The last installment of the Harry Potter series comes to theaters July 15, bringing an end to one of the most popular sagas of our time. It's been more than 14 years since the first Potter book hit shelves, and for many people, the books and films were formative experiences.
In fact, many people love Harry, Hermione, Voldemort, and Snape (yes, even Snape) so much that they've decided to commemorate them with tattoos. In honor of the entire Hogwarts crew, we asked 16 tatted-up Potter fans to tell us about how and why they got their pieces. From dark marks to Protego charms, read on to see some truly magic ink.
