nice story

Stupid necromancers...

This story is decent enough so far, but I think that both you and Harry have no idea what the plot is supposed to be.
One of Harry's only goals in traveling back in time was to stop the Slytherins from making horcruxes and set them on the right path, but he did absolutely nothing about it until it was too late. And you kept going back and forth on whether Harry set out to seduce Rowena or if he just happened to fall for her.

There are also a ton of inconsistencies in the story. Off the top of my head, Godric and Salazar were fighting because Salazar told his students to fight the Gryffindors, and there were concerns about leaving Godric and Helga alone to run the castle, but then you said that it was summer and the students were gone. And you said that Marcello came to Hogwarts the second year it was open, so he couldn't have been there for more than a year before leaving, and yet he was able to teach the necromancers how to fight? That only makes sense if he was older than 11 when he came to Hogwarts, but then why wasn't he there the first year? But no matter what his age, he should not have been able to get away from Harry and Rowena. Harry's fight with Salazar lasted seconds. Even if we assume that you just did a really bad job of describing it and the actually took a while, he would not have been able to get all that far away. But then Harry is an idiot and waited until the morning to chase him, so he had plenty of time to get away. But even then, he should not have been able to get ahead of them by a week, plus however long he spent teaching the necromancers. Especially since Harry knew where he was headed. And Harry has absorbed the magic of dozens of Death Eaters and tons of magical knowledge. So why is he not obliterating everyone he fights? Those necromancers should have been a walk in the park for him. Sure, it makes the story less interesting if nothing challenges the characters, but that's the corner you've written yourself into by overpowering him.
Basically, your Harry comes across as kind of incompetent.

Still, I am interested enough to keep reading.

Unfortunately for you Salazar... Godric can fight Left handed...

This story reads about 30% flashback and 30% summary. It's an odd arrangement that feels lacking but did not get in the way of the narrative, much.

Then Harry's pursuit of Ravenclaw occured. It was hammy and mind boggling fast paced. They bared themselves during a first meeting and then met up a week later to begin a relationship?

Good story so far, though I think you’ve forgotten that Hogsmeade and Diagon Alley are not in the same place.

I’ve also noticed historical anachronisms, though they are minor and silly and if I wasn’t such a nerd I would never notice so don’t worry.

Great story! I really hope you don't stop, because I don't know if I have come across a finished story from this era. Keep going.

I read a very very very similar story to this one way before it was published on another site...

I am not sure why Harry would state his main reason for coming back is to stop Salazar from making the mistakes he made the first time...and then he pretty much does nothing until he has to kill him. I guess he forgot?

please update

This is great can’t wait for more

Wish he made a hidden House, Purple and White colours. Traits could be a blend of the four but a focus on (Good) Leadership.

Cool chapter!

I really liked this keep up the good work!

Fun class and lesson. I'm a bit confused with the story so far as I thought one of his main purposes was to help Salazar and his son no create a Horcrux and yet Harry has spent very little time even speaking with him. Good chapter and thanks for sharing!
