Sombra be able to let go of the past, and his hatred, in order to save a world he's never seen before? Or will the citizens of Tamriel have another villain to worry about?

After being pulled from his nearly nine-hundred year stretch of hell in the dark abyss that is the Twisting Nether to serve the new Lich King, the Archlich Kel'Thuzad was faced with the dilemma of freedom from his bindings to the Scourge. He had been an advisor and (somewhat twisted) friend to the most evil being in Azeroth's history for nearly 15 years. He had butchered and enslaved thousands, spit in and stepped on nature's face with the necromantic horrors that were created aboard Naxxramas, and was a generally annoying raid boss, all while under the cruel tyranny of Azeroth's previous Lich King, Arthas Menethil...
But, when an Equestrian Lich King is appointed by Death himself in exchange for immortality, Kel'Thuzad is in for the surprise of his unlife when he is thrown into a large room, with two comparatively small, sentient equines, who claim to be the reigning Prince and Princess of a kingdom.

The Imperium's Western Fringe Crusade discovers a remote planet and attempts to claim it for the Emperor. However, they encounter unusual local inhabitants, and they soon find that they are not the only ones who lay claim to this remote and strange domain....
MLP x Warhammer 40k Crossover

Sunset Shimmer fled from Equestria in search of the destiny that Celestia sought to deny to her. She dreamed of finding great glory and power in a strange new world. But she emerged on the other side of the mirror in a harsh cruel world beset by demons and troubled by division, conflict and racial animus: the world of Remnant.

Now, years later, Sunset has completed her studies at Canterlot Combat School and is ready to attend Beacon Academy. She hopes that in the more progressive Kingdom of Vale her appearance as a pony faunus will not be held against her the way it was in Atlas, and she can rise as high as her talents permit and seize with both hands the destiny she still yearns for.

Sunset finds herself assigned to lead three fellow freshman at the Huntsman Academy: Jaune Arc, who dreams of becoming a hero elevated above all others; Pyrrha Nikos, a peerless warrior who has everything that Sunset wants and hates everything about it; and Ruby Rose, a simpler and more honest soul who simply wants to save as many people as she can, and who might just light the way to their salvation.

Together they are Team SAPR, and together they are plunged into a world of mysteries, magic, allies and enemies, robot girls and Atlasian black ops experiments. It won't be easy, but if they can work together, teach Jaune how to fight and maybe learn to get along as friends along the way, then they might just save the world.
