I’m a PhD student, and university has been a major part of my life for 6 years now. I did my B.A. and M.A. at the same place where I am now, and I often felt that this is the place where I felt home the most, exactly the way Harry described Hogwarts, and probably Hermione - my favorite character in the books, felt so too.
The tattoo is dedicated to the books series. They have been a major part of my life for many years, and I specifically wanted something that has to do with them and not with the movies (although I like them as well). The Hogwarts crest appears at the beginning of every Harry Potter book, and it was an easy choice, relating to my university life.
The tattoo was done by the awesome Viktor Gor from Artist Tattoo (Israel).
