This story is a sequel to Dresden Gets Schooled

Harry Blackstone Copperfield Dresden's life has been even stranger than usual ever since he first got involved with Equestria. However, after his last adventure sent him to some strange high school dimension, things have finally settled down into something approaching normalcy. Or at least as normal as Harry's life ever gets. His new apprentice Sunset Shimmer is proving to be quite a handful, but Harry has experience with handling headstrong young women.

However, things take a turn for the worse when he learns that a new threat from Equestria has made its way to Earth. And naturally it's up to him to stop the Sirens before they rock the world's foundations.

MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

The first time it happened, Sunset didn’t pay it any mind due to the circumstances. The second time it happened, she noticed it and brushed it off as the action of a concerned friend. The third time it happened, she finally figured out that Rarity was flirting with her.

Jak never found it unusual that he had a unicorn brother. Shining Armor had been there his entire life, as far as he could remember. Sure, Daxter often made a point of just how strange it was relative to everyone else in the village, but then again Jak himself was different from the rest of the villagers.

He never questioned that he looked somewhat different from everyone else. Never questioned that he was raised by Samos the Sage, alongside Samos' daughter Keira, whom he kinda-sorta liked and who kinda-sorta liked him, even if Samos himself didn't like that. Jak, by nature, wasn't the sort to question things.

Shining Armor, on the other hand - or hoof - had lots of questions, but no answers.

...yet.

A dark period in the world's history. With the rise of Reploids, society was thought to enter a new golden age...until the rise of the Mavericks.
