While her Game of Thrones co-stars were busy posting emotional thank yous as the series finale aired on Sunday (May 19), Maisie Williams opted to share the beginning of her new chapter with Instagram followers by posting a photo of her trading in her icon Arya Stark brunette hair for bright blonde locks. She captioned the photos with a simple black heart.

Now that the iconic series has come to an end, the actors — many of whom rose to celebrity as the show aired — are all moving on with new projects. For the 22-year-old, that means starring in Marvel's The New Mutants as Wolfsbane, a teenage mutant who can turn into a wolf (fitting for the girl who played a Stark for eight years). She'll also currently filming a movie called The Owners, which is about a "group of friends [who] plot a burglary that spirals out of control."

Aside from acting projects, Williams will also be the Maid of Honor in her on-screen sister and real-life BFF Sophie Turner's wedding over the summer. Though she and her beau Joe Jonas recently tied the knot during a surprise ceremony in Las Vegas, they're still planning a more formal celebration in Paris.
