I love this so much! The characterization of Arthur is perfect and you show Albus's strengths and flaws well without drifting into character bashing. I also love the perfectly in-character idiocy and brilliance of Merlin accidentally becoming part of the castle. Genius! And it sets up the ending very nicely as well. Good job!

An interesting story.

I have no words for how great this is.

Yes. That is something Merlin would do *facepalms*

My friends and I dug through the ungodly amount of HPMerlin crossover just so I can show this to them

Honestly this is still as good as I remember

Amazing, fantastic, awesome, brilliant, wonderful, perfect! You had no grammar mistakes, no punctuation mistakes no spelling mistakes and frankly your story was so great that I can forgive you for using 'mom'. Arthur was perfect and I can completely believe that Merlin would accidentally become a castle. I would love for you to write more but if you want to keep it as a one-shot that's fine too. Excellent work!

nice

This is amazing! And it almost made me cry when you finished with "Arthur had been his student for seven years, yet Albus had no idea who he was."

I love how Merlin accidently became Hogwarts and how he kept looking out for Arthur - it's such a Merlin thing to do really. :) Arthur's point about magic being limiting was very intriguing and I can see how that might be true, especially in this. One really great thing about this story is how Dumbledore, clever as he is, is shown to neglect the other students to focus on Harry (as he really does seem to do that) and it also shows that, as he said in the books, his mistakes are much bigger than a normal wizard's, as he definitely made mistakes with Arthur. This is clearly shown at the end where he still doesn't seem to understand what's going on because as Arthur's not very gifted with magic.

I loved this story. I have to say the part with Merlin in is my favourite because I love Merlin and he is just so typically...I don't know, Merlin (there's no other way to describe him). XD

This is simply wonderful. I found it amusing that Merlin accidentally became Hogwarts. I really like how Arthur isn't especially gifted with magic and that he is kept very much in character.

You wrote a good summary. I only actually fully realised what it meant at the start of the last section.

A very well written piece of fiction. It's great to not be picking up grammar, spelling and punctuation errors. It detracts from the pleasurable activity that is reading.

...He accidentally became the castle. Oops. How does that even-? Oh, MERlin...

Sorry. That was really amusing to me. Like "...well. Now what? Okay, no door for you... I can play with the-oops, didn't mean to drop them like-there, hover charm. Sorry about that."

...Sorry. Merlin AS Hogwarts. That's a... That's a new one. It makes me giggle.

Over all, though, fantastic story. I love it-Arthur's magic being a little odd, his frustrations. And the fact that Albus just... doesn't understand, even though he thinks he does. I think my favorite part (aside from Merlin accidentally becoming a castle) was when Arthur lost his temper enough to point out that the problem with all of these wizards is that, if anything, magic LIMITS their view... Interesting, and different take... I thought it quite creative.

Very smooth writing style, too. It's always nice to see proper grammar and properly spelled words on the internet... *sighs happily*

Okay, I've rambled enough now. Enjoyed the fic a great deal! Thank you so much for sharing.

Most assuredly worth the time to read and more.

This story was amazing! I loved how you didn't have Arthur be an awesome magician but instead be a borderline squib. I love that you kept the main traits of Arthur intact (just like Merlin said!) And I love that Arthur was reluctant to pull the sword out when it first appeared (though Harry honorably declined even though it was obvious he really really really wanted to).

Just a point of mythology - the sword in the stone was not Excalibur. I forget if the Merlin BBC series blends the two swords but in original mythology they were not the same.

Overall, a fantastic job on this story!

Oh my goodness, this is phenomenal! The way Arthur thinks and acts, he voices all the flaws in the magical world while also staying so in character. I really love how you've portrayed him. And then the whole thing about the castle helping him through the years and actually being Merlin. And how no one could pull Excalibur but he could. And Uther? And this story flows so well, it really has a sense of hidden magic. I love this! I know it's completed and you ended it in a really good spot, but maybe a few little clips of his years in Hogwarts etc?

Not what I was expecting but that was really good. You should do a sequel or something. This needs more. Really creative idea and good writing.
