Harry Potter: The Slytherin Magician

[Fate crossover, Harry Potter universe]

[The author is studying for graduate school entrance exams. The only thing I can't promise is that this will be completed.]

The original title of this story was What Does It Mean to Be a True-Blood Slytherin?

Ophelia Barthemelo Sainster is determined to apply to the Clock Tower when she turns eighteen, becoming an accomplished magus who will uphold her family's reputation.

But she never imagined that at the age of eleven, an owl would deliver a letter that got her sent off to a wizarding school called Hogwarts.

Does the Clock Tower accept students who graduated from Hogwarts but don't have a high school diploma?

Oh, well. Hogwarts is pretty great, actually.

The students are interesting, the spells are interesting, and the professors teach everything. They're not stingy like certain magus families. I absolutely love it here.

Oh! Spells are great! Knowledge is great!

Wizards even have spells that ignore defenses. Quick, I want to learn that one!

Huh? What? You're saying it's an Unforgivable Curse?

Oh, please. To a magus, there's no such thing as a spell you can't learn, my dear.

Magus are people who'll stop at nothing for knowledge.

Possible romance:

To a Barthemelo, no bloodline in the world is more noble than their own. True Barthemelos are extreme aristocrats. In their eyes, everyone else is truly equal.

So, pure-blood pride? Doesn't exist.

You think nobility is something written into your DNA? Don't make me laugh. True nobility is the knowledge passed down through a family's long history.

Only knowledge is supreme, my friend.

Reader's guide:

1. The author is a huge fan of Fate. This story grew out of a brainstorming session with a Harry Potter fan friend. The inspiration came from the Zhihu question, “What should you do if you receive acceptance letters from both Hogwarts and the Clock Tower?”

2. Barthemelo is just a background element and probably won't appear in the plot. The foremost of the Clock Tower's three great noble families, it holds true power in the Department of Politics and Law and is extremely aristocratic.

All you need to know is that this family is even more Slytherin than Slytherin.

3. If there's a pairing, the other character will be a Slytherin.

4. Inspired by getting hooked on a mobile game. Updates are irregular.

5. The heroine is genuinely powerful, and the story doesn't follow the original plot.
