Only people who have seen death can see a Thestral. In the Harry Potter books, only Harry and Luna can see these creatures. While they look fearsome, they are actually quite gentle. Funny how looks can be deceiving sometimes. Ever had someone judge you because of the way you look? It happens all the time. We at Cardinal Tattoo believe the Thestral is just J.K. Rowling’s way of reminding us to be noble when faced with judgemental jerks.
