Universal Orlando revealed its final guest for the 2018 Celebration of Harry Potter Thursday.

Natalie Tena, who played Order of the Phoenix member Nymphadora Tonks (but don't call her Nymphadora), will join fellow castmates Stanislav Yanevski (Viktor Krum), Bonnie Wright (Ginny Weasley) and James and Oliver Phelps (Fred and George Weasley) at the three-day Harry Potter event, Jan. 26-28.

Celebration of Harry Potter features a huge expo, Q&As with guests, wand combat demonstrations, film screenings and more, and takes place across both Universal Orlando and Islands of Adventure.

If Tena looks familiar outside of Harry Potter, she also played the Wildling Osha in the HBO fantasy series "Game of Thrones."
