Warning: Minor Spoilers ahead for "Game of Thrones" season seven.
"Harry Potter" alumni Jim Broadbent is the newest castmember to join "Game of Thrones." When Entertainment Weekly announced his casting last year, all we knew was that the role would be "significant."
Though we wrote about our best guesses for the character back in August 2016, we know have confirmation of Broadbent's role in the upcoming season. During an interview with ScreenCrush's Erin Whitney, Broadbent said: "I'm a maester, an archmaester. I'm an old professor character."

Broadbent also told ScreenCrush that he filmed scenes for five episodes. Since season seven will be shorter than previous installments, this means that Broadbent is set to appear in well over half of the season.
This new information, about Broadbent playing an "archmaester" for most of the season (along with EW's reporting of his role being "significant") makes us more certain than ever: Broadbent is almost certainly playing Marwyn the Mage.
Marwyn is a book character Sam Tarly meets when he arrives in the Citadel. Since Sam conveniently arrived in the Citadel at the end of season six, we had a feeling Marwyn would be showing up soon.

Marwyn, like Qyburn, is a maester known for exploring magic and rituals beyond the standard scope of healing. Upon meeting Sam in the books, he tells him that he knows about Daenerys and her dragons. Marwyn sets sail for Meereen not too long after, planning on meeting the Mother of Dragons himself.
Marwyn is also referred to throughout the books before we meet him. The witch Mirri Maz Duur — the woman responsible for Khal Drogo's death back in season one/book one— actually met him and said he taught her the Common Tongue.
Marywn also possesses a Glass Candle made entirely of obsidian — an object clearly tied to magic and possibly both dragons and the White Walkers and the Lord of Light Melisandre so fervently believes in.
We hope Marwyn's character will blow the lid on some seriously magical stuff in the coming season, and we can't wait to see Broadbent step into the role.
