Kvothe's dad a pro musician = Harry's dad a pro quiditch player
yeah…dad was a master musician, so, what does he teach his son? Go figure? Harry finds out AFTER that his dad was a pretty shiny seeker, wow I'm just like my dad, he must have passed on the broom flying magi-gene to me!
From a literal tool POV, the quidditch was to give Harry a bond with his missing father, to give him the sense that he "knew" his father on a level.
For Kvothe, the music is a link that grounds him, giving him a continuation from his past life, to his new life. The one thing that was not stripped from his life when his LIFE was destroyed by the Chandria. Not just his parents, but his life. His parents, his friends, his travelling tribe.
It would be like if Harry had grown up with his parents, gone to Hogwarts, and then all his friends in Gryffindor, and all his family, and their friends were killed by Voldemort. His quidditch would then be Kvothe's music, but not until then.

- Both they're parents are dead

The key differences are that Kvothe knew his parents at a young age, and also never got a secondary father figure (at least not yet). At the same time, if you think orphan-heroes in fiction are all rips from Harry Potter, history would like to have a word with you. James Bond was a British orphan, that make Harry Potter a James Bond ripoff?

- they both want revenge on the killer(s)

Books. Do you read them? Orphaned kids wanting to take vengeance for the death of their parents isn't some great literary masterstroke that Rowling came up with. She did it well, and so did Rothfuss.

- Abenthy = Sirius Black
I'm not even sure how you got this one. Supplementary father figure? There are vague similarities between the two at best.

- University = Hogwarts
Fair enough, it's pretty safe to say that Hogwarts did popularize the notion of a magical school.

- Ambrose = Malfoy
We call those antagonists.

- Kvothe's talent with the lute = Harry's talent with a broom
Seriously? So is my friend who's really good at hockey a Harry Potter ripoff?

Kvothe's dad a pro musician = Harry's dad a pro quiditch player
See above.

More to the point, those are all superficial similarities. The characters of Kvothe and Harry are vastly different: Kvothe, for example, is much more of an asshole, and much less annoying (I love the Harry Potter series, but Harry got to be a bit weighed down by admittedly unavoidable angst after a while).

1. Kvothe actually knew his parents properly

2.If someone killed your family or destroyed something you loved then you would probably want revenge. (I would)

3.Abenthy is acctually nice, cool and a traveller(arcanist)person, also kvothe idolised him and Abenthy left at a very early stage in his life.

4.Kvothe's goal was to read at the archives from the moment he heard about it also he studied not just magic, he studied medical, mathimatical and other subjects too. He also had a deal with the university were they pid him for a little while, kinda like a schoolarship!!!

5.Are you stupid there's always some jerk snob at scool or some enemey you compete against.

6.Kvothe was good at everything and both his parents were very talented with music, he also learned to play until he was a total master at it at a super young age stranded in a forrest with the shock of the sudden death of his parents.

7. Both his parents were pro's not just one and also they both grew up with music with their lives as well as Kvothe so duh they were good.

And Anonymous if you do read this I'd like to see you write a book or serise that thousands or maybe millions love and know of so shut up and stuff it there are so many authors now days that you can do a lot of opitions but pat made work invinity times better then you could even do.

It's a lot harder than you think, you don't know everything just like me and everybody else.

Both they’re parents are dead
they both want revenge on the killer(s)
Abenthy = Sirius Black
University = Hogwarts
Ambrose = Malfoy
Kvothe’s talent with the lute = Harry’s talent with a broom
Kvothe’s dad a pro musician = Harry’s dad a pro quiditch player

Look for yourself, they’re are many more.

When you mentioned the worlds colliding, I definitely thought of fanfiction. Then I thought of cross-over fanfiction (a bane to the fanfic world that is very close to a Mary-Sue). And then, being a writer who used to breed fanfic plot bunnies, I began to wonder…

What ages are we talking about here? Shall we insert Kvothe into one of the school years or make some sort of interdimensional time-space continuum rift that causes him to be dropped into the current-day wizarding world with Harry being 29 years old. And is it the Kvothe who is a tavern keeper and probably in his late 20s or early 30s (because you kept mentioning he was younger than he looked), or the teenager who has yet to be thrown out of the university? Is it the Kvothe who may (possibly? maybe?) know the skill of naming with a strong profiency in sympathy magic, or the one who lost that ability?

So we either have two children, one who relies on a wand and one who doesn’t; two adults, one who is a strong wizard and one who used to be; or one child and one adult of varying degrees of magic.

And now I’ve gone off on a geeky tangent and possibly birthed a very complicated breed of plot bunny… hmm…

Most of the people on here were comparing the writing styles and plot, a few compared characterization and some compared the magic systems. Honestly, a collision of this magnitude would involve everything to be a decent story. Both characters have specialties, neither wish for much fame, and both are (in one way or another) pitted against a strong foe that killed their parents. But their personalities are vastly different (see Book 5 and on).

And I do have a question for you, but I figured it would be best to do my homework to see if you’ve already answered it. So fair warning, you might see more comments from me. ;) And because this turned out to be far lengthier than intended, I hope I haven’t annoyed/offended/evoked some sort of negative response from you…
