This story is a sequel to The Conversion Bureau: Worlds Where It Wouldn’t Work

The Multiverse is a large place, and there are infinitely many versions of Celestia who, for one reason or another, thought it would be a good idea to turn humanity into ponies.

But as the old saying goes, "Anything that can go wrong, will go wrong."

The quasi-official sequel to the comedy fanfic by Sora2455 is here!

This story is a sequel to Split Second

Twelve years ago, she broke time. Two alternate timelines exist, each with a different version of Twilight Sparkle. Both versions of her are able to see the other. In this timeline, Sparkle is a Necromancer.

Or rather, she was. Sparkle is dead now, not that she cares. She's got a new body. With Thorn (her undead dragon son) and Cobalt (her apprentice and an assassin for hire) at her side, she's ready to take on the world. Again.

(Spoilers in the comments. Read at your own risk.)

This story is a sequel to Split Second and won't make sense without it.
This story also loosely shares continuity with Lupine Tree. Reading that is not required.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

After being tricked into using a forbidden spell to enter the void, Damon Lipton is turned into a Lich and thrown into Equestria by the God of Mischief. Dorian the Deranged. The God mistaking Damon for a follower of his.

Now stuck in Equestria, Damon finds himself thrown into a series of bizarre and epic adventures that will change his life, and those around him, for the better. And quite possibly for the worse.

Cover art is done by me.
