@DavidW There are several significantly different futhark/futhorc alphabets (I can think of three off the top of my head), so the question is not trivial.

@Randal'Thor - The question is also based on the premise that this image has anything to do with Harry Potter, which it does not.

@Silvermidnight "viking runes" is not a very precise term. But the "vikings" used Elder Futhark (and derivations), and yes, it does look exactly like this. --> en.wikipedia.org/wiki/Elder_futhark I don't know what other "viking runes" you might have found that are different...

@ibid As the answers below indicate, yes it does.

@Randal'Thor - The answer below do not indicate that OPs image has ever appeared in any HP related property.

@ibid The answer from SpaceWolf1701 gives textual proof that Ehwaz and Eihwaz were part of the fictional Ancient Runes course, so real historical runic letters were involved, therefore it makes sense that the alphabet they used in Ancient Runes was the Elder Futhark, of which the OP has included a picture. In the context of HP, the language used could be either Old Norse or a fictional one, but certainly the script used appears to be the one that the OP guessed at.

@Randal'Thor - That answer takes the image from the OP assuming it is genuine (which it is not), points out that two different real world alphabets have matching letters, and then uses the fact that the Ehwaz and Eihwaz are mentioned in the books to pick between the two. Ehwaz and Eihwaz are only being used to distinguish between the two alphabets, not to make the initial connection. The initial connection was based on the faulty information given in the question.

OP has labelled his image as coming from Pottermore, but I can't see any evidence that it's from that source. An identical image is posted onto the (fan-written) HP Wiki, which I suspect is what they mean

Amusingly, the first several runes in the image are F, U, TH, A, R, and K. (Admittedly, not something a person would recognize if they'd never heard the term.)

@Tom Why "amusingly"? That's literally the alphabetic order and the reason why we call it futhark (much like the word "alphabet" comes from the first two letters of the Greek script in order).

@Randal'Thor I find it amusing because it means the answer was right in front of OP the whole time. I'm familiar with futhark from video games, but never knew that was also the letter order. #TIL

@Randal'Thor Abjads too!

@Tom Thank you for pointing that out again, I have edited the question to fix my mistake. Is this better?

@Silvermidnight - Your new image is also not found in any Harry Potter property. Where are you finding these pictures?

@Silvermidnight - The video in my answer is not the movie. My answer was focused on the books are on other materials that JK Rowling would have been directly involved with. The Harry Potter movies are generally completely separate from the books and do their own thing. While their may be some examples of Runes in the movie, I can assure you that that specific image isn't in the movies either though.

@ibid I apologize for my stupidity. I will edit both images out of my question . . .

I am pretty sure I came across this language in Assasins Creed: Valhalla!
